WIRELESS BROADBAND SWITCHES VOIP NAS TigerSwitch 10G SMC8708L2

The TigerSwitch 10G - SMC8708L2 is a manageable Layer-2 Switch with eight 10G XFP slots and a high-performance 160Gbps non-blocking architecture which guarantees si- multaneous full duplex activity on all ports, even when running at full load.

TigerStack ll 1000 SMC8824M/ SMC8848M

The TigerStack II 10/100/1000 1000 SMC8824M/48M stacks up to 8 units in a stack, pro- viding up to 384 Gigabit ports. A stack can be created with either of the 24 or 48 port switches, providing unprecedented fl exibility. It provides up to 48 built-in copper Gigabit ports, including (4) Combo SFP ports supporting either copper links or SFP adapters for easy, fl exible connection to fi ber-based Gigabit media and a switching capacity of up to 176Gbps. The 2 10G module slots on the rear of the switch provide support for 10G con- nections. These provide high connections to the core of a network and are in additon to the 2 stacking connectors giving high capacity connections to the other units in the stack.

TigerSwitch 10G SMC8724-10BT

The TigerSwitch 10G SMC8724-10BT is a 24 port 10G Switch. It is the fi rst high density 10GBASE-T switch including 20 x 10GBASE-T ports complying with IEEE802.3an support- ing up to 100m on Cat6a cabling. For connecting buildings or more remote locations 4 x XFP ports are included for longer distances. This switch is ideal of datacenter and cluster ap- plications enabling wirespeed performance using easy to manage cabling. The manage- ment software included is L2/L4 for advanced control and quality of service.

10G Network Interface Cards SMC10GPCIe-10BT/SMC10GPCIe-XFP

The SMC Tiger Card™ 10G portfolio includes 10GBASE-T and XFP. They are PCIe (x8) half height cards supporting wirespeed connections from your servers to the rest of the network. These single port server adapters bring high performance and a range of distances giving customers fl exibility. The extremely low power consumption, low latency and high throughput of the SMC Ti- ger Card™ 10G server adapter family makes it the best solution for the networking environments such as high performance computing (HPC), database clusters, and video on demand.

XFP 10G SMC10GXFP-LR/SMC10GXFP-SR

SMC’s XFP 10G can be used with any of SMC’s XFP based 10G solutions. Choose from XFP transceivers for short range (10GBASE-SR, 300m) to long range (10GBASE- ER, 40 km)

Uplink Modules SMCXFPMOD

1 port uplink modules for the SMC8824M and SMC8848M providing 10G connections for Fiber and 10GBASE-T. NOTE: When using the SMCXFPMOD an XFP transciever is also required.
