1.Laser gulu
Laser ndiye gawo lapakati kwambiri la module ya optical yomwe imalowetsa pano mu semiconductor material ndipo imatulutsa kuwala kwa laser kudzera pa photon oscillations ndikupindula m'mimba. Pakadali pano, ma laser omwe amagwiritsidwa ntchito kwambiri ndi FP ndi DFB lasers. Kusiyana kwake ndikuti zida za semiconductor ndi kapangidwe ka patsekeke ndizosiyana. Mtengo wa laser DFB ndi wokwera mtengo kwambiri kuposa FP laser. Ma module a kuwala okhala ndi mtunda wofikira mpaka 40KM nthawi zambiri amagwiritsa ntchito ma laser a FP; ma module okhala ndi mtunda wotumizira ≥40KM nthawi zambiri amagwiritsa ntchito ma laser a DFB.
2.Kutayika ndi kubalalitsidwa
Kutayika ndiko kutayika kwa mphamvu ya kuwala chifukwa cha kuyamwa ndi kubalalika kwa sing'anga ndi kutuluka kwa kuwala pamene kuwala kumafalikira mu fiber. Mbali iyi ya mphamvu imatayidwa pamlingo wina pamene mtunda wotumizira ukuwonjezeka.Kubalalika kumachitika makamaka chifukwa cha liwiro losagwirizana la mafunde a electromagnetic a mafunde osiyanasiyana omwe amafalikira mu sing'anga yomweyo, zomwe zimapangitsa kuti zigawo za kutalika kwa mawonekedwe a kuwala zifike kulandira mapeto pa nthawi zosiyana chifukwa cha kudzikundikira kwa mtunda wotumizira, zomwe zimapangitsa kuti phokoso liwonjezeke ndipo motero kulephera kusiyanitsa chizindikiro cha mtengo. Munjira yeniyeni yogwiritsira ntchito, 1310nm Optical module nthawi zambiri imawerengera kutayika kwa ulalo pa 0.35dBm/km, ndipo 1550nm Optical module nthawi zambiri imawerengera kutayika kwa ulalo pa .20dBm/km, ndikuwerengera mtengo wobalalika. Zovuta kwambiri, nthawi zambiri zimangotanthauza.
3.Kutumiza mphamvu ya kuwala ndi kulandira kumva
Mphamvu yamagetsi yopatsirana imatanthawuza mphamvu yotulutsa kuwala kwa gwero la kuwala kumapeto kwa gawo la optical module. Kuzindikira kolandirira kumatanthawuza mphamvu yochepera yolandirira ya Optical module pamlingo wina ndi kulakwitsa pang'ono. Magawo a magawo awiriwa ndi dBm (kutanthauza decibel milliwatt, logarithm ya mphamvu yamagetsi mw, chiŵerengero cha mawerengedwe ndi 10lg, 1mw chimasinthidwa kukhala 0dBm), chomwe chimagwiritsidwa ntchito makamaka kutanthauzira mtunda wotumizira mankhwala, kutalika kwake kosiyana, mlingo kufala ndi The kuwala module wa kuwala kufalitsa mphamvu ndi kulandira tilinazo adzakhala osiyana, bola kufala mtunda angatsimikizidwe.
4.Optical module moyo
Miyezo yogwirizana yapadziko lonse lapansi, maola 50,000 ogwira ntchito mosalekeza, maola 50,000 (ofanana ndi zaka 5).
The SFP Optical modules onse ndi LC interfaces. Ma module a GBIC Optical onse ndi SC interfaces. Ma interface ena ndi FC ndi ST.
