The small size of the VF-45, about the same as an RJ-45 port, reduces the size
of wiring panels in wiring closets while providing the advantage of “future-proof” fiber
optic technology.
The cable end is a “plug-in” connector, with both fiber strands terminated in
one housing that cannot be improperly inserted. Each port has an Activity (ACT) LED
indicating packets being received, a Link (LK) LED that indicates proper connectivity
with the remote device when lit, and a FDX/HDX LED to indicate full-duplex mode
when lit (or half-duplex when off).

QPM-RJ45 (Twisted Pair), 10/100Mb TP Quad-Port
The QPM-RJ45 module
supports Ethernet twisted pair
segments of any standard length. It is
equipped with a four-port RJ-45
connector, and offers 10/100 full /
half-duplex auto-negotiating
capability on each port. The RJ-45
connector is shielded to minimize
emissions and will allow both
unshielded twisted pair (UTP) and shielded twisted pair (STP) cable connections.
The QPM-RJ45 quad-port module is equipped with a Media Dependent
Interface-Crossover (MDI-X) push-button to allow for one cascaded connection. This
feature eliminates the need for a special twisted pair crossover cable when connecting to
a hub or another switch.
With the push-button in the IN (X) position, the left-most RJ-45 port is used for
cascaded and up-link connections (i.e.: a connection to another hub or switch typically).
When used for segments going to workstations and other user node device connections,
the MDI-X push-button should be in the OUT (=) position.
Each port has an Activity (ACT) LED indicating packets being received, a
Link (LK) LED that indicates proper connectivity with the remote device when lit, a
FDX/HDX LED to indicate full-duplex mode when lit (or half-duplex when off), and a
“speed” LED indicating 100Mb when lit (or 10 Mbps when off).
