Cisco compatible QSFP-100G-4W40 Description
EdgeOptic's QSFP-100G-4W40 compatible is a Cisco-coded 100GBASE-4WDM-40 QSFP28 transceiver built to the 4WDM-40 MSA. It mirrors Cisco part QSFP-100G-4W40 for 100 Gigabit Ethernet links up to 40 km on a single duplex pair of G.652 single-mode fiber, with host-side RS-FEC required for the full reach.
Optical layer uses four LAN-WDM channels at 1295.56, 1300.05, 1304.58, and 1309.14 nm, each carrying 25.78125 Gb/s NRZ. Cooled EML transmitters land between -2 dBm and +4 dBm per lane, and APD receivers reach -21 dBm sensitivity with -1 dBm overload. Optical link budget is 22 dB with host RS-FEC engaged for the full 40 km reach, or 18 dB without FEC. Host RS-FEC is required for the 40 km application.
Protocol scope is 100GE only. The 4WDM-40 MSA defines a 100GBASE application with KR4 FEC and does not extend to OTU4 or Fibre Channel. Use this module for 100GBASE-4WDM-40 ports only; OTU4 transponder applications on the same root family are served by separate SKUs.
Compatible with Cisco NCS 5500 and NCS 5700 series systems with QSFP28 ports running IOS XR, as well as other Cisco platforms with 100GBASE-4WDM-40 support per Cisco product documentation. Verify the specific line card or port-cage entry against the Cisco TMG matrix and the chassis transceiver table before deployment, particularly for IOS XR releases that gate 100GBASE-4WDM-40 host-FEC support.
EEPROM is programmed with Cisco-recognized vendor data, so the optic comes up cleanly on IOS XR and NX-OS without the service unsupported-transceiver command and with no third-party-transceiver warning at the CLI. DOM is supported through the standard QSFP28 SFF-8636 page map. Form factor is QSFP28 duplex LC PC/UPC; module power 4.5 W maximum; commercial operating temperature 0 to +70 C.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty included. For Cisco platform validation against your IOS XR or NX-OS release, contact our sales team.
