The LINK-PP LS-DW291G-80C is a 1G DWDM SFP optical transceiver engineered for 1.25Gbps data transmission. Designed with a hot-swappable SFP form factor, this module follows the 100GHz ITU channel grid and includes an integrated wavelength locker to stabilize wavelength performance, supporting up to 80km signal transmission across single-mode fiber (SMF).It meets SFP MSA and SFF-8472 specifications and is fitted with a duplex LC connector interface. Equipped with a DWDM EML laser transmitter and PIN photodetector, the transceiver operates from a single +3.3V power rail and offers real-time digital diagnostic monitoring (DDM) for status tracking. RoHS certified, this DWDM SFP module is a reliable solution for long-haul DWDM fiber networking deployments.
