CHAPTER 3: INSTALLATION CONNECTING ETHERNET MEDIA
MULTILINK ML1600 ETHERNET COMMUNICATIONS SWITCH – INSTRUCTION MANUAL 3–3
When connecting fiber media to SC connectors, simply snap on the two square male
connectors into the SC female jacks of the module until it clicks and secures.
3.2.4 Connecting Single-mode Fiber Optics
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 versus 50/125 or 62.5/125 microns for multi-mode, where xx/xx
represent the core diameters and the core plus cladding, respectively). Single-mode fiber
allows full bandwidth at longer distances and may be used to connect 10 Mb nodes up to
10 km.
The same connection procedures for multi-mode fiber apply to single-mode fiber
connectors. Follow the steps listed Connecting ST-type Fiber Optics (twist-lock) on page 3–2.
3.2.5 Connecting RJ45 Twisted Pair
The RJ45 ports of the ML1600 can be connected to the following two media types:
100Base-TX and 10Base-T. CAT Five 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 m (328 ft.).
Note
It is recommended that high quality CAT. 5 cables (which work with 10 Mb and 100 Mb) be
used whenever possible to provide flexibility in a mixed-speed network, as dual-speed
ports are auto-sensing for 10 and 100 Mb/s.
The following procedure describes how to connect a 10Base-T or 100Base-TX twisted pair
segment to the RJ45 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 RJ45
plug into the RJ45 connector of the port. Even though the connector is
shielded, either unshielded or shielded cables may be used.
2. Connect the other end of the cable to the corresponding device.
3. Use the LINK LED to ensure connectivity by noting that the LED will be
illuminated when the unit is powered and connection is established.
The ML1600 RJ45 Gigabit ports can be connected to 1000Base-T, CAT.5E (or better), 100 Ω
UTP, or shielded twisted-pair (STP) balanced cable media. The CAT.5E or shielded twisted
pair (STP) balanced cable is recommended when making 1000Base-TX connections. In
either case, the maximum distance for unshielded twisted pair cabling is 100 m (328 ft.).
Note
It is recommended that high quality CAT. 5E cables (which work at both 100 and 1000 Mb)
be used whenever possible to provide flexibility in a mixed-speed network.
The following procedure describes how to connect a 1000Base-T twisted pair segment to
the RJ45 port. The procedure is the same for both unshielded and shielded twisted pair
cables.
