2.5G GPON C ntxiv rau ntxiv rau SFP 20km
■GPON OLT C ntxiv rau ntxiv yog SFP ntim kub-swappable optical module siv los txuas cov ntaub ntawv sib txuas lus kho qhov muag (raws li ITU-T G.984.x). Nws txais ib qho kev tsim ib leeg-fiber bidirectional, thiab tus nqi uplink thiab downlink tuaj yeem ncav cuag 2.5Gbps. , Siv dav nrog OLT cov cuab yeej ntawm cov khoom lag luam tseem ceeb hauv kev ua lag luam.
■ Ib leeg-fiber bidirectional kub-swappable SFP nrog SC / UPC interface
■ Txog 2.5Gbps kev khiav hauj lwm tus nqi
1490nm DFB-LD transmitter thiab 1310nm tawg hom APD-TIA receiver
■ Txhawb nqa DDM, uas tuaj yeem muab kev kuaj mob thiab kuaj kev ua haujlwm rau lub zog, qhov kub thiab txias, kis tau tus mob thiab tau txais cov xwm txheej, thiab kev pabcuam lub neej.
■ kis tau tus mob mus txog 20KM
■ Ua raws li MSA SFP specification SFF-8472
■ Ua raws li ITU-T G.984.x
