1.25Gb/s 1310nm Single-mode SFP Transceiver

Tsananguro pfupi:

MaSmall Form Factor Pluggable (SFP) transceivers anoenderana neSmall Form Factor Pluggable Multi-Sourcing Agreement (MSA). Transceiver ine zvikamu zvina: LD driver, limiting amplifier, FP laser uye PIN photo-detector. Data remodule rinobatana kusvika 20km mu 9/125um single mode fiber.

Kubuda kwe optical kunogona kudzimwa neTTL logic high-level input yeTx Disable. Tx Fault inopihwa kuratidza kuora kwe laser. Kurasikirwa kwesignal (LOS) output kunopihwa kuratidza kurasikirwa kwe input optical signal ye receiver kana link status ne partner.

Zvinyorwa:
1. Pasi pedenderedzwa rakaparadzaniswa nepasi pechasi.
2. Kubuda kweLaser kwakadzimwa paTDIS >2.0V kana kuvhurika, kwakagoneswa paTDIS <0.8V.
3. Inofanira kudhonzwa kumusoro ne 4.7k - 10kohms pabhodhi remubati kusvika pavoltage iri pakati pe 2.0V ne 3.6V. MOD_DEF (0) inodhonza mutsetse wakaderera kuratidza kuti module yabatanidzwa.
4. Iyi ipfungwa inoshandiswa kudzora bandwidth yemugamuchiri kuti ienderane nemitengo yedata yakawanda (zvichida Fiber Channel 1x ne2x Rates). Kana ikashandiswa, iyo inopinzwa ichadhonzwa mukati ne > 30kΩ resistor. Mamiriro ekupinda ndeaya:
- Yakaderera (0 – 0.8V): Bandwidth Yakaderedzwa
- (>0.8, < 2.0V): Hazvina kutsanangurwa
- Yakakwirira (2.0 – 3.465V): Bandwidth Yakazara
- Yakavhurika: Bandwidth Yakaderedzwa
5. LOS yakavhurika, muunganidzi wemagetsi anofanira kudhonzwa ne 4.7k - 10kohms pabhodhi remugadziri kusvika pavoltage iri pakati pe 2.0V ne 3.6V. Logic 0 inoratidza kushanda kwakajairika; logic 1 inoratidza kurasikirwa kwechiratidzo.
