Description
The Transition Networks TN-CWDM-SFP-1310-40 is a CWDM SFP transceiver module designed to operate at the 1310nm wavelength, offering an extended transmission distance of up to 40 kilometers. This module is a key component in CWDM (Coarse Wavelength Division Multiplexing) systems, enabling the multiplexing of multiple data streams over a single fiber optic cable by utilizing distinct wavelengths. The 1310nm wavelength is a standard choice within the CWDM spectrum. This SFP transceiver supports data rates up to 1.25 Gbps, making it suitable for Gigabit Ethernet applications. It is intended for use with single-mode fiber (SMF) and features an LC duplex connector for a secure and reliable fiber optic connection. The module complies with the SFP Multi-Source Agreement (MSA), ensuring interoperability with a wide range of networking equipment. Digital Diagnostics Monitoring (DDM) or Digital Optical Monitoring (DOM) capabilities are typically included, providing real-time performance data such as temperature, voltage, transmit optical power, and receive optical power, which is essential for network management and troubleshooting. The TN-CWDM-SFP-1310-40 is an effective solution for expanding network capacity and reach in metropolitan and enterprise environments where longer distances are required. By employing CWDM technology, it allows for the aggregation of multiple communication channels onto a single fiber, significantly increasing bandwidth without the need for deploying additional fiber optic cables. The hot-pluggable nature of the SFP form factor allows for easy installation and replacement without interrupting network operations, making it a practical choice for demanding network environments.
