LINK-PP LS-CW4710-20C is a CWDM optical transceiver working at 1470nm, designed for up to 20km transmission over single-mode fiber with a duplex LC interface. It combines CWDM wavelength capability with stable optical components and integrated diagnostics to support consistent 10Gbps data links. The module is built for efficient fiber usage, clear monitoring, and easy integration into existing network systems.
This module adopts a hot-pluggable SFP+ footprint, allowing insertion or removal without interrupting system operation. It follows SFP+ MSA and SFF-8472 standards, ensuring broad compatibility with switches and routers. The compact structure fits well in high-density networking environments.
Supporting 10Gbps data transmission, it enables stable communication across backbone and aggregation layers. It is suitable for campus networks and enterprise infrastructures that require steady bandwidth. The module helps maintain reliable data exchange between key network nodes.
CWDM functionality allows multiple signals at different wavelengths to share one fiber. This reduces fiber consumption and helps lower deployment costs. It also makes network expansion more flexible without major infrastructure changes.
Operating at 1470nm, it aligns with standard CWDM channel spacing for multi-wavelength transmission. This wavelength supports stable signal propagation over single-mode fiber. It also helps reduce interference between channels.
The module supports link distances up to 20km on SMF, making it suitable for medium-range connections. It can be used to connect buildings or network segments across extended areas. Signal stability is maintained within the specified distance.
Equipped with a duplex LC connector, it provides separate paths for transmitting and receiving signals. This interface is widely used and easy to deploy with standard fiber cables. It ensures stable and secure optical connections.
Built-in DDM enables real-time tracking of parameters such as temperature, voltage, bias current, and optical power. This allows users to monitor module status during operation. It supports better maintenance and faster troubleshooting.

Q: Do we need multi-mode fiber or single-mode fiber patch cords for our CWDM MUX panel connection? By S***y on 2026-03-25
A: Single-mode fiber is mandatory for this link. Multi-mode fiber causes severe optical dispersion and attenuation at 1470nm, whereas duplex LC single-mode patch cords ensure optimal signal transmission and full 20km optical reach. By admin on 2026-03-26
Q: Can we monitor internal transceiver temperature in real time inside densely populated switch faceplates? By I***h on 2025-08-24
A: Yes. This transceiver features a Digital Diagnostic Monitoring (DDM) function that reports live operating temperature to the host device. You can access these metrics via standard switch CLI diagnostic tools or poll them remotely using SNMP. By admin on 2025-08-25
Q: Can I drop this 1470nm SFP+ module into our current CWDM filter tray alongside other wavelengths on one fiber pair? By N***r on 2025-04-04
A: Yes, it’s built for standard CWDM grid integration. Just patch it into your 1470nm MUX/DEMUX port, and it will run clean, multi-channel traffic over the same single-mode line with solid spectral stability. By admin on 2025-04-05
