The Cisco QSFP-100G-4W40-I= is a high-performance 100G QSFP28 transceiver designed for 4WDM-40 applications. It supports link lengths of up to 40km over a standard pair of G.652 single-mode fiber (SMF) using duplex LC connectors. This module is engineered for industrial temperature ranges, making it suitable for deployments in harsh environments such as outdoor cabinets and unconditioned data center spaces. The 100 Gigabit Ethernet signal is carried over four wavelengths (1295nm, 1300nm, 1304nm, and 1309nm), with multiplexing and demultiplexing managed within the device. Full 40km reach requires the use of Forward Error Correction (FEC) on the host platform; without FEC, the reach is 30km. It is backward compatible with Cisco's CPAK ER4-Lite and IEEE 100GBASE-ER4 standard transceivers.
