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 1000SX/LX/ZX SFP Modules
There are two categories of fibre optic cable ‐ 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 Alloy POEGEM24T4SFP. Other cable types not listed here may be supported; please
contact the supplier of your switch for details.
