1. Introduction
1.1 Overview
Alloy 16/24 Port Gigabit Switches meet all IEEE 802.3/u/x/z standards Gigabit and Fast Ethernet specifications. The 16 Port Gigabit Switch model features 16x 10/100/1000Mbps copper RJ-45 ports and 4x 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 single mode fibre optic cable links – see below); the SFP ports are each paired with one of the 10/100/1000Mbps copper RJ-45 ports. The 24 Port Gigabit Switch is identical other than featuring 24x 10/100/1000Mbps copper RJ-45 ports. Both switches are managed through any of their 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 single mode or multimode terminated in LC type connectors):
•1000Mbps multimode 1000Base-SX, 850nm, max. range 500m
•1000Mbps single mode 1000Base-LX, 1310nm, max. range 10Km
•1000Mbps single mode 1000Base-LHX, 1310nm, max. range 40Km
•1000Mbps single mode 1000Base-LHX, 1550nm, max. range 40Km
•1000Mbps single mode 1000Base-ZX, 1550nm, max. range 70Km
•1000Mbps single mode 1000Base-EZX, 1550nm, max. range 120Km
•1000Mbps WDM single mode/single core 1310nm, max. range 20Km
•1000Mbps WDM single mode/single core 1550nm, max. range 20Km
•1000Mbps WDM single mode/single core 1310nm, max. range 40Km
•1000Mbps WDM single mode/single core 1550nm, max. range 40Km
•1000Mbps CWDM single mode/single core 1470 - 1610nm, max. range 70Km
Notes: * The two WDM (Wave Division Multiplexer) mini-GBIC modules are designed to facilitate a link over a single core of single mode 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 SFP 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.
