Specification
1394 Trade Association Specifications are developed within Working Groups of the 1394
Trade Association, a non-profit industry association devoted to the promotion of and
growth of the market for IEEE 1394-compliant products. Participants in Working Groups
serve voluntarily and without compensation from the Trade Association. Most
participants represent member organizations of the 1394 Trade Association. The
specifications developed within the working groups represent a consensus of the
expertise represented by the participants.
Use of a 1394 Trade Association Specification is wholly voluntary. The existence of a
1394 Trade Association Specification is not meant to imply that there are not other ways
to produce, test, measure, purchase, market or provide other goods and services related to
the scope of the 1394 Trade Association Specification. Furthermore, the viewpoint
expressed at the time a specification is accepted and issued is subject to change brought
about through developments in the state of the art and comments received from users of
the specification. Users are cautioned to check to determine that they have the latest
revision of any 1394 Trade Association Specification.
Comments for revision of 1394 Trade Association Specifications are welcome from any
interested party, regardless of membership affiliation with the 1394 Trade Association.
Suggestions for changes in documents should be in the form of a proposed change of text,
together with appropriate supporting comments.
Interpretations: Occasionally, questions may arise about the meaning of specifications in
relationship to specific applications. When the need for interpretations is brought to the
attention of the 1394 Trade Association, the Association will initiate action to prepare
appropriate responses.
Comments on specifications and requests for interpretations should be addressed to:

4 HPCF Requirement
This clause defines a new media and connectors in order to support the automotive requirements. This new class of
unique HPCF automotive connectors and cable contained in this clause will be defined for implementation within
ground vehicles. The connector interface is useable from S200 to S800 dependent on the fiber and optical
transceiver capabilities.
The products defined in this clause shall meet Class 1 Eye Safety requirements without requiring ―Open Fiber
Control‖ monitoring circuits.
Eye safety requirements are specified in the IEC-60825-1.
Laser eye safety is a measure of how vulnerable the eye is to damage from a particular laser source. This
vulnerability is primarily affected by the output power and wavelength (color) of the laser light. Class 1 laser
devices are the safest and Class 3 laser devices are the least safe.
4.1 Performance Criteria
4.1.1 Embedded Network
The power budget has loss allocations for HPCF cable, coupling of interconnects, bends through a minimum
specified radius, temperature aging of the transceivers and the optical fiber along with system margin.
Number of Maximum Inline HPCF Connections
Maximum Node-to-Node
Total Distance
3
10 meters
Table 4-1: Number of Maximum Inline HPCF Connections
4.1.2 PMD block diagram
For system conformance, the PMD sublayer is standardized at the following points:
- The optical transmit signal is defined at the output end of a 1m patch cord (i.e., TP2) of a type
consistent with the connection type connected to the transmitter receptacle defined 4.2.
- The optical receive signal is defined at the output of the cable plant (i.e., TP3) connected to the
receiver receptacle also defined in 4.2.
TP1 and TP4 are standardized reference points for use by implementers component conformance. The electrical
specification of the PMD service interface (i.e., TP1 and TP4) are not system compliance points (as they may not be
ready testable in a system implementation).

The HPCF core shall be protected within a cylindrical cavity in both the HPCF inline cable plug and socket to
prevent damage to the end faces when contacted to a flat surface. The cylindrical cavity prevents optical surface
from getting damages. A dust cover or boot should be used to prevent damage during shipping and handling prior to
final assembly.
4.1.4 HPCF Cable
The HPCF cable must function within and in vehicle automotive environment with the following minimum to
maximum temperature ranges:
Temperature Ranges Class 105
Ambient Temperature -40ºC to +105ºC

