Qaybta 1.Laser-ka
Laysarku waa qaybta dhexe ee ugu muhiimsan moduleka indhaha kaas oo hadda ku duraya walxaha semiconductor oo siiya iftiinka laysarka iyada oo loo marayo dhaqdhaqaaqa sawir-qaadista iyo guulaha godka.Waqtigan xaadirka ah, laser-yada ugu badan ee la isticmaalo waa FP iyo DFB lasers.Farqiga ayaa ah in walxaha semiconductor iyo qaab dhismeedka daloolka ay kala duwan yihiin.Qiimaha laserka DFB aad ayuu uga qaalisan yahay leysarka FP.Qaybaha indhaha ee fogaanta gudbinta ilaa 40KM guud ahaan waxay isticmaalaan leysarka FP;Qaybaha indhaha oo leh masaafada gudbinta ≥40KM guud ahaan waxay isticmaalaan leysarka DFB.
2. Khasaare iyo kala daadsanaan
Khasaaruhu waa luminta tamarta iftiinka sababtoo ah nuugista iyo kala firdhisanaanta dhexdhexaadka ah iyo daadinta iftiinka marka iftiinka lagu kala qaado fiberka.Qaybtan tamarta ka mid ah ayaa lagu kala firdhiyaa heer gaar ah marka masaafada gudbintu ay korodho helitaanka dhamaadka waqtiyo kala duwan sababtoo ah ururinta fogaanta gudbinta, taasoo keentay in garaaca wadnaha balaadhiyo oo sidaas darteed awoodin in la kala saaro qiimaha calaamadaha. Labadan xad waxay inta badan saameeyaan fogaanta gudbinta ee moduleka indhaha.Habka codsiga dhabta ah, 1310nm moduleka indhaha guud ahaan wuxuu xisaabiyaa khasaaraha isku xirka 0.35dBm/km, iyo 1550nm moduleka indhaha guud ahaan wuxuu xisaabiyaa khasaaraha isku xirka .20dBm / km, wuxuuna xisaabiyaa qiimaha kala firidhsan.Aad u adag, guud ahaan kaliya tixraac.
3.Transmitted power power and helitaanka dareenka
Awoodda indhaha ee la kala qaado waxaa loola jeedaa soosaarka awoodda indhaha ee isha iftiinka ee dhamaadka gudbinta ee moduleka indhaha.Dareenka helitaanka waxa loola jeedaa ugu yar ee la helay awoodda indhaha ee moduleka indhaha ee heer go'an iyo xoogaa khalad ah.Halbeegyada labadan cabbir waa dBm (macnaha decibel milliwatt, logarithm unugga awoodda mw, qaacidada xisaabinta waa 10lg, 1mw waxaa loo rogaa 0dBm), taas oo inta badan loo isticmaalo in lagu qeexo fogaanta gudbinta ee alaabta, hirarka kala duwan. heerka gudbinta iyo Awoodda gudbinta indhaha ee moduleka indhaha iyo helitaanka dareenka way ka duwanaan doontaa, ilaa inta fogaanta gudbinta la hubin karo.
4. nolosha module indhaha
Heerarka caalamiga ah ee midaysan, 50,000 saacadood oo shaqo joogto ah, 50,000 saacadood (oo u dhiganta 5 sano).
Qaybaha indhaha ee SFP waa dhammaan LC interfaces.Qaybaha indhaha ee GBIC waa dhammaan SC interfaces.Isku xirka kale waxaa ka mid ah FC iyo ST.
