I-1.25Gb/s 1310nm I-SFP Transceiver yemowudi enye

Umfanekiso oBonisiweyo we-1.25Gb/s 1310nm SFP Transceiver yemowudi enye

Inkcazo emfutshane:

Ii-transceivers zeSmall Form Factor Pluggable (SFP) ziyahambelana neSmall Form Factor Pluggable Multi-Sourcing Agreement (MSA). I-transceiver inamacandelo amane: umqhubi we-LD, i-amplifier enomda, i-FP laser kunye ne-PIN photo-detector. Idatha yemodyuli iqhagamshela ukuya kuthi ga kwi-20km kwi-9/125um single mode fiber.

Isiphumo sokubona singacinywa ngokufaka i-TTL logic ephezulu ye-Tx Disable. I-Tx Fault ibonelelwa ukubonisa ukonakala kwe-laser. Ukulahleka kwesiphumo sesiginali (LOS) kubonelelwa ukubonisa ukulahleka kwesignali yokubona yokufaka yomamkeli okanye imeko yekhonkco neqabane.

Amanqaku:
1. Umhlaba wesangqa uhlukaniswe ngaphakathi nomhlaba we-chassis.
2. Ukuphuma kwelaser kukhutshaziwe kwi-TDIS >2.0V okanye kuvuliwe, kuvuliwe kwi-TDIS <0.8V.
3. Kufuneka itsalwe phezulu nge-4.7k - 10kohms kwibhodi yomncedisi ukuya kwi-voltage ephakathi kwe-2.0V kunye ne-3.6V. MOD_DEF (0) itsala umgca osezantsi ukubonisa ukuba imodyuli ixhunyiwe.
4. Le yi-input yokuzikhethela esetyenziselwa ukulawula i-bandwidth ye-receiver ukuze ihambelane namazinga edatha amaninzi (mhlawumbi i-Fiber Channel 1x kunye ne-2x Rates). Ukuba iyasebenza, i-input iya kutsalwa ngaphakathi nge-> 30kΩ resistor. Iimeko ze-input zezi:
- Ephantsi (0 – 0.8V): I-Bandwidth Encitshisiweyo
- (>0.8, < 2.0V): Ayichazwanga
- Phezulu (2.0 – 3.465V): I-Bandwidth epheleleyo
- Ivuliwe: I-Bandwidth Encitshisiweyo
5. I-LOS ivuliwe, imveliso yomqokeleli kufuneka itsalwe phezulu nge-4.7k - 10kohms kwibhodi yomphathi ukuya kwi-voltage ephakathi kwe-2.0V kunye ne-3.6V. I-Logic 0 ibonisa ukusebenza okuqhelekileyo; i-logic 1 ibonisa ukulahleka kwesiginali.
