Enhanced broadband service routers
New 10-Gigabit Ethernet (10GbE) and high-density Gigabit Ethernet interface cards help reduce the cost and complexity of deploying IPTV and other multiplay services with the E320 Broadband Services Router. The 10GbE service cards enable cost-effective high-bandwidth connections between the E320 and downstream Ethernet aggregation devices as well as upstream core routers. The eight-port high-density GbE cards distribute multicast processing to the line cards, reducing load on the switch fabric and line modules, which helps providers increase system scalability while improving performance.

The GETF-110 series of Gigabit Ethernet copper-to-fiber media converters offer Transparent Link Pass Through and Remote Fault Detect, which prevent them from isolating a head-end device from link failures at the remote end by monitoring the status of both the copper and fiber links. The converters pass link status information on to both end devices, notifying them of the link failure. Users can choose between fixed fiber interfaces and an open SFP slot. Converters with an open SFP slot support multimode, singlemode, or long-haul singlemode fiber transmissions based upon the individual SFP module used in the converter.

The ClearSpectrum-DCMX chromatic dispersion compensation module boasts the industry’s smallest package and offers enhanced performance for high-speed metro and long-haul DWDM networks. It is designed to compensate links from 20 to 200 km in a single, low-loss module. The module is intended as an alternative to dispersion-compensating fiber (DCF) in cost-sensitive networks since its small footprint minimizes space and its low insertion loss (<3 dB) reduces amplification requirements. Based on multichannel fiber Bragg grating technology, the compensators can be cascaded in networks beyond 2,000 km.

The Splicer V-Groove cleaning kit integrates eight components for inspection and cleaning of any fusion splicer. Contamination in the v-groove of the splicer is still a primary source of trouble for the splicing technician. This is especially problematic when splicing with a fixed v-groove fusion splicer. The kit’s cleaning fluid is nonflammable and environmentally safe, and lint-free cotton swabs are included for cleanup without generating additional particles. Refill kits are also available for the fluid and cleaning tools.

Following the release of the PHY1078 GEPON chipset, the PHY2078 transceiver IC is designed for the higher-bandwidth 2.5-Gbit/sec GPON ITU G.984.2 standard. It can be combined with a microcontroller to support digital diagnostic monitoring (DDM). The PHY1095 and PHY1097 transimpedance amplifiers are capable of high-sensitivity performance without the added cost of an avalanche photodiode circuit. The PHY1097 is designed for GEPON and GPON operating at up to 2.5 Gbits/sec, with sensitivity of -29 dBm and low input referred noise of 150 nA. The PHY1095, which operates at up to 1.25 Gbits/sec, servicing the GEPON sector of the market, achieves -32-dBm sensitivity coupled with 60 nA of input referred noise.
The ML9xx46 series, a high-output laser diode for use in optical fiber communication capable of 2.5-Gbit/sec transmission, is targeted for FTTH and GPON applications. By optimizing the construction of the active layer where the laser diode emits light, the diode shows improved optical conversion efficiency at high temperatures with an optical output of 15 mW and operating range of -40° to +85°C. Modulation bandwidth has been improved by reducing the capacitance of the laser diode. An aspherical lens increases coupling to 70% in the ML920T46S model. This decreases operating current, which leads to reduced power consumption in the transmitter.

The new BERTScope S pattern generator allows design and test engineers to generate calibrated, stressed data for jitter tolerance testing when either the device under test or a legacy bit-error-rate tester (BERT) are used to measure bit-error ratio. The pattern generator supports testing for sinusoidal jitter, sinusoidal interference, bounded uncorrelated (PRBS) jitter, and random jitter. With very flexible clocking capabilities from 0.1 to 12.5 Gbits/sec, it can also stress an external clock, including spread spectrum clocks (SSC) for serial bus testing. It is capable of flexible pattern generation with intuitive RAM pattern editing and a library of common standards patterns such as Fibre Channel, Serial ATA, and others.

Patented FiberFinder technology, including both the LFD-300 Live Fiber Detector and the TG-300 Tone Generator, takes the guesswork out of fiber identification for the efficient and safe management of live and dark optical fibers. Disconnecting the wrong fiber can cause significant network downtime. Installed at the transmitter site, the TG-300, a nonintrusive clip-on device, adds a 0.1-dB signature to the live signal by applying a soft, low-frequency modulation pressure to the fiber. If it’s a live fiber, the signature will be detected by the LFD-300 at the other end in seconds, removing the risk of disconnecting the wrong fiber. The detection devices show little or no effect on a link’s loss budget, which is important for large central offices and FTTX applications with high numbers of fibers.
