Applications
The 100G QSFP28 ERL 4x 25G NRZ QSFP-100G-ERL-S 1310nm 25km Duplex LC/UPC Single Lambda Module, Cisco is used in 100G Ethernet, data center interconnect and 5G transport networks, where it provides a 106.25Gbps link over SMF up to 25km. With its Duplex LC optical interface, the module works directly with the SMF infrastructure already installed in most facilities. It is interoperable with Cisco platforms and replaces the Cisco part QSFP-100G-ERL-S directly.
Standards and Compatibility
