2.1.2. Cabling Requirements
To help ensure a successful installation and keep network performance at optimum levels, take
care to use Cat.5e grade or higher cabling. Ensure that stranded core UTP cable, if used, runs
for no more than 10 metres, and that solid core runs for a maximum of 100 metres. Poor cabling
is the most common cause for network dropouts or poor performance.
2.1.2.1. Cabling Requirements for UTP Ports
•
For Ethernet copper network connections, the UTP cable used must be Cat. 3 grade as a
minimum, with a maximum length of 100 metres
•
For Fast Ethernet copper network connections, the UTP cable used must be Cat. 5 grade as a
minimum, with a maximum length of 100 metres
•
For Gigabit Ethernet copper network connection, UTP cable used must be Cat.5 grade or
higher, with a maximum length of 100 metres. Cat.5e grade UTP cable is recommended.
2.1.2.2. Cabling Requirements for 100Base-FX Modules
There are two categories of fibre optic modules - multimode (MM) and single-mode (SM). The
later come in different models depending on the distance required. Modules for the MS888G2
come with a variety of fibre interfaces including SC, ST, MT-RJ and WDM SC.
The following table lists the types of fibre optic cable that are supported by modules installed in
the Alloy MS888G2. Other cable types not listed here may be supported; please contact the
supplier of your switch for details.

2.1.2.3. Cabling Requirements for 1000SX/LX/ZX SFP Modules
There are two categories of fibre optic modules - multimode (MM) and single-mode (SM). The
later is categorised into several classes by the distance it supports. These are SX, LX, LHX, ZX
and EZX. The majority of mini-GBIC modules available use a LC type connector. The connector
types used currently on Alloy mini-GBIC modules are LC and WDM SC, for the following module
types:
•
Gigabit Fibre with multimode LC SFP mini-GBIC modules
•
Gigabit Fibre with single-mode LC mini-GBIC modules
•
Gigabit Fibre with single-mode/single core WDM SC 1310nm SFP mini-GBIC modules
•
Gigabit Fibre with single-mode/single core WDM SC 1550nm SFP mini-GBIC modules
The following table lists the types of fibre optic cable that are supported by SFP mini-GBIC
modules installed in the Alloy MS888G2. Other cable types not listed here may be supported;
please contact the supplier of your switch for details.
