The OptiWay Premier Network Interface Device (NID) features an all-plastic enclosure designed to house electronic circuits for the growing FTTX and broadband access markets. The UL-listed NID can both replace and supplement existing fiber or standard copper NIDs. It is suitable for outdoor environments and utilizes a smaller enclosure to accommodate shrinking electronics for GPON, BPON, or EPON. The weather-resistant, flame-retardant, and impact-resistant NID also incorporates a hinged interface for access to OEM electronics, while improving the ability to dissipate heat when compared to standard NIDs. OptiFit Advantage drop cable assemblies allow for one-step installation of the subscriber drop, with no fusion splicing or field termination required at the subscriber premises.Corning Cable Systems,

Master Bond Polymer System EP37-3FLSP is an optically clear, flexible, low-viscosity, two-part epoxy system for large-volume castings. It features a long working life, low exotherm during cure, low shrinkage, and high dimensional stability. The EP37-3FLSP has a noncritical mix ratio of 2/1 by weight, and “pot life” after mixing exceeds 10 hours. Volumes larger than 1 gallon can be readily cast at room temperature without undue exotherm development. The epoxy exhibits excellent electrical insulation properties and high resistance to vibration, shock, and thermal cycling. It bonds to a variety of substrates including metals, glass, ceramics, most plastics, and many elastomers for applications in electronic and/or electromechanical devices, as well as optical assemblies and components.

Enhanced multimode fibers
Improved optical and geometric specifications for multimode fiber are intended to provide extra power “headroom” for demanding 1-Gbit/sec and 10-Gbit/sec premises applications, allowing for greater network design flexibility and reliability. For the line of 50-µm multimode fibers, including LaserWave OM3 fibers for 10-Gbit/sec transmission, the 850-nm attenuation specification has been lowered from <2.4 dB/km to <2.3 dB/km. For both 50-µm and 62.5-µm multimode fibers, the 1,300-nm attenuation specification has been lowered from <0.7 dB/km to <0.6 dB/km. The core/clad concentricity error in the multimode fibers has been decreased from <1.5 µm to <1.0 µm on both 50-µm and 62.5-µm fibers, allowing for better core-to-core alignment in connectors and splices and potentially reducing loss at these connections.

Utilizing a photon-bandgap technology platform, the “LDM” product series provides 10-Gbit Ethernet LX4 equipment manufacturers with single-wavelength lasers priced lower than a conventional DFB product. The LDM product set meets all requirements of the LX4 protocol, as defined in the IEEE 802.3ae-2002 standard, and utilizes four single-wavelength lasers operating at precisely defined wavelengths centered at λ = 1,275, 1,300, 1,325, and 1,350 nm, each operating at a data rate of 3.125 Gbits/sec, to provide an aggregate performance of 10 Gbits/sec across legacy Ethernet multimode cabling infrastructure. The lasers have stable temperature performance over a range of 0° to 85°C and typically feature side mode suppression ratios better than 35 dB.

Transport processor cores are available for OC-3 (XCS3F), OC-12 (XCS12F), OC-48 (XCS48F), OC-192 (XCS192F), and OC-768 (XCS768F) data rates. The SONET/SDH transport processor cores perform section and line overhead processing, align incoming SONET/SDH frames, and provide overhead interpretation with error detection and performance monitoring. The cores contain independent transmit and receive processors with optional dedicated external ports for overhead insertion and extraction. A generic register interface is implemented for access and configuration of internal memory mapped locations.

The VTXP-24 is an integral component of TranSwitch’s solution for next-generation multiservice provisioning platforms (MSPPs), packet add/drop multiplexing (ADM), and SONET/SDH optical edge devices. The device supports the Any Service, Any Port (ASAP) architecture along with the company’s PHAST-48V and VTXP-48 family of products. The ASAP architecture, with NPF-based APIs, supports full in-service, traffic-agnostic scalable data, and TDM switching and routing. The component can be used on any SONET/SDH or packet ADM system that requires bandwidth efficiency with VC-12/VT1.5 granularity. It can interface directly to SONET/SDH rings and provide hardware-based protection. In addition, it can interface to a multitude of framers or Ethernet and PDH mappers. The VTXP-24 also provides performance monitoring, intermediate path monitoring, and reporting capabilities on all virtual tributaries and SPE signals.
