Sunrise Telecom adds OTDR and fiber inspection to RxT for mobile backhaul test

December 17, 2011

In response to the increasing use of fiber optics in wireless backhaul networks as well as on cell towers themselves, Sunrise Telecom Inc. (OTC:SRTI) has unveiled the RxT-4000 Fiber Optics Toolkit (FOT) and the FiberScope inspection option to the company’s RxT Smart Productivity Test Platform. Sunrise Telecom also expects to the new modules to find use in networks using fiber to provide business and cloud-based services.

A pure Ethernet MAN can be highly cost-effective

December 16, 2011

Despite these shortcomings, non PBT/PBB enabled Ethernet-based MANs are used for two primary purposes: For small scale deployments (under a few hundred customers), a pure Ethernet MAN can be highly cost-effective. It also has the advantage of not requiring advanced knowledge of IP and related protocols, such as BGP and MPLS, which are necessary for an MPLS-based deployment.

Digital subscriber line access multiplexer

December 15, 2011

At the exchange, a digital subscriber line access multiplexer (DSLAM) terminates the DSL circuits and aggregates them, where they are handed off onto other networking transports. In the case of ADSL, the voice component is also separated at this step, either by a filter integrated in the DSLAM or by a specialized filtering equipment installed before it. The DSLAM terminates all connections and recovers the original digital information.

RAMPLAS effort seeks 100-Gbps optical RAM

December 15, 2011

A new project, partially funded by the European Commission under its Seventh Framework Programme (FP7-ICT-2009-C), will seek to develop a silcon-based optical random access memory (RAM) device capable of operating at 100 Gbps. The effort, called RAMPLAS, will seek to improve upon the access speeds now supported by Static RAM and DDR3 DRAM devices in a way that can keep pace with advances in processor speeds.
