I-Optical Module

1.25Gbps 550m Duplex LC SFP Transceiver

Incazelo

Siyajabula ukwethula amamojula e-SFP ekhwalithi ephezulu, athengekayo aklanyelwe ukusekela amanani edatha we-1.25Gbps namabanga okudlulisela amamitha angu-550 ngaphezu kwe-multimode fiber (MMF). I-transceiver ihambisana ngokugcwele ne-SFP Multi-Source Agreement (MSA) kanye namazinga e-SFF-8472. Ukuze uthole imininingwane eyengeziwe, bheka imibhalo ye-SFP MSA kanye ne-SFF-8472.

Sikholelwa ukuthi amamojula wethu we-SFP optical azohlangabezana futhi adlule okulindele ekusebenzeni nokuthembeka. Uma unemibuzo noma ungathanda ukuxoxa ngezidingo zakho ezithile, sicela ukhululeke ukusithinta.

Siyabonga ngokucabangela imikhiqizo yethu.

Amanothi:

1. Xhuma ngqo kuphinikhodi yokufaka idatha ye-TX. Ukuhlangana kwe-AC kusuka kuphini kuya kumshayeli we-laser IC.

2. I-LOS iwukuphuma komqoqi ovulekile. Kufanele idonswe ebhodini lomama ngo-4.7kΩ - 10kΩ. I-Logic 0 yokusebenza okuvamile; i-logic 1 yokulahlekelwa kwesignali.
