 MPX448 Digital
Distribution Frames
MPX448 Digital Distribution Frames is used for distribution and communication
of difital terminal equipment or sequence control exchanger whose
transmit rate between 2-155Mb/s. It can use and maintain, flexible
to meet the needs of changes of business.
Features:
The frame structure is open, easy to operate and maintain.
Flexible allocation and easy to install.
Gold plated surface of the coaxial,connector,low contact resistance,fine
connection, it is very convenient to distribute. The spliting unit
can turn over down 90·ã, make it easy to operate and maintain.
Spacious room for wire-running, cables ate in good order and pleasing.
Can take the place of SIEMENS.
