    Optical Mux STM-1 155M with 6ethernet and 16E1 is developed based on SDH and EOS technology, which is fully compliant with ITU-T standard. This equipment provides users with two (A and B) STM-1 optical interfaces and at most 6 Ethernets ports. It features VC-12 cross-connect and channel protection. Besides,the SDH mux device can be used as an add-drop multiplexer or aterminal multiplexer to establish chain networks and ring networks of point-to-point and point-to-multipoint.
    PRODUCT CHARACTERISTIC
     Integration of SDH and EOS allows the access of various services.
     Provide up to 6 physically independent 10/100Mbps Ethernet interfaces.
     Multiple clock modes available, including crystal oscillating clock, line-extracted clock and external clock 2MBIT/2MHZ.
     Complete LED alarm indication on front panel.
     Dual SDH optical or electrical interfaces for the set-up of chain network or redundant ring network.
     FC/SFP optical transceivers available, FC by default.
     Network-wide management, simple configuration.
     DC48V and AC220V power supply optional.
