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, 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.
