Product Description

Factory supply Qsfp28-100g-10km-Lr4, qsfp 100g 10km  module


This product is a 100Gb/s transceiver module designed for optical communication applications compliant to 100GBASE-LR4 of the IEEE
P802.3ba standard. 

The module converts 4 input channels of 25Gb/s or 27.9GB/s electrical data to 4 channels of LAN WDM optical signals and then multiplexes
them into a single channel for 100Gb/s optical transmission. 

Reversely on the receiver side, the module de-multiplexes a 100Gb/s optical input into 4 channels of LAN WDM optical signals and then converts
them to 4 output channels of electrical data.The central wavelengths of the 4 LAN WDM channels are 1295.56, 1300.05, 1304.58 and 1309.14 nm
