Los Angeles, USA — March 27^th, 2007— PhoXtal Communications AB, developer of integrated optical components for communications networks demonstrates its Monolithically Integrated FTTH Diplexer Array at this year’s OFC Conference in Anaheim, California.  
 
PhoXtal’s FTTH Diplexer Arrays combine 4, 8 or 12 diplexers in the same chip.
 
Single-step low-cost fabrication
The Diplexer Array is based on PhoXtal’s fabrication method for 1310/(1490)/1550 bidirectional diplexers (triplexers) where transmitters, receivers and wavelength selective couplers are integrated into one InP (Indium Phosphide) device. The fabrication cost is reduced by using a single epitaxial growth layer. In each diplexer, WDM functionality is achieved with a coupler designed for a large optical bandwidth, the laser by forming a DFB emitting directly into the waveguides, and standard receivers consisting of WG-PD (Waveguide Photo Diodes) implemented in the waveguides. A Diplexer Array with 250 μm fiber attachment spacing is achieved with a selected number of parallel diplexers on the same chip.
 
Dramatic improvements in port density
PhoXtal’s Diplexer Arrays are intended to be implemented in QSFP (Quad (4-channel) Small Form factor Pluggable, www.qsfpmsa.org) packages. By connecting MPO-connectorized fiber arrays in a point-to-point FTTH installation directly into the central office equipment, the port density of the equipment can be increased by a factor of three or more.
 
Visit PhoXtal at OFC 2007 booth 3261 for a demonstration of the Monolithic FTTH Diplexer Array.

Quintech Electronics introduces their new TXS/RXS 2150 8:1 Fiber Link Redundancy System. The TXS/RXS 2150 8:1 Fiber Link Redundancy System provides the routing mechanism for substituting a backup fiber link for any one of eight main fiber links. In essence, this system provides highly reliable fiber redundancy for 1/8^th the cost of installing a redundant fiber link for each primary link.

“Redundancy can be expensive, but this new system represents the most cost effective fiber link redundancy solution on the market. It enables customers to deploy redundancy at a fraction of the cost of 1 to 1 redundancy applications.” said G. Daniel Prushnok, President and CEO.

Quintech provides state-of-the-art proprietary hardware solutions (DC-40 GHz) to facilitate RF signal management in complex telecommunications networks. Quintech specializes in RF matrix switches, routers, splitters, combiners, frequency converters, relay switches, redundancy switches, line amplifiers and DC powering products for broadband cable/HFC, Satellite L-band and Intermediate Frequency applications.

The RGB-5000 from Multidyne provides a long haul, transport solution for high-quality, up to 1600 by 1200, high-resolution, RGB or VGA video sources via ONE fiber.  The RGB-5000 performs a horizontal gen-lock for a fully synchronous and jitter free high resolution video transport.  The system has been upgraded to support a higher quality image at higher resolutions such as 1600 by 1200. The Video and Synch jitter has been reduced to as low as 4 to 5 nano seconds.  The net result is a crystal clear image at all resolutions and refreshes rates.  The improvements have also extended the operational temperature range to -20 to 60 degrees C.  

The RGB-5000 provides a total analog bandwidth of up to 600 MHz.  The system 1600 by 1200 pixels are supported over ONE optical fiber.   The supports standards include RGB, XVGA, SVGA, UXGA, Component and Analog HDTV signals. 
The RGB-5000 has a data throughput of 3.125 Giga Bits per second.  Most systems have a 1.25 Gb/s data throughput with 60% compression.  

Daisy-chain one RGB/UXGA source to multiple monitors with the NEW MultiDyne RGB-5000-DC RGB/UXGA Fiber Optic Transport Systems with Daisy-Chain.  The receiver unit includes an optical repeater to re-transmit the optical RGB/UXGA signal to the next monitor in the chain.  Distribute one High Resolution, RGB/UXGA Video signal from one point to multiple points.  

Now the user can distribute a high resolution video signal using one fiber optic transmitter to many receivers.  The user now can save the cost of duplicate transmitter units, passive and active splitters and add/drop devices.  Each RGB-5000-FRX-DC receiver unit includes a fiber optic input and output.  Internally the fiber optic input is decoded for the local monitor and then repeated for re-transmission to the next monitor in the chain.   The system can virtually repeat a high resolution video signal indefinitely.
