The LENOVO 45W2817 SFP (Small Form-factor Pluggable) Transceiver is a high-performance, long-haul, single-mode fiber (SMF) module designed for gigabit Ethernet applications. It is optimized for use in professional networking equipment such as high-speed switches and routers that require a reliable, long-distance fiber optic connection. This transceiver operates over a wavelength of approximately 1310 nm, which is standard for single-mode fiber optic communication, allowing for data transmission over distances of up to 10 kilometers without significant signal loss. The device is also equipped with an optical monitoring (OM) feature, which enables real-time monitoring of the transceiver's operational parameters, including transmitted and received power levels, temperature, and laser bias current. This functionality is crucial for network administrators who need to ensure optimal performance and troubleshoot any potential issues in their fiber optic network. The LENOVO 45W2817 is designed for easy installation and is hot-swappable, meaning it can be connected or disconnected without powering down the network device it is attached to. Its compact size allows for efficient use of space in densely packed networking equipment. Additionally, this transceiver complies with the SFP Multi-Source Agreement (MSA), making it compatible with a wide range of networking devices beyond those manufactured by Lenovo, provided they support the same optical characteristics and form factor.
