— 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.
