MiniGBIC module designed to divide or terminate an optical network route at a distance of up to 10 km at a maximum speed of 1.25 Gbit / s (1000Base-BX). MiniGBIC modules can be set up according to current network speed requirements. Also, when changing the configuration, it is not necessary to change the entire active element - just replace the individual module. The module is powered directly from the switch to the SFP slot or the MC220L media converter. On the other side, the TL-SM321A module must be used. The module uses WDM technology to enable bidirectional communication with only one fiber.
