Kufotokozera Kwachidule:

Mylinking™ RoHS Compliant 1.25Gbps 850nm Optical Transceiver 550m Reach ndi ma module ogwira ntchito bwino komanso otsika mtengo omwe amathandizira kuchuluka kwa deta ya 1.25Gbps ndi mtunda wa 550m wotumizira ndi MMF. Transceiver ili ndi magawo atatu: chotumizira laser cha VCSEL, PIN photodiode yolumikizidwa ndi trans-impedance preamplifier (TIA) ndi unit yowongolera ya MCU. Ma module onse amakwaniritsa zofunikira za chitetezo cha laser cha kalasi I. Ma transceiver amagwirizana ndi SFP Multi-Source Agreement (MSA) ndi SFF-8472. Kuti mudziwe zambiri, chonde onani SFP MSA.

Zolemba:

1. Ngati yakwera kwambiri, mphamvu iyi imasonyeza vuto la laser la mtundu wina. Yotsika imasonyeza ntchito yabwinobwino. Ndipo iyenera kukokedwa ndi choletsa cha 4.7 - 10KΩ pa bolodi la wolandila.

2. TX disable ndi cholowetsa chomwe chimagwiritsidwa ntchito kuzimitsa chotulutsa chowunikira. Chimakokedwa mkati mwa module ndi choletsa cha 4.7 - 10KΩ. Mikhalidwe yake ndi iyi:

Low (0 – 0.8V): Chotumiza chayatsidwa (>0.8, < 2.0V): Chosadziwika

Wapamwamba (2.0V ~ Vcc + 0.3V): Chotumiza Cholemala Kutsegulidwa: Chotumiza Cholemala

3. Mod-Def 0,1,2. Izi ndi ma pin ofotokozera ma module. Ayenera kukokedwa ndi resistor ya 4.7K - 10KΩ pa bolodi la host. Voltage yokoka iyenera kukhala pakati pa 2.0V ~ Vcc + 0.3V.

Mod-Def 0 yakhazikitsidwa ndi module kuti iwonetse kuti moduleyo ilipo

Mod-Def 1 ndi mzere wa wotchi wa mawonekedwe awiri a waya a serial ID

Mod-Def 2 ndi mzere wa data wa ma waya awiri olumikizirana a serial ID

4. Pamene chizindikiro chili pamwamba, chizindikirochi chimasonyeza kutayika kwa chizindikiro (LOS). Chochepa chimasonyeza kuti chizindikirocho chikugwira ntchito bwino.

5. RD+/-: Izi ndi zotulutsa zosinthira. Ndi mizere yosiyana ya AC yolumikizidwa ndi 100Ω yomwe iyenera kuthetsedwa ndi 100Ω (yosiyana) pa SERDES ya wogwiritsa ntchito. Kuphatikiza kwa AC kumachitika mkati mwa module ndipo motero sikofunikira pa bolodi la wolandila.

6. TD+/-: Izi ndi zolowetsa zosinthira zosiyana. Ndi zolumikizidwa ndi AC, mizere yosiyana yokhala ndi 100Ω differential termination mkati mwa module. Kulumikizana kwa AC kumachitika mkati mwa module ndipo motero sikofunikira pa bolodi la host.
