Magnum Quad-Series Fiber Switches 

Installation and User Guide (06/03) 

Connecting Fiber Optic SC-type, "Snap-In" 

 

The following procedure applies to installations using a QPM with SC-type 

fiber connectors, i.e., using QPM-MSC, QPM-SSC single-mode, and QPM10-MSC. 

 

When connecting fiber media to SC connectors, simply snap on the two square 

male connectors into the SC female jacks of the QPM until it clicks and secures. 

 

When using single-mode fiber cable, be sure to use single-mode fiber port 

connectors.  Single-mode fiber cable has a smaller diameter than multi-mode fiber cable 

(9/125 microns for single-mode, 50/125 or 62.5/125 microns for multi-mode where xx/xx 

are the diameters of the core and the core plus the cladding respectively). Single-mode 

fiber allows full bandwidth at longer distances, and may be used to connect 10 Mb nodes 

up to 10 Km apart, or 18Km with the QPM-SSC. 

The same procedures as for multi-mode fiber applies to single-mode fiber 

connectors.  Follow the steps listed in Section 3.2.2 above. 

Connecting Twisted Pair (RJ-45,CAT3, CAT5, Unshielded or  
Shielded) 

The RJ-45 ports of the Magnum Quad-Series can be connected to the following 

two media types: 100BASE-TX and 10BASE-T.  CAT 5 cables should be used when 

making 100BASE-TX connections. When the ports are used as 10BASE-T ports, CAT 3 

may be used.  In either case, the maximum distance for unshielded twisted pair cabling is 

100 meters (328 ft). 

IEEE Standard          Connector  

Twisted Pair (CAT 3, 4, 5)                  10BASE-T                  RJ-45 

          

Twisted Pair (CAT 5)  

 100BASE-TX                RJ-45            

 

NOTE :   It is recommended that high quality CAT. 5 cables (which work for both 10 Mb 

and 100Mb) be used whenever possible in order to provide flexibility in a 
mixed-speed network, since dual-speed ports are auto-sensing for either 10 and 
100Mb/s.  

  The following procedure describes how to connect a 10BASE-T or 100BASE-

TX twisted pair segment to the RJ-45 port. The procedure is the same for both 

unshielded and shielded twisted pair cables. 

1.    Using standard twisted pair media, insert either end of the cable with an RJ-45 

plug into the RJ-45 connector of the port. Note that, even though the connector is 

shielded, either unshielded or shielded cables and wiring may be used.  

2.   Connect the other end of the cable to the corresponding device
