The Cisco QSFP-100G-ER4L-X Compatible QSFP28 transceiver is designed for use in 100GBASE Ethernet throughput up to 40km over LC duplex SMF using a wavelength of 1310nm. Full 40km reach requires the use of FEC on the host platform. Without FEC, the reach is 30km.
Designed for outside plant applications with an extended temperature range (-20 to 85°C), this transceiver is compliant with SFF-8636 and 4WDM MSA standards. The built-in digital diagnostics monitoring (DDM) allows access to real-time operating parameters. With these features, this easy to install, hot swappable transceiver is suitable for Data Center applications.
