Description
Overview
GAOTek optical multiplexer is for transmitting other data such as RS232 or RS485 or RS422, two optical interfaces for optional 1+1 auto protection switch (APS).4 slots of tributary with variant plug-in modules which included 4xE1 channels module, 4 or 8 or 16 x FXO or FXS module and 2 x Nx64K V.35 module. The maximum capacity will be up to 4 plug-in modules which could be in combination with the above modules. The high flexibility, performance, is the best solution for voice or data or video services in existed market.
