T8 and Corning Demonstrated a 100G Unrepeated Transmission over

500 km Using Corning’s Ultra-Low-Loss Optical Fiber (with ROPA)

CORNING, N.Y., September 17, 2012 -- T8 and Corning Incorporated (NYSE: GLW) demonstrated a dense wavelength division multiplexing (DWDM) system, transmitting 100 Gbit/s per channel over 500 km of Corning® SMF-28® ULL optical fiber without the use of regenerators or erbium doped fiber amplifiers.

This distinctive combination allows service providers and enterprises to drive new efficiencies by extending the unrepeated reach of high-capacity transmission over long distances without expensive regeneration.

The joint demonstration profiles T8’s high-quality 100G dual-polarization quadrature phase shift keying (DP-QPSK) transponder used on Corning’s ultra-low-loss fiber with a remote optical pumped amplifier (ROPA).

Corning’s SMF-28 ULL optical fiber features the lowest attenuation specification of any commercially available ITU-T Recommendation G.652-compliant fiber. In addition to enabling future network upgrades to 100G and more per single user, Corning’s SMF-28 ULL optical fiber maintains compatibility with the installed base of single-mode fibers.

“Corning is delighted to collaborate with T8 to demonstrate this complementary combination of 100G transmission equipment and Corning’s ultra-low-loss fiber,” said Sergey Akopov, technical director, Corning Optical Fiber. “Corning SMF-28 ULL optical fiber maintains higher signal strength; extends reach; and provides opportunities to reduce capital, operating expenses, and system complexity. As demand for high-speed broadband drives networks to higher capacity, it is exciting to demonstrate the efficiencies that SMF-28 ULL optical fiber contributes to network operations.”

“There are many long distance lines in Russia that might benefit from combining 100G DWDM transmission with the total capacity of 8 Tbit/sec and extremely-low-loss fiber,” said Vladimir Treshchikov, general director, T8. “To the best of our knowledge, this is the first successful demonstration of the transmission of 100G signal over the span of 500 km using ROPA. Operating over Corning SMF-28 ULL optical fiber allows our system to extend the unrepeated reach by 50-60 km compared to using standard single-mode fiber and makes unrepeated transmission over the distance of 500 km possible.”

T8’s innovative 100G transponder with optical-signal-to-noise (OSNR) tolerance of 12 dB can transmit 100G in most of the lines designed for 10G systems. T8’s newly released 100G product deploys advanced technologies as dual polarization QPSK modulation format, automatic dispersion compensation up to 75,000ps/nm, and SoftFEC algorithm.
