Optcore 100G SFP 10KM


QSFP28-100G-LR4 is a 100 Gbps Quad Small Form-factor Pluggable QSFP28 optical transceiver for use in 100 Gigabit Ethernet links over 10km single mode fiber. The QSFP28 LR4 transceiver is compliant with the QSFP28 MSA and IEEE 802.3ba

Available on backorder

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


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.
