Fiber-optic cable glut forces companies to step up R&D

August 25th, 2009 Posted inGAO Comm News

Following an oversupply last year, fiber-optic cable companies in mainland China this year are concentrating on developing new products and widening their overseas markets.

The Ministry of Commerce has passed a measure ordering foreign fiber-optic manufacturers who intend to enter the mainland China market to pay anti-dumping tax ranging from 8 to 46 percent for a period of five years. The ministry earlier declared that foreign fiber-optic makers are dumping their products in the country.

The new measure aims to stabilize mainland China’s fiber-optic industry, which has been experiencing a surplus in inventory despite the high demand for fiber-optic cables driven by the FTTH technology. Last year, output of fiber-optic cables in mainland China was 20 million kilometers, exceeding the market requirement of 14 million kilometers to 16 million kilometers.

This year, only a few makers are expected to expand their production capacity while the majority will focus on developing new products. For instance, Jiangsu Zhongtian Technology Co. Ltd (ZTT) is concentrating developing RF cables, as well as new cables using micro-cable systematic technology.

The company has entered into a US$15-million joint venture with Hitachi Cable and the Nanjing University of Posts and Telecommunications to establish Zhongtian Hitachi Radio Frequency Cable Co. Ltd, which will focus on the research and manufacture of coaxial cable for 3G applications.

Last year, ZTT manufactured 19,000km of OPGW cables and 38,000km of ADSS cables. Both of the company’s ADSS and OPGW cable output grabbed a 35 percent share of the total market in mainland China. ZTT exports its products to more than twenty countries in North and South America, Europe, the Middle East and Southeast Asia.

Another maker, Wuhan-based FiberHome Telecommunication Technologies Co. Ltd has developed double-cladded Ytterbium-doped fibers (DCYF) with an output power of 100W and 400W. The company has an annual capacity of 3 million fiber-optic cables.

Plug-in Fixed Attenuators for Power Regulation in Optical Systems

August 24th, 2009 Posted inGAO Comm News

Toronto, Canada –GAO Comm has announced the availability of its plug-in fixed attenuators used in optical systems where the optical power from a source is too high for the test equipment in use. The attenuator is an electronic device that reduces the amplitude or power of a signal without appreciably distorting its waveform. It introduces an in-line fixed loss that will reduce the source power to an acceptable detection level. This attenuator is suitable for use in telecommunication networks, optical fiber CATV, measuring instruments, local area networks, optical fiber sensors and optical fiber to household systems. It is also deployed to lower voltage, dissipate power and improve impedance matching.

These attenuators are optimized for doped fiber technology and manufactured with various specifications such as different connector types and end face configurations. The easy-to-install electronic units enjoy high stability, low insertion loss and precise attenuation. They work at wavelengths from 1260nm to 1620nm with a maximum handling power of 1W.

MRV Fiber Driver Platform Delivers Green Optical Networking Based On New Carrier Standard

August 24th, 2009 Posted inGAO Comm News

CHATSWORTH, CALIF.–(BUSINESS WIRE)–

MRV COMMUNICATIONS, INC. today announced that its Fiber Driver optical multi-service platform delivers a highly energy efficient optical networking solution for carriers when evaluated using the Telecommunications Equipment Energy Efficiency Ratings (TEEER) standard developed by Verizon. MRV is a leading networking company with a full line of packet-optical transport (POTS), carrier Ethernet, 40G networking and out-of-band networking products.

The TEEER score is defined as a direct relationship between the system forwarding capacity and its power consumption, weighted for different operation modes. Verizon’s calculated TEEER value represents the system energy efficiency rating on a scale from one (least efficient) to 10 (most efficient). More information on the TEEER standard can be found at www.verizonnebs.com/TPRs/VZ-TPR-9207.pdf.

In certain configurations, MRV’s Fiber Driver platform achieved a score of 9.78, showing the WDM optical transport system to be a power-optimized solution for carriers. The Fiber Driver platform packs up to 600 Gbps in just 3U of rack space. With a power consumption of three to five watts per 10Gbps interface, it consumes only 20% to 30% of the power that competing optical transport systems need.

MRV’s Fiber Driver product line provides differentiated services including fiber grooming (media conversion, distance extension and signal repeating), converter-based service demarcation, advanced CWDM and DWDM solutions and digital video distribution. The Fiber Driver platform can act as a media converter, a repeater or a WDM transponder with a simple change-out of hot-swappable multi-functional modules. The Fiber Driver provides a wide range of optical transport solutions to enterprise, campus and metro networks with distances of 80-100km.

“Energy efficiency is a concern for all industries today and a lot of vendors are claiming to be green,” said Noam Lotan, president and CEO of MRV Communications. “The beauty of the TEEER standard is that it gives a benchmark that customers can use to compare systems from different vendors in an objective way.”

Verizon’s efficiency rating system is part of its energy consumption standards developed in the wake of government initiatives driving carriers toward more environmentally friendly networks. The goal of the standard is to improve energy efficiency in the equipment the company buys by 20% over today’s networking equipment.

Mars lander’s 1st soil sample may not be analyzed

August 19th, 2009 Posted inGAO Comm News

SAN FRANCISCO (Reuters) – Dirt that the Phoenix Mars Lander scooped recently from the planet’s surface may be too clumpy to be analyzed by the machine’s onboard system, NASA reported on Saturday.

A robotic arm retrieved a cup-sized sample of Martian dirt on Friday and placed it on the lander’s Thermal and Evolved-Gas Analyzer, or TEGA, which was scheduled to spend about a week determining the soil’s water and mineral content.

The TEGA features a screened opening that prevents large particles from clogging it. Only those thinner than 1 mm (0.04 of an inch) can pass through, and an infrared beam verifies whether they have entered the instrument.

The beam has not yet confirmed any activity and researchers are not sure why, NASA said in a statement.

Scientists suspect the soil may be clumped together too tightly, NASA said.

“In the future, we may prepare the soil by pushing down on the surface … then sprinkle a smaller amount over the door,” Ray Arvidson, the team’s science lead, said in the statement.

Engineers are also looking for a way to shake some of the current sample down into the TEGA oven, where it would be heated and analyzed.

Scientists may send instructions to vibrate the compartment after they inspect the problem for a day or two, spokeswoman Sara Hammond said.

The lander will also gather other soil samples, examine them with a microscope and mix them with water to determine their composition, Hammond said.

The $420 million lander spent 10 months journeying from Earth and touched down on Mars 12 days ago. Its three-month mission was proposed after the Mars Odyssey detected frozen water below the Martian surface in 2002.

This is the lander’s first attempt to analyze soil, which might contain salt left behind by evaporated water or ice.

The single-use compartment will go unused if scientists are unable to coax any particles to fall down, but there are seven others like it onboard, Hammond said.
