AMP Netconnect MRJ21 Connector
System for Data Centers

MRJ21-MRJ21

MRJ21-RJ45 Hydra |
The MRJ 21 Connector System
Solution is a high-density, high-performance, modular copper
cabling system. AMP Netconnect's matched powersum 24-pair
cabling and connector solution provides a variety of
applications to up to 12 ports with a single cable. This
solution supports any plug and play environment including
data centers and zone cabled or open office environments.
When utilizing AMP Netconnect's PC board mounted solution,
the MRJ 21 enables much higher port density than the common
Modular plug/jack interface, which can significantly reduce
active port costs.

Product Features: |
|
|
-
|
MRJ 21 provides an
application independent copper platform for
applications today and into the future -
including Gigabit, VoIP & powered Ethernet. |
|
-
|
The small size of the MRJ
21 connector and cabling reduces cable bulk
in pathways and spaces, enabling much higher
port counts in a smaller space. |
|
-
|
Factory termination and
testing of the cassettes and patch panels
provide assurance of pluggable performance
on site. This enables rapid installation or
MACs with pre-tested quality. |
|
-
|
The modularity of this
solution significantly reduces time to
install or migrate from a 10/100BASE-T
2-pair platform to a Gigabit Ethernet 4-pair
platform. Upgrading is as simple as
unplugging one cassette and plugging in the
new one. The same cable is re-usable. |
|
-
|
Cassettes and patch
panels break out high performance 24-pair
solutions to the appropriate wiring patterns
for standards based 10/100BASE-T, Gigabit
Ethernet, and other applications. |
|
- |
Common cable assembly
lengths provide readily available, pluggable
solutions, speeding implementation. |
