1. Introduction
1.1. Overview of the 8 Port Gigabit Web Managed Switch
The Alloy 8 Port Gigabit Switch meets all IEEE 802.3/u/x/z Gigabit and Fast Ethernet
specifications. The 8 Port Gigabit Switch features 8x 10/100/1000Mbps copper RJ-45 ports
and 2x paired Gigabit Ethernet SFP Ports. The SFP ports can be used to install a range of
optional mini-GBIC Gigabit Ethernet Port Modules (which provide the ability to connect
multimode and/or singlemode fibre optic cable links – see below); the SFP ports are each
paired with one of the 10/100/1000Mbps copper RJ-45 ports. The switch is managed
through any of the Ethernet RJ-45 ports, using a web-based browser such as Internet
Explorer.
The SFP ports can support the following optional mini-GBIC modules for fibre optic cable
connections (either singlemode or multimode terminated in LC type connectors):
• 1000Mbps multimode 1000Base-SX, 850nm, max. range 500m
• 1000Mbps singlemode 1000Base-LX, 1310nm, max. range 10Km
• 1000Mbps singlemode 1000Base-LHX, 1310nm, max. range 40Km
• 1000Mbps singlemode 1000Base-LHX, 1550nm, max. range 40Km
• 1000Mbps singlemode 1000Base-ZX, 1550nm, max. range 70Km
• 1000Mbps singlemode 1000Base-EZX, 1550nm, max. range 100Km
• 1000Mbps WDM singlemode/singlecore 1310nm, max. range 20Km
• 1000Mbps WDM singlemode/singlecore 1550nm, max. range 20Km
Notes: * The two WDM (Wave Division Multiplexer) mini-GBIC modules are
designed to facilitate a link over a single core of singlemode fibre cable.
The two units must be used in a paired manner, one at either end of the link.
* Mini-GBIC modules that are designed to the relevant standards should be
compatible with any make of switch with SPF ports. If you have concerns
regarding compatibility, please contact the supplier of your mini-GBIC
product.
The 10/100/1000Mbps copper ports meet all IEEE 802.3/u/x/z Gigabit and Fast Ethernet
specifications.
The 1000Mbps SFP Fibre ports via optional mini-GBIC modules are compliant with all IEEE
802.3z and 1000Base-SX/LX/LHX/ZX/EZX standards.
1000Mbps single fibre WDM transceivers are designed with an optic Wavelength Division
Multiplexing (WDM) technology that transports bi-directional full duplex signals over a single
fibre core.
