QSFP28 Optical Transceivers 100GBASE Ethernet LWDM4 20KM LH4 for Data Center
QSFP28 Optical Transceivers
Feature of TQSFP28-100G-LH4
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 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.
TQSFP28-100G-LH4
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 EA-DFB transmitters and high sensitivity PIN receivers provide superior performance for 100Gigabit Ethernet applications up to 20km links and compliant to optical interface with IEEE802.3ba Clause 88 100GBASE-LR4 requirements.
