100G QSFP28 LR4 Fiber Transceiver Module
LC 10km Fiber Optic Transceiver 100G Base LR4 QSFP28 SM 1310nm 4 LAN WDM Channels
Description
Cisco Compatible 100G Base LR4 QSFP28 SM 1310nm LC 10km Transceiver Module manufactured by ANC International Co., Limited is a 100Gb/s transceiver module designed for optical communication applications compliant to 100GBASE-LR4 of the IEEE 802.3ba standard. The module converts 4 input channels of 25Gb/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 as members of the LAN WDM wavelength grid defined in IEEE 802.3ba. The high performance cooled LAN WDM DFB transmitters and high sensitivity PIN receivers provide superior performance for 100Gigabit Ethernet applications up to 10km links and compliant to optical interface with 100GBASE-LR4 requirements specified in IEEE 802.3ba Clause 88.
The product is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP+ Multi-Source Agreement (MSA). It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference.
