DWDM-SFP-3977 Cisco Compatible SFP Transceiver

Spelled out plainly, the DWDM-SFP-3977 is exactly what its Cisco designation reads as: a DWDM transceiver in SFP form. Line side: single-mode fiber (SMF). Faceplate: duplex LC. Management: digital diagnostic monitoring over DDM/DOM, visible to the host platform. On Cisco equipment it registers as the expected part and asks for no setup beyond insertion, taking up its own wavelength within the DWDM scheme while adjacent channels continue unaffected. Nothing else needs decoding: form factor, fiber, connector, and monitoring are the entire published specification set.

• Form Factor: SFP
