• PON mengijiinkan banyak pelanggan untuk berbagi koneksi yang sama dari STO atau headend tanpaadanya perangkat aktif • Kabel feeder dari OLTdi STO dihubungkan ke spliter optik pasiv, yang biasanya menghubungkan 32pelanggan pada fiber optic core yang sama pada kabel feeder • Masing2 pelanggan disediakan ONT yang terhubung ke masing2 cabang optical pasive splitter • Arisitektur point to multi point ini secara drastis mengurangi instalasi jaringan, management, dan biaya

Penempatan Optical Split ter

• Kabel FO Feeder membawa sinyal optik antara STO/headend dan splitter yang mengijinkan beberapa ONT untuk terhubung ke 1 fiber yang sama• ONT dibutuhkan di masing2 pelanggan dan memberikan berbagai servis seperti video, telepon dan internet data)• Ada beberapa pendekatan arsitektur jaringan untu menghubungkan pelanggan ke PON . Yang paling sederhana adalah menggunakan single splitter

seperti pada gambar (a), tetapi beberapa tingkat splitter dapat digunakan juga seperti pada gambar

Topologi PON yang lain

• Topologi tambahan juga dapat digunakan seperti Star, Bus dan Ring seperti gambar dibawah dimana juga diaplikasikan pd jaringan LAN• Pada beberapa instalasi, tidak diperlukan menarik fiber sampai ke semua pelanggan . Maka fiber akan berhenti di ONU, yang

secara fungsi sama dengan ONT. ONU diletakkan dekat dengan pelanggan (FTTC) dan sambungan terakhir akanmenggunakan copper twisted pairs. Jaringan ini biasanya mendukung VDSL, meyediakan bandwidth yang cukup untuk tripleplay pada jarak pendek

PON Deployment

Baru-baru ini diperkenalkan standard baru seperti yang telah di rekomendasikan oleh ITU-T (G 983) danI.E.E.E. Yang teleh meningkatkan kehandalan, kemanan, keseragaman desain, kapasitas, dan tingkatkeekonomisan yang lebih baik yang secara signifikan mengurangi biaya jaringan Fttx

FTTx mengkombinasikan PON dengan biaya yang lebih rendah pada yang mampu untuk memberikanservice sebagai berikut ::

• Jaringan telepon dari STO - ke pelanggan

• Headend-ke –pelanggan pada jaringan CATV

• Kantor pemerintahan pusat/daerah-ke-kantor2 pelayan publik atau untuk sentra monitoring untukdata/voice interchange/ dan security/traffic management control

• Perusahaan utilitas seperti Listrik, Air, Gas untuk remote meter-reading

• Jaringan untuk bisnis kecil dan menengah

• Pembelajaran jarak jauh; Telemedicine; On-line Gaming; Video Conferencing

Fig. 33 Splitter Insertion Loss

Passive Optical Splitters divide the input power (P i) between the outputsaccording to the split, see Fig.33.For the two-way split, the theoretical output power from each output willbe50% of the input power (P i / 2) and for the 4-way split each output will be25%of the input power (P i / 4 ), etc.Thus with an input power of 1 mW ( 0dBm), each output will be 0.5 mW(- 3dBm) for the 2-way split and 0.25 mW (-6dBm) for the 4-way splitThe theoretical insertion loss for different equal splits are given below:

Split Output Power at each output (% of P i) Insertion loss (dB)1 x 2 50% 3dB1 x 4 25% 6dB1 x 8 12.5 % 9dB1 x 16 6.25% 12dB1 x 32 3.125% 15dB

** It should be noted that, contrary to what might be expected, splitters add approximately the sameloss when used as combiners for light travelling in the ‘upstream’ direction


16/29


• In practice the insertion loss will be slightly higher and the table below gives example values for actual splitter devices.

