A MiniGBIC module designed to divide or terminate an optical network cable at a distance of up to 10km and with a maximum speed of 1.25Gbit/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, where it is inserted into the SFP slot, or from the MC220L media converter. On the other side of the connection, the TL-SM321A module must be used. The module uses WDM technology to enable bidirectional communication over a single fiber.
