Product Description
The Infinera TOM-MR-D55-LR2 is an optical transceiver module designed for extended-distance communication over single-mode fiber (SMF). The 'MR' in the part number often denotes Medium Reach or Metro Reach, and the 'D55' strongly suggests an operating wavelength of 1550nm, which is commonly used for longer-distance transmissions compared to 1310nm. The 'LR2' designation indicates a specific Long Reach specification, typically supporting distances ranging from 40km up to 80km, depending on the fiber type and network conditions. This transceiver operates at a standard SFP form factor, ensuring compatibility with a wide range of networking equipment that supports SFP modules, such as switches, routers, and optical transport systems. It features a duplex LC connector for secure fiber optic cable termination. The 1550nm wavelength is chosen for its lower attenuation in single-mode fiber over long distances, making it ideal for backbone networks, metropolitan area networks (MANs), and inter-building connectivity where significant distances need to be covered. As a product from Infinera, a leader in optical networking, this transceiver is built for high reliability and performance. It plays a crucial role in extending network reach and capacity, enabling service providers and large enterprises to deliver high-bandwidth services efficiently. The specific wavelength and reach capabilities make it a valuable component for advanced optical network designs.
