Optoplex Readies Filters
The 2-port tunable filter modules designed and assembled by Optoplex in Fremont of California have undergone a qualification program to ensure the long-term reliability of the TF assembly based on the Telcordia GR-468-CORE requirements. Mechanical Shock, Vibration, Fiber Integrity, Temperature Cycling, Damp Heat, Low Temperature Storage, High Temperature Storage and Thermal Shock tests have all been completed. The qualification results show the high mechanical integrity and environmental durability of the tunable filter devices that further ensures the manufacturability of Optoplex's optical tunable filter products.
Optoplex's optical tunable filter modules are based on its patented micro-optics design, a high-precision micro-actuator, and its state-of-the-art thin-film optical coating. The standard TF family supports 50- and 100-GHz channel spacing, operating in C- or L-band wavelength range. The tunable filter products are widely applied in fiber-optic communications networks, including dynamic wavelength selection in DWDM systems, signal demultiplexing for DWDMs, optical performance monitoring, tunable optical noise filtering, noise suppression for optical amplifiers, etc. The qualified tunable filters feature an athermal design, wide tuning range, C- or L-band coverage, flat and wide passband for up to 40 Gb/s signal, low & uniform insertion loss, high channel isolation, latching, hitless, and low power consumption.
