About This Part
The Finisar FWDM-1621-7D-49 is a high-performance Small Form-Factor Pluggable (SFP) transceiver module engineered for robust optical data transmission within enterprise and telecommunications networks. This specific module belongs to Finisar's extensive line of optical transceivers, renowned for their reliability and adherence to industry standards. Operating at a data rate of 2.5 Gigabits per second (Gbps), the FWDM-1621-7D-49 leverages Coarse Wavelength Division Multiplexing (CWDM) technology, specifically utilizing the 1490nm wavelength, identified as CWDM Channel 49. Its primary function is to facilitate long-haul optical links, capable of extending network reach up to 100 kilometers over single-mode fiber. The SFP form factor ensures compatibility with a wide array of networking equipment, providing a hot-pluggable interface for seamless integration. Designed for duplex communication, it typically employs LC connectors for fiber optic termination, making it a versatile component for various high-speed optical infrastructure deployments. This Finisar SFP transceiver is typically deployed in core and aggregation layers of telecommunications networks, metropolitan area networks (MANs), and regional long-haul links where extended reach and efficient wavelength utilization are critical. It finds application in various network platforms, including Ethernet switches, routers, and dedicated optical transport equipment that support SFP interfaces. Telecom operators, Internet Service Providers (ISPs), and large enterprise data centers utilize the FWDM-1621-7D-49 to establish reliable, high-speed connections between geographically dispersed sites or within campus environments requiring significant distances. The CWDM technology allows multiple data streams to be transmitted simultaneously over a single fiber pair using different wavelengths, thereby maximizing fiber capacity and reducing the need for costly new fiber deployments. This module is instrumental in solving challenges related to long-distance data transmission without signal degradation, offering a robust solution for expanding network infrastructure or upgrading existing 2.5G optical links to achieve greater reach and efficiency.
