3.2.0.5 Connecting Twisted Pair (CAT5e or better, Unshielded or Shielded)

The RJ-45 Gigabit ports of the Multilink ML1200 can be connected to the media types, 1000BASE-T or CAT 5E or better 100-ohm UTP or shielded twisted pair (STP) balanced cable. The CAT 5E or better 100-ohm UTP or shielded twisted pair (STP) balanced cable is recommended to use when making 1000BASE-TX connections. In either case, the max distance for unshielded twisted pair cabling is 100 meters (328 ft).

Media	IEEE Standard	Connector
Twisted Pair (CAT 5e)	1000BASE-T	RJ-45

The following procedure describes how to connect a 1000BASE-T twisted pair segment to the RJ-45 port. The procedure is the same for both unshielded and shielded twisted pair cables.

1.1000BASE-T connections require that all four pairs or wires be connected. 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

3.Use the LINK LED to ensure proper connectivity by noting that the LED will be illuminated when the unit is powered and proper connection is established

3.2.0.6Gigabit SFP (Small Form-factor Pluggable) Optical Transceivers

The small form-factor pluggable (SFP) is a compact optical transceiver used in optical communications for both telecommunication and data communications applications. Due to its compact, hot pluggable characteristics, SFPs are becoming a very popular choice for various applications. The small-chassis Multilink ML1200 is designed for industry-standard Gb-SFPs and Gb-SFPCU (copper) for user selection of the SFP gigabit media type as desired.

All SFPs used in Multilink ML1200s are compliant with the industry standard Multi-Source

Agreement (MSA) ensuring compatibility with a wide range of networking kit.

It is highly recommended to remove the fiber cable first before removing the SFP transceiver for any reason. Not removing the fiber cable first can damage the fiber cable, cable connector or optical interfaces. It is advised not to remove and insert a SFP transceiver frequently as this may shorten its useful life.

Always use an ESD wrist strap while handling the SFP transceivers since the SFP modules are static sensitive devices.

The copper 1000BASE-T SFP transceiver port supports 1000Mb only. It is recommended to use a straight-through RJ-45(4-twisted pair) connection while connecting to any Server/ workstation. While connecting with any Switch/repeater or other device, it is recommended to use Crossover RJ-45 (4-twisted pair) category 5 or higher cabling. The maximum length supported on copper 1000BASE-T is 100mts (328 ft.).
