 MPX449 Digital
Distribution Frames
MPX449 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:
Aluminum frame, Coaxial connector sub panel is made up os stainless
steel,fine looking and antiseptic.
Flexible allocation and easy to install.
Gold plated surface of the coaxial, connector,low contact resistance,fine
connection, it is very convenient to distribute.
Coaxial connector adoptor adopts new push/pull lock, easy to remove.
One cable one hole, cables are in good order and pleasin, easy to
maintain.
Billboard structure assembled by base frame and extended frames, flexible
and easy to assemble, high capacity, materials and space.
Can take the place of AT&T.