• The ITU-T G693 recommendation calls for a maximum split up to 32, but 64 splits are also being considered as thissplit would

be more suitable in some applications, such as CATV

Split Split Ratio Device Insertion Loss( dB)

1 x 2 (50/50) ≤ 3.3 /3.6 dB1 x 2 (45/55) ≤ 4.1 / 3.1 dB1 x 2 (40/60) ≤ 4.7 /2.7 dB1 x 2 (35/65) ≤ 5.3 /2.3 dB

1 x 2 (30/70) ≤ 6.0 /1.9 dB1 x 2 (25/75) ≤ 6.8 /1.5 dB1 x 2 (20/ 80) ≤ 7.9 /1.2 dB1 x 2 (15/85) ≤ 9,3 /0.9 dB1 x 2 (10/90) ≤ 11.3 /0.6dB1 x 4 ≤ 7.0 dB1 x 8 ≤ 11.0 dB1 x 16 ≤ 14.3 dB1 x 32 ≤ 17.8 dB

• The split ratio (50/50 or 30/70 etc.) of a 2-way split may be chosen to adapt to various loss budgets for particular PONs

• One of the challenges the network designer faces is how to accommodate uneven counts that do not match standardsplit ratios

Neglecting fibre losses, the theoretical outputs from S1 will be -3dB down on P i, the outputs from S2 and S3 will be -12 db down(-3 + -9dB) on P i and the outputs from S4 will be -15 db down on P i (-12 + -3 dB)In practice, fibre and other losses are important considerations to be covered under ‘loss budget’, see later.

Question

If the input power to S1 is -10 dBm, what will be the theoretical outputpower in dBm at premises (a) C (b) H (c) O, neglecting fibre losses ?

Solution(a) -22 dBm (b) -25 dBm (c) -22 dBm

Note that the signal at premises H and I are 3dB down on the signal atall other premises


19/29


Connectors

Connectors are fitted at various points in a PON system (patch panels, attenuators,OLT, ONT).The important connector parameters specified by the ITU-T G671 recommendation are:

Insertion loss

This is the loss or attenuation introduced by the connector in the signal path and iskept as small as possible since connector attenuation contributes to the overallsystem signal loss.

Performance insertion loss is -0.5 dB per connection.

Back Reflections

Back reflections from a connector must be reduced to a minimum. This is particularlytrue for high power analogue video signals from narrow band lasers, because strongreflections will degrade the video transmission quality.Back reflections are measured in terms of the connector ‘Optical Return Loss’, where:

Optical return loss = Reflected signal power (expressed in dBs)Incident signal power

Performance Optical Return Loss is -35 dB (or better)

The types of connectors used in Passive Optical Networks is not specified by the PONStandard. However, manufacturers may specify particular connector types to tailor

specifications to provide optimum performance levels of their systems and products.

Fibre Optic Cable

Fig.36 Loose Tube Armoured Cable withfibre count 12-48 (Single mode)

-suitable for direct burial

The common fibre considered for PON systems is the recommendedITU-G652, standard single mode with zero chromatic dispersion at the

1310nm wavelength and higher dispersion (18 ps/nm/km) at 1550 nm, the wavelength

optimised for lowest attenuation. The graph of Fig.37 showsDispersion plotted against Wavelength

Attenuation should be less than 0.35 dB/km at 1310 nm, since the challengein PONs is to ensure that sufficient optical power arrives at the ONT tooperate its receiver correctly to provide the network services.

21/29


Attenuators

Attenuators may be used in PONs to reduce the optical power arriving at thereceiving end of a system to prevent the optical receiver from overloadingand creating system errors. Attenuators introduce loss into a system and the amount of loss may bevariable or it may be fixed. The diagrams of Fig. 39 show fixed attenuators which areavailable in a variety of loss values, e.g., 1 dB, 3dB, 5dB, 10dB, 15dB and 20 dB and aresupplied with or without connectors.

Attenuators may be wavelength specific (see Fig. 40) or non-specific. It is thus importantto ‘match’ attenuation and return loss of the attenuator with the operating wavelengthsused in PON-WDM systems.Manufacturer’s specifications should be considered when selecting an attenuator as itmay block other wavelengths used in the system
