Product Description
The Finisar FWLF-1521-7D-53 SFP transceiver is a high-performance module optimized for long-haul communication links. It enables reliable data transmission at speeds up to 2.67Gb/s, making it suitable for applications requiring extended reach over single-mode fiber infrastructure. This transceiver utilizes a 1550nm wavelength, which is ideal for long-distance transmission due to its low attenuation in optical fibers. The 50km reach capability makes it a cost-effective solution for connecting geographically dispersed network nodes, such as in telecommunications backhaul or metro network deployments. The module is equipped with duplex LC connectors for secure and standard fiber optic connections. It also typically includes Digital Diagnostic Monitoring (DDM) features, providing real-time insights into operational parameters like signal strength and temperature, which are crucial for network management and fault diagnosis.
