Adtran Inc. added ActivChassis stacking technology to its NetVanta 1600 series of Gigabit Ethernet switches, allowing network administrators to interconnect multiple switches and to view the stack as a single, logical chassis-like system, with control and management consolidated to a single viewpoint. ActivChassis technology will be available as a software upgrade for the NetVanta 1638 and the NetVanta 1638P Gigabit Ethernet switches sometime this month.
Netgear unveiled three 10 Gigabit Copper (10GBASE-T) switches for small and medium-sized businesses (SMBs) and other networks supporting fewer than 500 users. The products range from the lightly managed ProSafe 8-port 10 Gigabit Plus Switch (XS708E) for small networks to the ProSafe 12-port 10 Gigabit Smart Switch (XS712T) for small and medium-sized networks to the ProSafe 24-Port 10 Gigabit Copper M7100 series Managed Switch (XSM7224) designed for enterprise and campus-style networks. The switches range from $125 per port to $250 per port; Netgear says competing solutions can cost $415 per port or more. Research predicts 10GBASE-T switch shipments will see a 40-fold increase during the next five years due to more affordable, lower-power products becoming available.
Infinera wrapped what it says is the first successful demo of a 100 Gb/s optical signal enhanced with Soft Decision Forward Error Correction (SD-FEC) across Telstra Global’s dedicated fiber pair within Segment S5 of the AAG Hawaii-to-California submarine cable; the SD-FEC reportedly can double the transmission capacity of existing submarine cables. The trial used Infinera’s DTN-X platform and a prototype super-channel line card enabled with the company’s third-generation FlexCoherent processor. The SD-FEC allows higher-order modulation formats to be used, letting Telstra increase the available capacity on this link to service growing Internet demand.
3M calls its new portfolio of passive optical LAN solutions for the enterprise an “alternative” to traditional copper-based Layer 2 Ethernet switches. The products include high-performance fiber cable, “one pass” below-the-ceiling fiber pathways, and multifiber backbone trunks and MPO modules.
