DWDM-SFP-4056 Cisco Compatible SFP Transceiver

The DWDM-SFP-4056 carries Cisco coding. Its build is the standard DWDM SFP arrangement: an SMF line interface, a duplex LC connector, and DDM/DOM telemetry for in-service monitoring. Deployed at one wavelength position in a Cisco DWDM system, it interoperates with the rest of the channel plan as the design intends. Where documentation matters, the module reports itself under this same part number, keeping audits and inventories consistent.
