Key Features of LINK-PP LS-DW3910-80C 10G SFP+
LINK-PP LS-DW3910-80C is a commercial-grade 10G SFP+ DWDM optical transceiver module designed to deliver stable 10Gbps data transmission over 80km single-mode fiber links. It integrates a 1546.12nm (C39) wavelength design, a duplex LC optical interface, and built-in digital diagnostic monitoring into an MSA-compliant footprint.
LINK-PP LS-DW3910-80C 10G SFP+ Optical Module
The hot-pluggable SFP+ footprint allows seamless field installation and maintenance without disrupting host switch operations. Full compliance with the SFP+ Multi-Source Agreement (MSA) ensures broad physical and electrical compatibility across standard networking hardware.
LS-DW3910-80C: 10 Gbps Connectivity for Metro Ethernet Networks
A dedicated line rate of 10Gbps provides ample data throughput to satisfy heavy bandwidth demands across regional aggregation layers. This makes the module well-suited for scaling urban metro Ethernet networks and point-to-point enterprise links.
LS-DW3910-80C Module with DWDM Technology for Fiber Efficiency
Dense Wavelength Division Multiplexing (DWDM) technology enables multiple independent optical channels to transmit over a single pair of dark fiber. This architecture maximizes existing cable infrastructure capacity while significantly lowering fiber leasing and operational costs.
LS-DW3910-80C Module with 1546.12nm Wavelength
The fixed 1546.12nm central wavelength operates precisely on the standardized 100GHz ITU-T C-Band optical grid (Channel 39). Cooled laser technology guarantees narrow spectral line width and minimal wavelength drift across standard operating conditions.
LS-DW3910-80C Module Supporting 80km Transmission
An advanced cooled EML laser coupled with a high-sensitivity APD receiver provides the optical link budget required for long-range 80km transport. This capability reliably spans extended distances without requiring inline optical amplifiers.
LS-DW3910-80C Module with Duplex LC Interface
The industry-standard duplex LC optical receptacle enables quick, secure mating with standard single-mode fiber patch cables. Precision internal optical alignment minimizes insertion loss while maintaining optimal return loss over repeated mating cycles.
