1.Laser gulu
Laser ndiye gawo lapakati kwambiri la module ya optical yomwe imalowetsa panopa mu semiconductor material ndi kutulutsa kuwala kwa laser kupyolera mu photon oscillations ndikupindula muzitsulo.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 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 losafanana 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 likhale lokulitsa ndipo motero kulephera kusiyanitsa mtengo wa zizindikiro.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 unit mphamvu mw, chiŵerengero chowerengera ndi 10lg, 1mw chimasinthidwa kukhala 0dBm), chomwe chimagwiritsidwa ntchito kutanthauzira mtunda wotumizira mankhwala, mafunde osiyanasiyana, 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).
Ma module a SFP Optical onse ndi ma LC interfaces.The GBIC Optical modules onse SC interfaces.Ma interface ena ndi FC ndi ST.
