About This Part
The Finisar FWDM-1621-7D-57 is a high-performance Small Form-Factor Pluggable (SFP) optical transceiver designed for robust long-haul data transmission. This module, manufactured by Finisar, operates at a data rate of 2.5 Gigabits per second, making it suitable for applications such as Gigabit Ethernet, Fibre Channel, and SONET/SDH networks. Utilizing Coarse Wavelength Division Multiplexing (CWDM) technology, the FWDM-1621-7D-57 specifically transmits at a wavelength of 1570nm, corresponding to CWDM Channel 57. Its advanced optical design enables reliable data communication over distances up to 100 kilometers, facilitating extended reach in metropolitan and access networks. The SFP form factor ensures compatibility with a wide range of networking equipment, providing a standardized and hot-pluggable interface for seamless integration into existing infrastructure. This Finisar SFP transceiver is typically deployed in demanding network environments requiring extended reach and efficient utilization of fiber optic infrastructure. It is critical for telecom operators, internet service providers, and large enterprise data centers that need to connect geographically dispersed sites or extend services over significant distances. The Part Number FWDM-1621-7D-57 module is commonly installed in aggregation switches, core routers, and optical transport platforms that support SFP interfaces, enabling high-bandwidth connectivity between central offices, remote points of presence, and data centers. By leveraging CWDM technology, it helps overcome fiber exhaustion challenges by allowing multiple services to share a single fiber pair, thereby reducing operational costs and deferring the need for new fiber builds. It serves as an essential component for upgrading existing 1G or 10G networks to incorporate 2.5G services over long distances, enhancing network capacity and flexibility.
