Optical amplifier offers record low noise, says Chalmers researchers

September 15, 2011

Researchers at Chalmers University of Technology in Sweden say they have demonstrated an extremely low noise optical amplifier that can extend signal reach by 4X. The phase-sensitive fiber-optic parametric amplifier (PSA) offers a noise figure of 1.1 dB, 3X less than that of conventional EDFAs. If the amplifier can be commercialized – and Chalmers described the technology behind the PSA as “practical” – it could significantly improve the performance of optical communications networks by lessening the amount of interference signals would encounter.

GigOptix sampling LX8220 40G TFPS modulator

September 15, 2011

GigOptix, Inc. (OTCBB:GGOX) says it has begun sampling its LX8220 Thin Film Polymer on Silicon (TFPS) Mach-Zehnder modulator used for 40-Gbps applications based on the differential quadrature phase-shift keying (DQPSK) modulation format.

In another sign that coherent technology is ramping up, NeoPhotonics Corp. (NYSE:NPTN) says it has quadrupled manufacturing capacity for its Integrated Coherent Receivers (ICR) for 40- and 100-Gbps coherent fiber-optic transport systems.

JGR Optics offers MS12001 mandrel-free cable assembly test system

September 15, 2011

JGR Optics Inc. has released the MS12001 Mandrel-Free Cable Assembly Test System. The system includes the MS12 Mandrel-Free IL/RL Test Module Series, designed to provide accurate insertion loss and reflectance measurements with enough sensitivity to enable mandrel-free reflectance measurements down to -80 dB on cable lengths as short as 1 meter. The test and measurement system also includes the MS7 Series of modular optical switches and a new family of modular platforms, the MS05P, MS10P, and MS10E.

GigOptix tests polymer 40G Mach-Zehnder modulator with Tier 1 optical transponder manufacturers

September 15, 2011


GigOptix, Inc. (OTCBB:GGOX) says that it has crossed a pair of items off its “to do” list as it prepares the LX8401 40-Gbps Mach-Zehnder modulator for commercialization. First, “a number” of Tier 1 customers have validated the the fiber-optic component's performance in system-level tests. Second, the LX8401 has completed the High Temperature Operating Lifetime (HTOL) reliability assessment of Telcordia GR-468 without operating performance degradation.
