LINK-PP LS-CW4310-20C anchors mid-range data infrastructure by combining Coarse Wavelength Division Multiplexing with reliable single-mode optics. This commercial-grade transceiver consolidates high-speed throughput, physical media efficiency, and intelligent diagnostics into a compact form factor. It serves as a comprehensive solution for enterprise operators looking to optimize their fiber frameworks.
Built strictly to industry baselines, this transceiver complies with both the SFP+ MSA and SFF-8472 specifications to guarantee multi-vendor interoperability. The hardware is specifically rated for commercial deployments, maintaining stable performance throughout an operating temperature range of 0 to +70°C. This strict adherence to standards prevents deployment anomalies in standard data center racks.
Providing a massive leap from legacy gigabit speeds, the module sustains a continuous 10Gbps line rate to support bandwidth-heavy workloads. This throughput is vital for maintaining low-latency data corridors within core switch fabrics and backbone aggregations. It effectively eliminates data bottlenecks between critical network nodes.
Integrating CWDM capabilities allows the hardware to multiplex multiple optical channels over existing infrastructure, significantly expanding network capacity. This architecture bypasses the financial and physical burden of laying new dark fiber lines. It offers an elegant scaling path by maximizing the utility of every optical strand.
Operating on a fixed 1430nm center wavelength, this device occupies a specific slot within the ITU-T CWDM grid. This precise spectral placement guarantees clean channel isolation, eliminating the risk of overlapping signals or crosstalk. The result is deterministic, noise-free light propagation alongside other active wavelengths.
Designed with a robust link budget, the transceiver carries data over single-mode fiber (SMF) spans up to 20 kilometers. This mid-reach capability is ideal for connecting distributed corporate campuses or bridging regional central offices. It successfully overcomes standard fiber attenuation over extended distances.
The optical interface relies on a standardized duplex LC receptacle, ensuring a small footprint and highly secure patch cable engagement. This compact design supports high-density line card configurations, allowing engineers to maximize port utilization per rack unit. Precision alignment mechanics inside the port keep insertion loss to an absolute minimum.
Onboard Digital Optical Monitoring (DOM) grants immediate visibility into the module's physical layer health. Network management systems can poll real-time diagnostics, including laser bias current, internal temperature, and transceiver power levels. This telemetry allows engineering teams to detect fluctuations and fix potential faults before an outage occurs.

Q: Can this 1430nm SFP module be used on a standard 100GHz or 50GHz DWDM grid splitter? By Q***y on 2026-03-26
A: No, this is a dedicated 20nm spacing CWDM transceiver designed specifically for passive CWDM Mux/Demux infrastructure, not DWDM grids. By admin on 2026-03-27
Q: What happens to the 20km transmission limit if our dark fiber run includes multiple mechanical patch panels and fusion splices? By B***l on 2025-12-28
A: The 20km rating is an estimate based on standard fiber attenuation. You must calculate your total link budget to ensure insertion loss doesn't exceed the module's margin. By admin on 2025-12-29
Q: Is the 1430nm wavelength more susceptible to water-peak attenuation (E-band) on older legacy single-mode fiber? By T***e on 2025-08-04
A: Yes, older G.652A/B fibers may exhibit slightly higher loss at 1430nm compared to 1550nm, so we recommend sweeping your fiber line with an OTDR prior to deployment. By admin on 2025-08-05
Q: What is the typical optical power budget and receiver sensitivity for this 20km reach? By L***l on 2025-03-23
A: The module provides a minimum optical link budget of 10.5dB, featuring a high-sensitivity receiver rated down to -15.5dBm. By admin on 2025-03-24
