Singlemode 10G SFP+ BiDi Wdm 40km yokhala ndi transceiver ya DDM SFP

1. TX Fault ndi chotulutsa chotseguka, chomwe chiyenera kukokedwa ndi 4.7k ~ 10kΩ resistor pa bolodi lokhala nawo ku voteji.

pakati pa 2.0V ndi Vcc+0.3V. Logic 0 imasonyeza ntchito yachibadwa; logic 1 imasonyeza vuto la laser la mtundu wina. M'malo otsika,

linanena bungwe adzakhala anakokera ku zosakwana 0.8V.

2. TX Disable ndi cholowetsa chomwe chimagwiritsidwa ntchito kutseka ma transmitter optical output. Imakokedwa mkati mwa module

ndi 4.7k ~ 10kΩ resistor. Makhalidwe ake ndi awa:

Pansi (0~0.8V): Transmitter pa
(> 0.8V, <2.0V): Zosadziwika
Pamwamba (2.0 ~ 3.465V): Transmitter Wolemala
Tsegulani: Transmitter Yayimitsidwa
3. MOD-DEF 0,1,2 ndi zikhomo zotanthauzira gawo. Ayenera kukokedwa ndi 4.7k ~ 10kΩ resistor
gulu la alendo. Mphamvu yamagetsi iyenera kukhala VccT kapena VccR.
MOD-DEF 0 imakhazikitsidwa ndi gawo kusonyeza kuti gawoli liripo
MOD-DEF 1 ndi mzere wa wotchi wa mawonekedwe awiri a waya wa serial ID
MOD-DEF 2 ndi mzere wa data wamawaya awiri amtundu wa serial ID
4. LOS ndi kutuluka kwa osonkhanitsa otseguka, komwe kumayenera kukokedwa ndi 4.7k ~ 10kΩ resistor pa bolodi la alendo kuti likhale ndi magetsi.

pakati pa2.0Vand Vcc+0.3V. Logic 0 imasonyeza ntchito yachibadwa; logic 1 ikuwonetsa kutayika kwa chizindikiro. M'malo otsika, a

zotulutsa zidzakokedwa mpaka zosakwana 0.8V.

5. Izi ndizosiyana zolandirira. Ndi mizere yosiyana ya AC-ophatikizana 100Ω yomwe iyenera kuthetsedwa

ndi 100Ω (zosiyana) pa wogwiritsa SERDES.
6. Izi ndi zolowetsa ma transmitter osiyanasiyana. Iwo ndi AC-ophatikizana, mizere yosiyana ndi 100Ω kusiyana pakati pa gawo.
