Transceiver ya SFP ya 1.25Gb/s ya 1310nm imwe

Ishusho ya 1.25Gb/s 1310nm SFP Transceiver ifite uburyo bumwe

Ibisobanuro bigufi:

Transceivers za Small Form Factor Pluggable (SFP) zirahuye na Small Form Factor Pluggable Multi-Sourcing Agreement (MSA). Transceiver igizwe n'ibice bine: LD driver, limiting amplifier, FP laser na PIN photo-detector. Amakuru ya module ahuza uburebure bwa kilometero 20 muri fibre ya 9/125um single mode.

Umusaruro w'urumuri ushobora guhagarara hakoreshejwe uburyo bwo hejuru bwa TTL logic bwa Tx Disable. Ikosa rya Tx ritangwa kugira ngo rigaragaze ko laser yangiritse. Umusaruro w'urumuri (LOS) utangwa kugira ngo ugaragaze ko ikimenyetso cy'urumuri cyangiritse cyangwa imiterere y'urumuri n'umufatanyabikorwa.

Inyandiko:
1. Ubutaka bw'uruziga butandukanijwe imbere n'ubutaka bwa chassis.
2. Umusaruro wa laser wafunzwe kuri TDIS >2.0V cyangwa ufunguye, ufunguwe kuri TDIS <0.8V.
3. Igomba gukururwa na 4.7k - 10kohms ku kibaho cy’umuyoboro w’amashanyarazi kugeza kuri voltage iri hagati ya 2.0V na 3.6V. MOD_DEF (0) irakurura umurongo wo hasi kugira ngo yerekane ko module ifunguye.
4. Iyi ni uburyo bwo kwinjira bukoreshwa mu kugenzura umuyoboro wa receiver kugira ngo uhuze n'ibipimo byinshi by'amakuru (bishoboka cyane ko ari Fiber Channel 1x na 2x Rates). Iyo bishyizwe mu bikorwa, kwinjira bizakurwa imbere hakoreshejwe resistor ya > 30kΩ. Imiterere y'uburyo bwo kwinjira ni iyi:
- Hasi (0 – 0.8V): Umurambararo wagabanutse
- (>0.8, < 2.0V): Ntibisobanutse neza
- Hejuru (2.0 – 3.465V): Bandwidth yuzuye
- Ifunguye: Igabanuka ry'umuvuduko w'amakuru (bandwidth)
5. Isoko ry'umuyoboro wa LOS rifunguye rigomba gukururwa na 4.7k - 10kohms ku kibaho cy'umuyoboro kugeza kuri voltage iri hagati ya 2.0V na 3.6V. Isoko rya 0 rigaragaza imikorere isanzwe; isoko rya 1 rigaragaza igihombo cy'ikimenyetso.
