Description
The Transition Networks TN-SFP-OC3SB21 is a Small Form-factor Pluggable (SFP) transceiver module designed for OC-3 (155 Mbps) network applications. This module operates at a 1310nm wavelength and is intended for use with single-mode fiber optic cables, enabling longer transmission distances compared to multimode fiber. It is engineered to support data links up to approximately 21 kilometers, making it suitable for extending network connectivity in metropolitan area networks and other long-reach scenarios. Featuring an LC connector, the TN-SFP-OC3SB21 ensures a secure and stable physical connection, which is vital for maintaining signal integrity over its specified transmission range. The 1310nm wavelength is a common choice for single-mode fiber applications requiring moderate to long distances. The module includes Digital Diagnostic Monitoring (DDM) capabilities, allowing network administrators to monitor key operational parameters such as optical transmit and receive power, temperature, and voltage. This feature is crucial for effective network management and troubleshooting. Designed for ease of deployment and minimal network disruption, the TN-SFP-OC3SB21 is hot-pluggable, meaning it can be installed or replaced without powering down the host equipment. It complies with industry standards, including SFF-8472, ensuring compatibility with a wide range of networking devices. This transceiver provides a reliable solution for extending network infrastructure over significant distances.
