(OTCBB OTCBB See OTC Bulletin Board (OTCBB). :DIGL DIGL Device Independent Graphics Layer ), a leading provider of optical networking test equipment and technology, today announced that NIC platform instruments can now be equipped with ODU-1 to ODU-2 Multiplexing capability, an industry first. The Optical Channel Data Unit (ODU) is part of the Optical Transport Network as defined in ITU publication G.709. The new Test Option enables NIC products to multiplex/demultiplex four ODU-1 signals within ODU-2 on Optical Channel Transport Unit (OTU)-2 interface. The NIC systems are used to confirm proper operation of network equipment during research and development, field implementation and ongoing maintenance. OTN networks are being implemented worldwide to provide robust and future-proof communications, with advantages such as Forward Error Correction A communications technique that can correct bad data on the receiving end. Before transmission, the data are processed through an algorithm that adds extra bits for error correction. If the transmitted message is received in error, the correction bits are used to repair it. (FEC), Tandem Connection Monitoring (TCM (1) (Trellis-Coded Modulation/Viterbi Decoding) A technique that adds forward error correction to a modulation scheme by adding an additional bit to each baud. TCM is used with QAM modulation, for example. ), network scalability, as well as efficient and transparent transport of multiple types of signals including SONET/SDH and Ethernet. "We are proud to be on the cutting edge of developing network technologies," stated Doyle Mills, Director of Product Marketing for Digital Lightwave. "The ODU-1 to ODU-2 multiplexing test capability finally provides network installers and equipment manufacturers the independent verification and analysis features they have needed for the lab, factory floor and field. This is one more example of how our flexible NIC platform, with its programmable technologies, allows the addition of extensive new feature sets. Our customers need test equipment that will grow with their needs and will have the features they need when they need them." The ODU-1 to ODU-2 Multiplexing Test Option is available on the NextGen Multi-Rate (NGMR) module. The NGMR supports 10GigE LAN (10.3Gbps), 10GigE WAN (9.953Gbps) and 10G FEC (11.049/11.095Gbps) in addition to SONET/SDH from 51Mbps to 10Gbps, and the OTN rates of OTU-1 (2.66Gbps) and OTU-2 (10.7Gbps). Additionally, the NGMR is designed for application in today's most advanced NextGen networks, supporting VCAT (Virtual Concatenation), LCAS (Link Capacity Adjustment Scheme Link Capacity Adjustment Scheme or LCAS is a method to dynamically increase or decrease the bandwidth of virtual concatenated containers. The LCAS protocol is specified in ITU-T G.7042. ), and GFP (Generic Framing Procedure Generic Framing Procedure (GFP) is defined by ITU-T G.7041. This allows mapping of variable length, higher-layer client signals over a transport network like SDH/SONET. The client signals can be protocol data unit (PDU) oriented (like IP/PPP or Ethernet Media Access Control) or can ). The NGMR module is available on all NIC[R] Platform products to enable single-module telecom/datacom testing.
