The DWDM-XFP-4373-ER-C is a Cisco-compatible 10GBASE-DWDM XFP optical transceiver that delivers up to 40 km reach over single-mode fiber at a fixed 1543.73 nm wavelength.
The module operates at a fixed wavelength of 1543.73 nm (DWDM ITU-T Channel 37) to support 100 GHz channel spacing in dense wavelength division multiplexing networks.
It supports reliable data transmission up to 40 km over standard single-mode fiber (ITU-T G.652) at a 10.3125 Gbps line rate.
This XFP transceiver is compatible with Cisco routers, switches, and optical line cards that support 10G XFP modules and run Cisco IOS or NX-OS with corresponding SFP/XFP firmware.
The module supports single-mode fiber (SMF) compliant with ITU-T G.652 and G.655 standards for long-haul and metro DWDM applications.
It supports 100 GHz (0.8 nm) channel spacing, allowing dense packing of optical channels in DWDM systems.
Transmit power ranges from –5.0 dBm to +2.0 dBm, and receiver sensitivity is typically –24 dBm to ensure error-free performance.
It uses the XFP (10 Gigabit Small Form-Factor Pluggable) form factor, enabling hot-swappable installation in compatible network equipment.
Yes, the module supports hot-plug insertion and removal without powering down the host device, minimizing network downtime.
Yes, it is SFF-8472 compliant and provides real-time monitoring of transmit/receive power, temperature, laser bias current, and supply voltage.
This module operates in the 0 °C to 70 °C ambient temperature range; an extended temperature version (–40 °C to 85 °C) is optionally available.
Yes, it meets RoHS (Restriction of Hazardous Substances) requirements, ensuring environmentally safe materials and manufacturing processes.
Insert the module firmly into the XFP port until it clicks, then verify link status through the device CLI or network management interface.
The module includes a limited lifetime warranty covering manufacturing defects, along with free technical support and RMA services.
Check your device’s transceiver compatibility matrix or Cisco’s hardware installation guide for 10G XFP support and required firmware versions.
The mean time between failures (MTBF) exceeds 1 million hours, providing high reliability for carrier-grade deployments.
We offer a 30-day return window on unopened modules and a 1-year replacement warranty on opened modules in original condition.
