Netgear CWDM-SFP-1390 Compatible LINK-PP module is a commercial-grade 1390nm CWDM SFP transceiver that bundles the essential capabilities for dependable long-haul fiber links. It integrates a 1Gbps data rate, 80km reach, SFP MSA compliance, duplex LC connectivity, and real-time DOM, all within a hot-pluggable mechanical design.
The hot-pluggable SFP footprint of this module allows field replacement without interrupting system operation. Its full compliance with the SFP MSA ensures seamless interoperability with a wide range of standard host equipment.
CWDM-SFP-1390: 1 Gbps Connectivity for Enterprise Fiber Infrastructures
For enterprise fiber infrastructures, this SFP module supplies a clean 1Gbps transport channel, bridging various network segments from the main data center to wiring closets. Its bandwidth is more than adequate for day-to-day enterprise data exchanges and end-user connectivity needs.
CWDM-SFP-1390 Module with CWDM Technology for Fiber Efficiency
CWDM technology in this module maximises fibre utilisation by multiplexing several independent channels onto a single fibre pair. Operating on a designated CWDM grid channel, it reduces the number of physical fibres needed for network expansion.
CWDM-SFP-1390 Module with 1390nm Wavelength
The 1390nm channel offers low attenuation in standard single-mode fibre and maintains moderate dispersion over extended distances. This wavelength fits neatly into common CWDM plans, providing a cost-effective choice for metro and regional networks.
CWDM-SFP-1390 Module Supporting 80km Transmission
80km reach is achieved through a DFB laser transmitter and a sensitive PIN photodiode receiver, which together supply sufficient optical budget for the link. Such distance covers most city-wide connections and long campus backbones without requiring intermediate regeneration.
CWDM-SFP-1390 Module with Duplex LC Interface
Equipped with a duplex LC optical connector, this module offers a familiar and reliable interface for fiber patch cords and panels. The LC design ensures low insertion loss and easy polarity management, making it convenient for high-density wiring environments.
CWDM-SFP-1390 Module with DOM for Real-Time Monitoring
Real-time DOM gives network operators instant visibility into transmit/receive optical power, laser bias current, temperature, and supply voltage. These live measurements help detect early signs of fibre degradation and enable proactive maintenance before link failures occur.
The CWDM-SFP-1390 1G SFP transceiver meets strict global safety and environmental standards, including ISO 9001, CE, RoHS, and FCC. It gives network operators peace of mind regarding product quality and regulatory compliance.
Each module goes through rigorous factory checks to test optical performance and signal stability under different temperatures. This ensures durable operation before reaching the customer.

Installed a batch in a managed network supporting remote access cabinets connected back to an indoor aggregation room. Although the optics are commercial temperature rated, the modules are located in climate-controlled equipment areas, and the long single-mode runs are entirely within the 80km design target. The DFB transmitter and PIN receiver combination gave stable receive levels over the route, and the 1.25Gbps throughput is exactly right for the existing access layer. We also appreciate that the modules conform to SFP MSA and support DOM, since our NOC can trend optical levels instead of waiting for a service incident. This is the kind of low-drama optic operations teams want.

For a data-center-to-campus extension project, we needed a proven 1390nm CWDM transceiver that would work over existing single-mode fiber and LC patching. The LS-CW391G-80C did exactly that. We installed it as a 1.25Gbps uplink, confirmed the correct 1390nm channel through the passive CWDM infrastructure, and monitored DOM values through our normal network-management workflow. No special configuration was needed beyond selecting the correct compatibility version during procurement. It is a good fit for enterprise backbone, metro Ethernet, and indoor telecom-room applications where a 1G CWDM 80km SFP is required.

Our team needed to reuse a limited pair of single-mode fibers between a central data room and several remote utility sites. We selected multiple CWDM wavelengths and used the 1390nm LS-CW391G-80C for one of the longer 1.25G services. The Duplex LC format integrated directly with our fiber distribution frame, while the SFF-8472 digital diagnostics were available through the switch CLI for normal monitoring. We checked laser TX power, RX power, temperature, and voltage during commissioning, then set alert thresholds based on the measured baseline. The modules have performed consistently and saved us from installing additional outside-plant fiber.
