Netgear DWDM-SFP10G-39.77-I Compatible LINK-PP DWDM SFP+ optical transceiver provides 10Gbps data transmission over single-mode fiber using fixed DWDM channels. It allows network operators to maximize fiber usage, cover distances up to 80km, and track link health with built-in digital diagnostics.
The module utilizes a hot-pluggable SFP+ footprint that simplifies field maintenance and allows module replacement without interrupting host system operations. Fully compliant with SFP+ MSA specifications, it runs on a single +3.3V power supply to ensure straightforward hardware integration across standard switch ports.
Data transmission supports line rates up to 10.7Gbps to provide consistent throughput across extended fiber links. This 10Gbps capability reliably handles demanding optical traffic between regional metro aggregation sites and long-haul transport routes.
Dense wavelength division multiplexing allows multiple independent optical channels to transmit over a single physical single-mode fiber link. By combining distinct data streams onto shared fiber strands, this approach significantly multiplies overall link capacity without deploying additional cabling.
Optical transmission operates at an exact 1539.76nm center wavelength corresponding to Channel C47 on the standard DWDM grid. This tight wavelength precision maintains clean optical channel isolation and prevents adjacent-channel crosstalk inside optical multiplexers and demultiplexers.
An integrated cooled EML transmitter and APD receiver deliver the required optical link budget to transmit signals across single-mode fiber distances up to 80km. This physical-layer setup maintains sufficient signal clarity over long spans to eliminate the need for intermediate optical amplifiers in point-to-point runs
Equipped with an industry-standard duplex LC optical receptacle, the module easily connects to existing fiber infrastructure with a secure latching mechanism. It provides separate transmit and receive channels with minimal insertion loss, making cable management clean and dependable in crowded racks.
Integrated digital diagnostic monitoring gives technicians immediate visibility into critical operating variables such as TX/RX optical power, module temperature, supply voltage, and laser bias current. Continuous reporting of these physical-layer metrics helps isolate link anomalies promptly and supports proactive network troubleshooting.
