DWDM-XENPAK-39.77 — Cisco SFP

The DWDM-XENPAK-39.77 is a Cisco DWDM XENPAK form factor transceiver, designed for 10 Gigabit Ethernet interfaces on first-generation Cisco 10G equipment. This larger form factor, the precursor to X2 and XFP, is still found on many platforms in active production. It operates on a dedicated channel of the DWDM grid, with no wavelength specified in the provided data.

Its primary use case is the maintenance and capacity upgrade of existing infrastructure based on Cisco XENPAK chassis, particularly in metropolitan transport networks. Cisco authenticity ensures full compatibility and manufacturer support. Genuine Cisco module, manufacturer warranty.
