Module ya Mylinking™ Optical Transceiver SFP LC-MM 850nm 550m

ML-SFP-MX 1.25Gbps SFP 850nm 550m LC Multi-Mode

Ibisobanuro bigufi:

Mylinking™ RoHS Compliant 1.25Gbps 850nm Optical Transceiver 550m Reach ni modules zikora neza kandi zihendutse zishyigikira igipimo cy'amakuru cya 1.25Gbps n'intera yo kohereza kuri MMF ya 550m. Transceiver igizwe n'ibice bitatu: VCSEL laser transmitter, PIN photodiode ihujwe na trans-impedance preamplifier (TIA) na MCU control unit. Modules zose zujuje ibisabwa mu rwego rwa mbere mu bijyanye n'umutekano wa laser. Transceivers zijyanye na SFP Multi-Source Agreement (MSA) na SFF-8472. Kugira ngo ubone amakuru arambuye, reba SFP MSA.

Inyandiko:

1. Iyo iri hejuru, iyi output igaragaza ikosa rya laser ry'ubwoko runaka. Iri hasi igaragaza imikorere isanzwe. Kandi igomba gukururwa na resistor ya 4.7 - 10KΩ ku kibaho cy'umuyoboro.

2. TX disable ni uburyo bwo kwinjira bukoreshwa mu kuzimya umusaruro wa transmitter optique. Bukururwa muri module hamwe na resistor ya 4.7 - 10KΩ. Imiterere yabwo ni iyi:

Hasi (0 – 0.8V): Itumanaho riri kuri (>0.8, < 2.0V): Ntirisobanutse neza

Hejuru (2.0V ~ Vcc + 0.3V): Imashini itwara ubutumwa yafunguye: Imashini itwara ubutumwa yafunguye

3. Mod-Def 0,1,2. Izi ni pin zo gusobanura module. Zigomba gukururwa hakoreshejwe resistor ya 4.7K – 10KΩ ku kibaho cy’umuyoboro. Voltage yo gukurura igomba kuba hagati ya 2.0V ~ Vcc + 0.3V.

Mod-Def 0 yashingiweho na module kugira ngo igaragaze ko module ihari

Mod-Def 1 ni umurongo w'isaha w'umurongo w'insinga ebyiri w'uruhererekane rw'indangamuntu y'uruhererekane

Mod-Def 2 ni umurongo w'amakuru w'insinga ebyiri zihuza serial interface kuri serial ID

4. Iyo ari hejuru, uyu musaruro ugaragaza ko ikimenyetso cyatakaye (LOS). Hafi ugaragaza imikorere isanzwe.

5. RD+/-: Izi ni zo mashini zitanga amashanyarazi zijyanye n'uburyo bwo kwakira amakuru. Ni imirongo ihuza amashanyarazi ya 100Ω igomba guhagarara hamwe na 100Ω (itandukaniro) kuri SERDES y'umukoresha. Guhuza amashanyarazi byakorewe muri module bityo ntibikenewe ku rubuga rwakira amakuru.

6. TD+/-: Ibi ni ibikoresho byo kohereza amakuru bitandukanya. Ni imirongo ihuza AC, ifite iherezo rya 100Ω ry'itandukaniro muri module. Guhuza AC bikorerwa muri module bityo ntibikenewe ku rubuga rwa host.
