DWDM-SFP-3819 Cisco Compatible SFP Transceiver

The title is the datasheet in miniature: DWDM-SFP-3819, Cisco-compatible, DWDM, SFP. In practice that means a module that seats in a Cisco SFP port coded for this part number, runs single-mode fiber (SMF) through a duplex LC connector, and reports DDM/DOM readings while in service. It takes one wavelength assignment inside a Cisco DWDM channel plan and holds it, with recognition by the host handled automatically at insertion. The swap routine is correspondingly short: seat the module, confirm light, move on.
