1.25G SFP EPON PX20 ntxiv rau ntxiv
■PON OLT PX20 ntxiv rau PX20 ntxiv rau PX20 ntxiv rau ntxiv yog ib qho SFP ntim kub-swappable optical module (raws li IEEE 802.3ah 1000BASE-PX20 ntxiv) siv los txuas cov ntaub ntawv sib txuas lus kho qhov muag. Nws txais ib qho kev tsim ib leeg-fiber bidirectional, thiab tus nqi uplink thiab downlink tuaj yeem ncav cuag 1.25Gbps, uas yog dav siv nrog kev ua lag luam. Mainstream hom OLT khoom.
■ Ib leeg-fiber bidirectional kub-swappable SFP nrog SC / UPC interface
■ Txog 1.25Gbps 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 IEEE 802.3ah
