SKU: STI-QSFP28-100G-LR4 Category:


The QSFP28 LR4 transceiver is compliant with the QSFP28 MSA and IEEE 802.3ba. The transceiver 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. On the receiver side, the transceiver 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 QSFP28-100G-LR4 transceiver optics uses an MSA compliant 38 pin edge type connector on the electrical interface and uses a duplex LC connector on optical interface. The QSFP28 LR4 optical transceiver has built-in DDM functions per QSFP28 MSA, which allows real-time access to the following operating parameters: transceiver temperature, laser bias current, transmitted optical power, received optical power and transceiver supply voltage.
