1.Introduction
1.1.Overview of GSM Series SNMP Managed Switches
The GSM Series Switches are high performance web and SNMP managed switches that provide a mix of mini-GBIC/SFP ports and 10/100/1000Mbps copper Ethernet ports. With optional fibre transceivers installable into the mini-GBIC slots, a combination of either multi-mode fibre transceivers for short distance applications or single-mode fibre transceivers for long distance applications can be used to construct a high-speed fibre backbone.
Intelligent Network features, offer a complete management solution that can enable you to scale your network from a single departmental switch right up to any Enterprise environment. STP and RSTP offer network redundancy features, IGMP snooping offers support for Streaming Video and Multicasting images, Tagged VLAN offers logical security and management of nodes within defined groups. QOS based on port priority queues and TOS bytes ensure efficient forwarding of critical network data.
All Ports support non-blocking maximum wire speed performance with Auto-negotiation and Auto-MDIX functions for simplified deployment.
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 100Km
•1000Mbps WDM single-mode/single-core 1310nm, max. range 20Km
•1000Mbps WDM single-mode/single-core 1550nm, max. range 20Km
------This is not an exhaustive list of SFP modules available--------
Notes: * The two WDM (Wave Division Multiplexing) 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 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.
