About This Part
The Finisar FWDM-1621-7D-47 is a high-performance Small Form-Factor Pluggable (SFP) transceiver engineered for robust optical data communication. As part of the Finisar family of optical modules, this unit is specifically designed for Coarse Wavelength Division Multiplexing (CWDM) applications, enabling efficient utilization of existing fiber infrastructure. Operating at a nominal wavelength of 1470nm, corresponding to CWDM Channel 47, it supports a data rate of 2.5 Gbps. This makes the Part Number FWDM-1621-7D-47 suitable for various protocols including OC-48/STM-16 SONET/SDH, 2.5G Fibre Channel, and Gigabit Ethernet applications. Its key technical specification highlights an impressive optical link budget, allowing for reliable data transmission over distances up to 100 kilometers, making it ideal for metropolitan and regional network deployments. The SFP form factor ensures hot-pluggability and compatibility with a wide range of network equipment, providing flexibility and ease of integration into diverse networking environments. This Finisar SFP CWDM transceiver is typically deployed in core, metro, and access networks where extending optical reach and increasing fiber capacity are critical. It is commonly installed in switches, routers, and optical transport platforms from leading network equipment vendors, supporting multi-service provisioning platforms (MSPPs) and wavelength multiplexing systems. Telecommunication operators, Internet Service Providers (ISPs), and large enterprise data centers leverage the FWDM-1621-7D-47 to consolidate multiple data streams onto a single fiber pair, thereby reducing the need for costly new fiber installations. It effectively solves the challenge of long-distance connectivity in scenarios where direct fiber runs are impractical or cost-prohibitive, offering a cost-efficient alternative to deploying additional dark fiber. This module serves as a vital component for upgrading existing infrastructure to support higher bandwidth demands over extended distances without a complete network overhaul.
