Description
The Finisar FTRJ-8519-7D2EM is a Small Form-factor Pluggable (SFP) transceiver module designed for Fibre Channel applications, operating at a data rate of 2.125Gb/s. It is intended for use with multi-mode fiber (MMF) and provides a transmission distance of up to 550 meters. This makes it suitable for short-reach connections within data centers, storage area networks (SANs), and enterprise environments. The transceiver utilizes an 850nm wavelength, which is standard for short-wavelength, high-speed communication over MMF. The LC duplex connector ensures a secure and reliable connection for the fiber optic cable, facilitating easy installation and maintenance. The SFP form factor allows for hot-swappable deployment in compatible networking equipment. This Finisar SFP module is an ideal choice for Fibre Channel switches, host bus adapters (HBAs), and other SAN infrastructure components that require high-speed, reliable connectivity over short to medium distances within a facility. Its performance is optimized for MMF, providing cost-effective high-bandwidth solutions for local area networking.
