Highly integrated for Ethernet PON, the PAS6201 optical-networking-unit system-on-a-chip (SoC) is optimized for high-bandwidth customer premises installations on FTTH networks delivering services like high-definition TV, voice over IP, interactive gaming, and other high-bandwidth services over a single connection. It incorporates a CPU, media access controller, SerDes, Layer 2+ switch, and packet buffer on a single chip. Conforming to the recently ratified IEEE 802.3ah standard for Ethernet in the First Mile, the SoC is shipped with a complete, modular FTTH software stack based on an open source Linux platform, reducing time-to-market for system developers while enabling them to add functionality.

Originally designed for 3-mm cable, the re-designed singlemode SC connectors meet the requirements and objectives Telcordia GR-326 to optimize performance on 1.6- to 2-mm cable. Using components similar to other small-form-factor connectors, they also incorporate six-position tuning to optimize fiber alignment. Complete testing was performed at Intertek Testing Services NA, an independent laboratory. Supplemental data was collected at 1490- and 1625-nm wavelengths for fiber to the home, optical service channels, and other L-band applications. The configuration tested was a simplex SC connector, which was terminated to 1.6-mm simplex cordage that contained standard, matched-cladding fiber. Use of this fiber, instead of a bend-insensitive type, confirms that the connector’s design performs reliably, even when external loads are applied.

The MD1231A1 fully portable self-contained Ethernet performance test system with support for two 10-Gigabit Ethernet (10-GbE) ports, Layer 3/IP testing, and 1-msec bandwidth measurement resolution can significantly reduce test time on multiport products such as switches and routers. The two 10-GbE ports also allow the system to function at both ends of a test network, transmitting and receiving traffic simultaneously at full wire speed. Flexible and expandable, the tester supports any combination of two Ethernet or packet over SONET (PoS) modules, including 1-GbE, 10-GbE, 2.5-Gbit/sec PoS/Ethernet over SONET, and 10-Gbit/sec PoS. For physical line and media-converter testing, the tester’s packet and unframed bit-error-rate test capabilities verify PRBS integrity in all Layer 2 and IP interface payloads. The small, lightweight tester weighs 13 lb, measures 12.6×4×11.8 inches, and incorporates a Windows-based PC, display, and pointing device.

For outside plant crews installing and maintaining optical-fiber cables in broadband, metro, access, and FTTH networks, the OFL 200 handheld OTDR combines full/semi-automation mode for operators not familiar with OTDRs with the ease of use of manual mode for experienced users. It provides an integrated 650-nm visual fault locator with a universal adapter for short-distance troubleshooting and fiber tracing. The fast-change switchable adapter allows the OTDR to interface launch cables with a variety of connector styles. The rugged, lightweight 1550-nm singlemode tester locates reflective and non-reflective breaks and provides a wide temperature range (−10° to +50°C). It also features a large LCD with backlight; Windows-compatible software to view, print, and archive test records; cursor and zoom controls to measure event loss, reflectance, and location; rechargeable NiMH battery pack, AC adapter, or AA alkaline; switchable OTDR port adapter; and >70-km effective range.

Based on Impact Mount Technology (IMT), the Field Repair Splice makes fiber cable repair operation and training easy because it is mechanically tool-driven. The splice can handle the pull strength of Kevlar during operation, which is the cable typically used with remote-controlled robots. Insertion loss is typically <0.3 dB. The splice offers quick emergency repair and restoration for security equipment and machinery, particularly during cable deployment for data telecommunications and for biochemical sensors. Technicians in the field can make repairs to the fiber cable and be back in operation within minutes. Other key applications include emergency fiber cable restoration for tactical robots, broadcasting, and movie productions, along with temporary communications networks where the fiber is deployed on the ground and has the potential to be damaged. The installation kit is compatible with certain ST, SC, FC, and SMA connectors.

The enhanced ONS 15530 DWDM platform with high-density storage and multiprotocol service aggregation capabilities provides users the flexibility to meet a broad range of disaster recovery and business continuity requirements, from the core of enterprise data centers to remote branch offices. The comprehensive SAN extension portfolio includes metro DWDM, storage over SONET/SDH, and Fibre Channel (FC) over IP solutions. Two new line cards provide four-port 1- or 2-Gbit/sec FC/Ficon aggregation for higher service density over extended distances and a eight-port multiservice muxponder to support storage, data, voice, and video services over a highly available DWDM network. This protocol and data-rate flexibility meets the service requirements of managed service providers and enterprises through a single, scalable platform that supports low-speed, legacy services such as T1/E1 or Fast Ethernet as well as high-speed newer services.

Based on the new LAN/PHY architecture for video on demand networks, the PLEXiS GXTX-9180 transmitter, GXRX-9182 receiver, and GXTR-9184 transceiver use 10-Gbit/sec short-reach XFP pluggable optics for LAN side connection. The WAN side link is provided by ITU grid DWDM optics, which offer link distances exceeding 600 km. Extensive monitoring capability for Ethernet statistics is available for the transmitter, receiver, and transceiver.

For metro and long-haul service-provider networks, the flexible TM-DXFP 10-Gbit/sec transponder supports both STM-64/OC-192 and 10-Gigabit Ethernet (10-GbE) protocols and can span distances of up to 80 km over G.652 fiber-optic cable without the need for amplification or dispersion compensation. It is a single-slot module that interfaces between the CWDM or DWDM multiplexers and 10-Gbit/sec terminal equipment. The transponder module uses XFP 10-Gbit SFP transceiver receptacles to provide increased flexibility in choosing the optical interface of the terminal equipment. By using the XFP receptacle, the same transponder can support any possible optical interface. The transponder metro-distance (40-km) and long-haul (80-km) versions support both GbE and SONET/SDH.

Designed to comply with the SFP multisource agreement (MSA), the SFP-155E electrical transceiver delivers full-duplex STM-1 electrical (155-Mbit/sec) SDH transport over coaxial cables. The hot-pluggable module is fully interchangeable with STM-1 optical SFP modules, delivering instant STM-1 electrical support-any system that already supports STM-1 optical can now support STM-1 electrical. Additionally, a single card can support both optical and electrical STM-1 interfaces. The electrical interface is fully compliant with ITU-T G.703 (ES1) recommendations and can be connected using standard DIN 1.0/2.3 75-Ω cable connectors. Serial identification (EEPROM) in accordance with the SFP MSA is available. Typical applications include next generation SDH add/drop multiplexers, optical edge devices, multiservice provisioning platforms, and switching systems. The transceiver was designed under a development partnership agreement with AimBridges.
