DWDM-XENPAK-43.73 — Cisco SFP

The DWDM-XENPAK-43.73 is a Cisco XENPAK format transceiver designed for DWDM applications on long-haul single-mode fiber. This module operates on a dedicated channel of the DWDM grid; no wavelength value is available in the provided product specifications. The XENPAK form factor, larger than the SFP, is suited to earlier-generation Cisco equipment that requires this specific form factor.

Perfect for modernizing existing optical networks based on XENPAK-compatible Cisco platforms, this module ensures reliable DWDM transmission over long-reach infrastructures. It targets network teams looking to maintain or extend high-capacity WAN links. Genuine Cisco hardware, compatible with certified equipment.
