Generic CWDM-SFP10G-20S Compatible LINK-PP module is a 10G SFP+ CWDM optical transceiver module designed for efficient 20km data transmission over single-mode fiber. It integrates a DFB laser, a duplex LC interface, and real-time Digital Diagnostic Monitoring within a standard 0°C to 70°C operating range. This module provides a reliable, MSA-compliant hardware setup to optimize fiber capacity in modern network environments.
This transceiver features a hot-pluggable SFP+ footprint for easy installation and maintenance without powering down the system. It is fully compliant with the SFP+ Multi-Source Agreement (MSA) and the SFF-8472 standard. This ensures seamless hardware compatibility and reliable digital diagnostics functions across various networking platforms.
This module delivers a steady line rate of 10Gbps to support demanding data center and enterprise applications. It serves as a reliable solution for upgrading network speeds on local and metropolitan fiber loops. The fast data rate helps reduce latency and ensures smooth traffic flow across core switching paths.
By utilizing Coarse Wavelength Division Multiplexing (CWDM), this transceiver allows multiple data channels to share a single fiber strand. This technology maximizes existing infrastructure capacity and prevents the high costs of laying new cables. It is an ideal choice for expanding network bandwidth efficiently.
Operating at a specific 1450nm center wavelength, this module uses a CWDM DFB laser to maintain stable optical output. This precise wavelength assignment prevents signal interference with neighboring channels in a CWDM multiplexing system. It guarantees clean signal integrity for complex multi-channel configurations.
Equipped with a high-sensitivity PIN photodiode, the transceiver reliably covers distances up to 20km on standard single-mode fiber. It provides an optimal link budget for campus networks, metropolitan spans, and point-to-point connections. The extended reach ensures stable communication across intermediate optical infrastructure.
The module is built with an industry-standard duplex LC connector interface for secure optical fiber patching. This physical design ensures low optical insertion loss and highly reliable port connectivity. It allows quick integration into existing patch panels and enterprise switches.
Featuring built-in Digital Diagnostic Monitoring (DDM), this transceiver tracks key operational telemetry in real time. Network administrators can easily monitor critical metrics such as optical power, voltage, and module temperature. This proactive monitoring assists in fast troubleshooting and prevents sudden network downtime.

Q: Does this specific 1450nm wavelength suffer from high attenuation when passing through old, dirty fiber patch panels? By H***e on 2026-02-02
A: The 1450nm wavelength is highly resilient, but dirty bulkheads cause insertion loss; we always advise cleaning the duplex LC tips with a click-cleaner before mating. By admin on 2026-02-03
Q: Can we run this 1450nm wavelength over a single strand of fiber using a BiDi setup instead? By C***y on 2025-10-17
A: No, this is a duplex LC module that requires a dedicated pair of fibers — one strand for transmitting (TX) and one strand for receiving (RX). By admin on 2025-10-18
Q: What happens to the link if there is a severe mismatch on the CWDM Mux channel wavelength? By P***h on 2025-06-06
A: The link will not establish because the passive Mux will filter out the 1450nm signal if it is connected to a different channel port; ensure both ends match the 1450nm grid. By admin on 2025-06-07