The HPCF cable shall have a step index core of glass. The HPCF cable core diameter shall be 200 ± 5µm and the
clad diameter shall be 230 +0/-10µm with an Effective Numerical Aperture (NA) 0.37 ± 0.02. The HPCF cable
construction may be either single or dual jacketed and single or duplex core.
A minimum permanent bending radius of 15mm shall not affect cable performance. The attenuation change shall be
within ±0.5dB from initial attenuation after exposing to environmental tests which are performed based on
performance groups B, C and D.
Depending on the specific requests of the implementer, the HPCF cable supplier(s) may be required to provide the
additional performance data. This data may include spectral attenuation, test procedure IEC 60793-1-40, numerical
aperture, test procedure TIA/EIA-455-7, bandwidth, test procedure IEC 60793-1-41. These tests have not been
included in this specification.
4.1.5 Fiber Optic Transceiver
The FOT is incorporated into the HPCF header socket. A reference performance validation sequence is provided to
assist in the connector manufacturer‘s qualification of FOT devices to minimize risk in the integration with the
header.
The fiber optic transceiver shall be capable of working in both a 3.3 ± 0.3Vdc and/or 5.00 ± 0.25Vdc voltage
systems.
The fiber optic transceiver shall have a minimum extinction ratio of 5dB with a maximum overshoot of 25%.
The fiber optic transceiver shall be capable to couple or receive the required optical power in or out of a fiber, when
the center of the end face is located inside the green area which is described in Fig 4-2. The center wavelength @
25ºC shall be 850nm with a maximum spectral width (FWHM) of 10nm. The minimum launch power at TP2 shall
be -6.5 dBm OMA over the temperature range of the class of the HPCF header. The maximum launch power shall
be compliant with IEC-60825-1over the temperature range of the class of the HPCF header.
The fiber optic receiver shall have a minimum receiver input power of -15.4 dBm OMA at TP3 and shall receive the
maxim launch power of the fiber optic transmitter. Temperature range is based on the class of the HPCF header with
integrated FOT.
A reference of the power budget diagram is shown in Annex A.

4.3 Performance Validation
Table 1 in ANSI/EIA 364-D(01)shows operating class definitions for different end use applications. The test specifications follow the recommendations for environmental class G2.1 that defines ―Year round exposure to heat, cold, humidity, moisture, industrial pollutants and fluids‖. The Equipment Operating Environmental Conditions shown for class G2.1 are modified for: Temperature from -40ºC to +85ºC. Class 1.3 further describes as operating in maximum humidity of 95% a ―harsh environment‖. Marine atmosphere is not anticipated in this implementation.
Samples sizes have determined based on a standard known sampling procedure.
Unless otherwise specified, all measurements shall be made within the following ambient conditions:
a. Temperature: 18ºC to 28ºC
b. Atmospheric pressure: 86kPa to 106kPa
c. Relative humidity: 25% to 75%
Special tests may require tighter control of conditions and are specified in the test procedure.
This standard utilizes VCSEL FOT, for reference, and therefore does not require return loss or reflectance
measurement in the testing sequence. If an FOT, other than an VCSEL is chosen, the implementer may request the
supplier(s) to provide additional data. This data may include Return loss or reflectance performance data using either
IEC 61300- 3-6 or ANSI/TIA/EIA 455-107-A(99)test methods.
Depending on the specific location of the embedded network, the implementer may request the HPCF supplier(s) to
provide the additional environmental performance data. Salt Spray, test method ANSI ANSI/TIA/EIA 455-16-a(91),
and Corrosive Environment, test method ANSI/EIA 364-65-A(98). The environments may include.

5 AGF Requirement This clause defines a new media and connectors in order to support the automotive requirements. This new class of
unique AGF automotive connectors and cable contained in this clause will be defined for implementation within
ground vehicles. The connector interface is useable from S200 to S800 dependent on the fiber and optical
transceiver capabilities.
The products defined in this clause shall meet Class 1 Eye Safety requirements without requiring ―Open Fiber
Control‖ monitoring circuits.
Eye safety requirements are specified in the IEC-60825-1.
Laser eye safety is a measure of how vulnerable the eye is to damage from a particular laser source. This
vulnerability is primarily affected by the output power and wavelength (color) of the laser light. Class 1 laser
devices are the safest and Class 3 laser devices are the least safe.
5.1 Performance Criteria
5.1.1 Embedded Network
The power budget has loss allocations for AGF cable, coupling of interconnects, bends through a minimum
specified radius, temperature aging of the transceivers and the optical fiber along with system margin.
Number of Maximum Inline AGF Connections
Maximum Node-to-Node
Total Distance
3
10 meters
Table 5-1: Number of Maximum Inline AGF Connections
5.1.2 PMD block diagram
For system conformance, the PMD sublayer is standardized at the following points:
- The optical transmit signal is defined at the output end of a 1m patch cord (i.e., TP2) of a type
consistent with the connection type connected to the transmitter receptacle defined 5.2.
- The optical receive signal is defined at the output of the cable plant (i.e., TP3) connected to the
receiver receptacle also defined in 5.2.
TP1 and TP4 are standardized reference points for use by implementers component conformance. The electrical
specification of the PMD service interface (i.e., TP1 and TP4) are not system compliance points (as they may not be
ready testable in a system implementation).

