1.25Gb/s 1310nm Ib hom SFP Transceiver

Lus piav qhia luv luv:

Small Form Factor Pluggable (SFP) transceivers yog sib xws nrog Daim Ntawv Pom Zoo Me Me Pluggable Multi-Sourcing Agreement (MSA). Lub transceiver muaj plaub ntu: tus neeg tsav tsheb LD, lub limiting amplifier, FP laser thiab tus PIN photo-detector. Cov ntaub ntawv module txuas mus txog 20km hauv 9/125um ib hom fiber ntau.

Cov khoom siv kho qhov muag tuaj yeem raug cuam tshuam los ntawm TTL logic qib siab nkag ntawm Tx Disable. Tx Fault yog muab los qhia tias degradation ntawm lub laser. Poob lub teeb liab (LOS) tso zis yog muab los qhia qhov poob ntawm qhov kev tawm tswv yim kho qhov muag ntawm tus txais lossis qhov txuas nrog tus khub.

Nco tseg:
1.Circuit av yog nyob rau hauv cais tawm ntawm chassis av.
2.Laser tso zis tsis taus ntawm TDIS>2.0V lossis qhib, qhib rau TDIS <0.8V.
3.Yuav tsum tau rub nrog 4.7k - 10kohms ntawm lub rooj tsavxwm lub rooj tsavxwm mus rau qhov hluav taws xob ntawm 2.0V thiab 3.6V.MOD_DEF (0) rub kab qis los qhia tias module yog ntsaws rau hauv.
4.Qhov no yog ib qho kev xaiv input siv los tswj cov receiver bandwidth rau compatibility nrog ntau cov ntaub ntawv tus nqi (feem ntau yuav Fiber Channel 1x thiab 2x tus nqi).Yog hais tias siv, cov tswv yim yuav raug rub down nrog> 30kΩ resistor. Cov input states yog:
- Tsawg (0 - 0.8V): Txo Bandwidth
- (> 0.8, < 2.0V): Undefined
- Siab (2.0 - 3.465V): Tag nrho Bandwidth
- Qhib: Txo Bandwidth
5.LOS yog qhib cov khoom tso tawm yuav tsum tau rub nrog 4.7k - 10kohms ntawm lub rooj tsav xwm tswj hwm mus rau qhov hluav taws xob ntawm 2.0V thiab 3.6V. Logic 0 qhia txog kev ua haujlwm ib txwm muaj; logic 1 qhia tias tsis muaj teeb liab.
