1.25Gb/s 1310nm Single-mode SFP Transceiver

Kufotokozera Kwachidule:

Ma transceivers a Small Form Factor Pluggable (SFP) amagwirizana ndi Small Form Factor Pluggable Multi-Sourcing Agreement (MSA). Transceiver ili ndi magawo anayi: dalaivala wa LD, amplifier yolepheretsa, laser FP ndi PIN photo-detector. Deta ya module imalumikizana mpaka 20km mu 9/125um single mode fiber.

Kutulutsa kwamaso kumatha kuzimitsidwa ndi kuyika kwapamwamba kwa TTL kwa Tx Disable. Tx Fault imaperekedwa kuti iwonetse kuwonongeka kwa laser. Kutayika kwa siginecha (LOS) kumaperekedwa kuti ziwonetse kutayika kwa chizindikiro cha wolandila kapena ulalo ndi mnzake.

Ndemanga:
1.Circuit ground ndi yotalikirana ndi chassis ground.
2.Laser linanena bungwe woyimitsidwa pa TDIS>2.0V kapena lotseguka, wothandizidwa pa TDIS <0.8V.
3.Kuyenera kukoka ndi 4.7k - 10kohms pa bolodi khamu kuti voteji pakati 2.0V ndi 3.6V.MOD_DEF (0) chimakoka mzere otsika kusonyeza gawo ndi plugged.
4.Iyi ndi njira yosankha yomwe imagwiritsidwa ntchito poyang'anira bandwidth yolandila kuti igwirizane ndi ma data angapo (mwinamwake Fiber Channel 1x ndi 2x Rates) .Ngati ikugwiritsidwa ntchito, zolowetsazo zidzalowetsedwa mkati ndi> 30kΩ resistor. Mayiko olowera ndi:
- Pansi (0 – 0.8V): Bandwidth yachepetsedwa
- (> 0.8, <2.0V): Zosadziwika
- Pamwamba (2.0 - 3.465V): Bandwidth Yathunthu
- Tsegulani: Bandwidth yochepetsedwa
5.LOS ndi lotseguka wokhometsa linanena bungwe ayenera kukoka ndi 4.7k - 10kohms pa gulu khamu kuti voteji pakati 2.0V ndi 3.6V. Logic 0 imasonyeza ntchito yachibadwa; logic 1 ikuwonetsa kutayika kwa chizindikiro.