Either an integrated or discrete ferrule design shall be the option of the manufacturers. Each mated connector pair
must withstand 20 mating and unmating cycles. A locking mechanism is employed to retain the plug and socket.
Safe disconnect shall occur without damage to either the latching mechanism or the AGF fiber. The maximum
insertion force of the mated connectors is 45N, and the locking mechanism shall have minimum pullout strength of
100N.
The AGF cable shall have minimum single core pullout strength from the AGF cable connectors of 60N, pulling
only one of the two AGF cores. This requirement applies to both the AGF inline cable plug and AGF inline cable
socket connectors.
Insertion loss of an inline connector shall be equal to or less than 2.5dB. See the TA document 2001018 for
connector requirements.
The AGF core shall be protected within a cylindrical cavity in both the AGF inline cable plug and socket to prevent
damage to the end faces when contacted to a flat surface. The cylindrical cavity prevents optical surface from getting

5.3 Performance Validation
Table 1 in ANSI/EIA 364-D(01)shows operating class definitions for different end use applications. The test specifications follow the recommendations for environmental class G2.1 that defines ―Year round exposure to heat, cold, humidity, moisture, industrial pollutants and fluids‖. The Equipment Operating Environmental Conditions shown for class G2.1 are modified for: Temperature from -40ºC to +85ºC. Class 1.3 further describes as operating in maximum humidity of 95% a ―harsh environment‖. Marine atmosphere is not anticipated in this implementation.
Samples sizes have determined based on a standard known sampling procedure.
Unless otherwise specified, all measurements shall be made within the following ambient conditions:
a. Temperature: 18ºC to 28ºC
b. Atmospheric pressure: 86kPa to 106kPa
c. Relative humidity: 25% to 75%
Special tests may require tighter control of conditions and are specified in the test procedure.
This standard utilizes VCSEL FOT, for reference, and therefore does not require return loss or reflectance
measurement in the testing sequence. If an FOT, other than an VCSEL is chosen, the implementer may request the
supplier(s) to provide additional data. This data may include Return loss or reflectance performance data using either
IEC 61300- 3-6 or ANSI/TIA/EIA 455-107-A(99)test methods.
Depending on the specific location of the embedded network, the implementer may request the AGF supplier(s) to
provide the additional environmental performance data. Salt Spray, test method ANSI ANSI/TIA/EIA 455-16-a(91),
and Corrosive Environment, test method ANSI/EIA 364-65-A(98). The environments may include.

Annex A (informative)
Example of system power budget for HPCF
The optical power budget requires a differential of 8.9dB between the optical transmitter and receiver port at a
reference distance of 10 meters. The optical power budgets are typically specified from/to the fiber optics
transceiver attachment points to the printed circuit board at both ends. This method is not utilized within the
specification since it does not guarantee power levels at the connector interface. For reference, 8.9dB transceiver-to-
transceiver power budget was used when determining the 8.9 dB power budget requirement specified below. This
guarantees operability between all optical devices of the IDB-1394 HPCF embedded network.
A.1 Theoretical Total Power Budget
S800 operation (Frequency of 1,000 M board)
Mean Launch Power (OMA): Pf = -6.5 dBm
Minimum FOT Input power(OMA): Pin = -15.4 dBm
Minimum Power Budget: Budget = |Pin-Pf| = 8.9 dB (1)
A.2 HPCF Cable
Maximum HPCF Cable Loss: 0.02 dB/m (2)
A.3 In-Line HPCF Connector
Maximum Loss in each Inline HPCF Connector Pair 2.5 dB (3)
A.4 Bending, etc.
Maximum Loss of HPCF Cable for Bending (R15mm, 4 turns) 1.2 dB (4)
A.5 System Margin (Two Inline HPCF Mated Connectors and 9 Meter Total Length of HPCF Cable)
System Margin = (1) –{[(2) x 9meters] + (3) + (4) }
= 8.9 – {0.02 x 9 + 2.5 x 2 +1.2}
= 2.52 dB
