0231A2-1530 is a commercial-grade 1G SFP 1530nm CWDM optical transceiver module designed to deliver reliable data links over single-mode fiber up to 20 km. Featuring a duplex LC interface and real-time digital monitoring, this unit provides a dependable physical-layer solution for bandwidth expansion in modern network infrastructures.
This transceiver utilizes a standard hot-pluggable SFP footprint that allows seamless installation without shutting down host systems. It strictly complies with the multi-source agreement (MSA) specification to ensure cross-platform hardware compatibility.
Line-rate data transmission speeds up to 1.25Gbps enable efficient traffic handling across enterprise backbones and metro access links. By maximizing data throughput over existing lines, the module helps operators relieve congestion in fiber-limited environments.
Coarse Wavelength Division Multiplexing (CWDM) allows multiple data channels to combine over a single fiber pair. This capability significantly increases total bandwidth capacity while reducing the need to lay new optical cables.
The dedicated 1530nm central optical channel ensures accurate signal routing within multi-channel CWDM grid configurations. The precise spectral grid placement minimizes crosstalk and maintains stable channel separation across the fiber link.
An integrated CWDM DFB laser and PIN photodetector enable steady signal delivery across single-mode fiber links up to 20 km. This coverage distance makes it suitable for connecting distributed network switches across campus and regional sites.
Industry-standard duplex LC connectors deliver low insertion loss and consistent physical alignment with optical patch cords. The compact latching mechanism ensures secure cable engagement in high-density switch configurations.
Built-in digital optical monitoring capability complies with SFF-8472 standards to track key operational parameters like optical power and temperature. Network administrators can access these telemetry diagnostics directly from the host equipment interface.
0231A2-1530 meets international quality and environmental standards, holding ISO 9001, CE, RoHS, and FCC certifications. These compliance certifications verify that the module satisfies strict requirements for operational safety, manufacturing quality, and electromagnetic compatibility.
Each module undergoes 100% line-rate testing, optical spectrum inspection, and thermal cycling before shipment. These factory testing procedures verify physical layer signal integrity and stable optical power levels.
Compliance documentation confirms that materials and electrical components meet global safety and environmental guidelines. These verified standards ensure low electromagnetic interference and lead-free hazardous substance control.
The module firmware is validated on major networking switches and routers to ensure seamless port recognition. Proper EEPROM coding guarantees immediate link setup and full digital diagnostic monitoring support in host devices.

Q: If we need to swap or inspect this 1530nm CWDM module during maintenance, do we have to shut down the switch port or reboot the chassis first? By O***n on 2026-04-27
A: No. The LS-CW531G-20C CWDM SFP features a fully compliant hot-pluggable SFP footprint. You can safely insert or remove the transceiver from an active switch port without disrupting adjacent ports or powering down the system. By admin on 2026-04-28
Q: We have an existing passive 8-channel CWDM Mux/Demux box. Can we patch this 1530nm module directly into the 1530nm line port using our standard OS2 single-mode duplex LC patch cables? By M***d on 2026-01-19
A: Yes, exactly. The LS-CW531G-20C module is built with a standard Duplex LC receptacle and operates at a precise 1530nm CWDM DFB wavelength over single-mode fiber. It is fully compatible with standard passive CWDM multiplexers matching the 1530nm ITU grid channel. By admin on 2026-01-20
A: No. The high-performance DFB laser inside the LS-CW531G-20C is thermally stabilized to stay tightly centered within the standardized CWDM 1530nm channel grid (1530nm ±6.5nm) across its entire 0°C to +70°C operating envelope. Even under sustained high thermal loads near +70°C, the spectral output will not drift into neighboring 1510nm or 1550nm channels. By admin on 2025-08-14
Q: We have an older SAN storage setup. Does this module support 1.063Gbps Fibre Channel traffic alongside standard Ethernet? By T***r on 2025-02-16
A: Yes. The module supports data rates up to 1.25Gbps and natively handles legacy 1.063Gbps Fibre Channel, making it suitable for both SAN storage links and IP data networks. By admin on 2025-02-17
