Koj puas tau ntsib qhov teeb meem uas qhov txuas tsis tuaj yeem tshwm sim thaum 1310nm optical module kis tau ntawm G.655 optical fiber? Kuv ntsib qhov teeb meem no tsis ntev los no, thiab tam sim no kuv xav qhia rau koj.
Cov tsos mob ua tsis tiav
Module:100G QSFP281310nm 80km optical transceiver
Hloov: Cisco NCS540
Optical fiber ntau: G.655, nrug 50km
Cov tsos mob ua tsis tiav: Kev sib txuas tsis tuaj yeem nce mus.
Kev tsom xam:
1.Hloov lwm tus hloov, qhov txuas txuas ntxiv nrov plig plawg
2.Siv G.652 optical fiber test hauv lab, Link ua haujlwm ok. Optical module Tx zog thiab Rx zog yog nyob rau hauv spec. Qhov ntawd txhais tau tias optical transceivers kev ua tau zoo yog ok.
3.DWDM optical modules ua haujlwm zoo ntawm G.655 txuas, uas txhais tau tias G.655 txuas tsis tawg.
4.Deduce: Optical module wavelength thiab fiber ntau tsis phim
Keeb kwm:
Optical modulesnrog rau kev ua haujlwm wavelength ntawm 1310nm tsis tuaj yeem siv G.655 optical fiber ntau rau kev sib kis mus ntev, G.655 Optical cable cutoff wavelength Tsawg dua lossis sib npaug rau 1480nm, qhov rais ua haujlwm yog C band thiab L band (1530nm ~ 1625nm), uas txhais tau tias yog wavelength me dua 1480nm, siv tsis tau ntawm G.655
Cov ntsiab lus:
1. G.655 optical fiber tsis tuaj yeem xa tawm 1310 nm cov cim vim tias qhov kev txiav tawm wavelength ntawm G.655 optical fiber yog 1480 nm.
2. Yog hais tias lub hwj chim input thiab txais lub hwj chim yog ib txwm tab sis qhov txuas tsis tuaj yeem nce, nws feem ntau yog vim tias hom optical module tsis phim hom fiber ntau.
