Optical Module

1.25Gbps 550m Duplex LC SFP Transceiver

Tlhaloso

Re thabela ho hlahisa li-module tsa SFP optical tsa boleng bo phahameng, tse theko e tlaase tse etselitsoeng ho tšehetsa litekanyetso tsa data tsa 1.25Gbps le libaka tsa phetisetso ea limithara tse 550 holim'a fiber ea multimode (MMF). Transceiver e lumellana ka botlalo le SFP Multi-Source Agreement (MSA) le litekanyetso tsa SFF-8472. Bakeng sa lintlha tse ling, bona litokomane tsa SFP MSA le SFF-8472.

Re lumela hore li-module tsa rona tsa SFP Optical li tla kopana le ho feta litebello tsa hau tsa ts'ebetso le ts'epahalo. Haeba u na le lipotso kapa u lakatsa ho bua ka litlhoko tsa hau tse ikhethileng, ka kopo ikutloe u lokolohile ho ikopanya le rona.

Rea leboha ha u nahanne ka lihlahisoa tsa rona.
