Singlemode 10G SFP + BiDi Wdm 40km hamwe na DDM SFP transceiver

1. TX Ikosa nigisohoka gifungura icyegeranyo, kigomba gukururwa hamwe na 4.7k ~ 10kΩ résistor ku kibaho cyakiriye kuri voltage.

hagati ya 2.0V na Vcc + 0.3V. Logic 0 yerekana imikorere isanzwe; logique 1 yerekana lazeri ikosa ryubwoko runaka. Muri leta yo hasi,

ibisohoka bizakwega munsi ya 0.8V.

2. TX Disable niyinjiza ikoreshwa muguhagarika transmitter optique isohoka. Ikururwa muri temodule

hamwe na 4.7k ~ 10kΩ. Ibihugu byayo ni:

Hasi (0 ~ 0.8V): Kohereza kuri
(> 0.8V, <2.0V): Ntisobanuwe
Hejuru (2.0 ~ 3.465V): Ikwirakwiza ryahagaritswe
Fungura: Ikwirakwizwa ryahagaritswe
3. MOD-DEF 0,1,2 nibisobanuro byerekana module. Bagomba gukururwa hamwe na 4.7k ~ 10kΩ résistoriste kuri
Ikibaho. Umuvuduko ukurura ugomba kuba VccT cyangwa VccR.
MOD-DEF 0 ishingiye kuri module kugirango yerekane ko module ihari
MOD-DEF 1 numurongo wisaha yibice bibiri byuruhererekane rwindangamuntu
MOD-DEF 2 numurongo wamakuru wibice bibiri byuruhererekane rwindangamuntu
4. LOS nigisohoka gifungura ibicuruzwa, bigomba gukururwa hamwe na 4.7k ~ 10kΩ résistor ku kibaho cyakira kuri voltage.

hagati ya 2.0 na Vcc + 0.3V. Logic 0 yerekana imikorere isanzwe; logique 1 yerekana gutakaza ibimenyetso. Muri Leta yo hasi ,.

ibisohoka bizakururwa kugeza munsi ya 0.8V.

5. Ibi nibisohoka bitandukanye byakira. Ni imbere AC-ihujwe 100Ω imirongo itandukanye igomba guhagarikwa

hamwe 100Ω (itandukaniro) kumukoresha SERDES.
6. Izi ninyandiko zinyuranye zohereza. Ni AC-ihujwe, imirongo itandukanye hamwe 100Ω itandukanyirizo imbere muri module.
