Chosinthira cha SFP cha 1.25Gb/s cha 1310nm cha single-mode

Chithunzi Chodziwika cha 1.25Gb/s 1310nm Single-mode SFP Transceiver

Kufotokozera Kwachidule:

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

Kutulutsa kwa kuwala kumatha kuzimitsidwa ndi TTL logic high-level input ya Tx Disable. Tx Fault imaperekedwa kuti iwonetse kuwonongeka kwa laser. Kutayika kwa chizindikiro (LOS) kumaperekedwa kuti kuwonetse kutayika kwa chizindikiro cholowera cha wolandila kapena momwe chikugwirizana ndi mnzake chikugwirira ntchito.

Zolemba:
1. Dothi la circuit limachotsedwa mkati mwa nthaka ya chassis.
2. Kutulutsa kwa laser kwazimitsidwa pa TDIS >2.0V kapena kutsegulidwa, kwayatsidwa pa TDIS <0.8V.
3. Iyenera kukokedwa ndi 4.7k - 10kohms pa bolodi la host mpaka pa voltage pakati pa 2.0V ndi 3.6V. MOD_DEF (0) imakoka mzere wotsika kuti iwonetse kuti gawo lalumikizidwa.
4. Ichi ndi cholowera chosankha chomwe chimagwiritsidwa ntchito kulamulira bandwidth yolandirira kuti igwirizane ndi mitengo yambiri ya data (mwina Fiber Channel 1x ndi 2x Rates). Ngati chikugwiritsidwa ntchito, choloweracho chidzakokedwa mkati ndi > 30kΩ resistor. Mikhalidwe yolowera ndi iyi:
- Yotsika (0 – 0.8V): Bandwidth Yochepetsedwa
- (>0.8, < 2.0V): Yosadziwika
- Wapamwamba (2.0 – 3.465V): Bandwidth Yonse
- Tsegulani: Bandwidth Yochepetsedwa
5. LOS ndi yotseguka, chotengera chotulutsa chiyenera kukokedwa ndi 4.7k - 10kohms pa bolodi la host mpaka voltage pakati pa 2.0V ndi 3.6V. Logic 0 imasonyeza ntchito yabwinobwino; logic 1 imasonyeza kutayika kwa chizindikiro.
