airlive 1000Base-SX MiniGBIC transceiver 500M, Hot pluggable SFP-SX-1

.25G-500M

Overview

The AirLive SFP-SX-1.25G-500M is a low power, high performance and cost- effective multi mode SFP Fiber transceiver for serial optical data communication applications up to 1.25Gbps and 500M. The low jitter and high sensitivity module is intended for single mode dual fiber and operates at a nominal wavelength of 850nm, the operating temperature 0°C~70°C and the module is hot pluggable.
The transceiver incorporates TX Disable control, TX-Fault, and RX_LOS monitor functions. It is a duplex LC connector transceiver designed for use in Gigabit Ethernet applications and to provide IEEE802.3z compliant link and Class I Laser safety compliant link.

The suitable applications are such as High-speed storage area networks, computer cluster cross-connect, customized high-speed data pipes, and more.
