Optical Fiber Specifications

Data Sheet

G.651Multi-mode Optical Fiber

Standard 50/125 µm fiber

1. General

This specification covers the design requirements and

performance standards for the optical fiber described

below. This fiber is used in the optical cables. The

features described in this document are intended to

provide information on the performance of the optical

fiber and aid in handling and use. Refer to the

appropriate cable specification for details regarding

the finished cable's performance.

1.1 Fiber Description

The Standard Multimode (MM) optical fiber used is

a graded index fiber with glass core, glass cladding

and dual acrylate protective coatings. This Type Ia

TIA specified fiber is optimized for operation at both

850 and 1300 nm transmission windows. It is fully

compatible with commercially available splicing and

connector products and can be spliced to other

commercially available 50 µm MM fibers. The 50

µm MM fiber is ideal for data and local area

networks.

1.2 Quality

4SProducts ensures a continuing level of quality in

our optical fiber products through multiple programs

including ISO 9000. Quality product is guaranteed

and is evident in the optical fiber cable products

supplied by 4SProducts.

1.3 Reliability

4SProducts ensures product reliability through

rigorous qualification testing of each product family

to meet or exceed industry standards. Both initial

and periodic qualification testing are performed to

assure the fiber's performance and durability in the

field environment.

2. Fiber Design

3. Testing & Inspection

The optical properties of all fibers are measured

prior to cable manufacturing with bi-directional

OTDR and remain traceable through-out the

manufacturing process and the lifetime of the

cable. After cabling, 100% of all fibers in each

length of cable are measured at all operating

wavelengths. The attenuation for each fiber is

recorded.

Only the highest quality Multi-Mode fibers in our cables

50 µm Multimode (MM) optical fiber manufactured by the

Modified Chemical Vapor Deposition (MCVD). This high

quality glass has excellent geometry, high strength

characteristics, high bandwidth, and low attenuation. The

MM fiber is fully compatible with other commercially

available MM fibers and is optimized for transmission at

850 and 1300 nm wavelengths.

The 50 µm MM fiber is a graded index design. Its

optical properties are achieved through a Germanium

doped silica based core with a pure silica cladding. A

dual acrylate protective coating is applied over the

glass cladding to provide the necessary bending and

tensile strength required for handling in the field and to

ensure maximum fiber lifetime through increased

reliability.
