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 mawonekedwe amkati ndizosiyana. Mtengo wa laser DFB ndi wokwera mtengo kwambiri kuposa laser FP. 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 zosiyanasiyana chifukwa cha kudzikundikira kwa mtunda kufala, kuchititsa zimachitika kufalikira motero kulephera kusiyanitsa chizindikiro mtengo.Zigawo ziwirizi makamaka zimakhudza mtunda wotumizira wa module ya kuwala. 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, kuchuluka kwa kufalikira ndi Mphamvu yamagetsi yamagetsi ya Optical module ndi kulandira kumva kudzakhala kosiyana, bola ngati kufala mtunda akhoza kuonetsetsa.

4.Optical module moyo

Miyezo yogwirizana yapadziko lonse lapansi, maola 50,000 ogwira ntchito mosalekeza, maola 50,000 (ofanana ndi zaka 5).

Ma module a SFP Optical onse ndi ma LC interfaces. The GBIC Optical modules onse SC interfaces. Ma interface ena ndi FC ndi ST.
