FREMONT, CA – Primanex Corporation, a provider of highly reliable optical devices based in Fremont, California, has introduced a new 2x2 magneto-optical (MO) switch with smooth transient behavior today. The most notable feature of this switch is the output optical power transient characteristics. In particular the sum of two output channels never drops more than 5 dB relative to the total input power, and after switching the cross talk of the switch is still below –50 dB. This switch can be used in all optical amplifiers to suppress power transient caused by adding and dropping channels during normal operation and by channel failure. This transient behavior is made possible by a proprietary magneto-optical technology innovation from Primanex. Further benefits from this technology include: very fast switching speed in the range of 0.5 milliseconds; very compact size of the device; and excellent reliability due to the all solid-state design. One sample has gone through over 2 billion switching cycles without any degradation in optical performance.In a separate release:

FREMONT, CA – Primanex Corporation, a leading provider for fiber optical devices, introduced today an innovative, super reliable and low cost electronically controlled variable optical attenuators (EVOA) based on a proprietary, patent-pending Magneto-Optic (MO) technology with no moving parts. The high reliability, great optical performance, and low cost make it a top choice for all EVOA applications, such as EDFA gain control, ROADM and channel equalization, etc. This new product not only inherits the highly reliable feature of Primanex’ previously released product, the optical switches, but also achieves a huge reduction in material cost and electric power consumption. More importantly, the assembly process for this product is designed to be supported by the automation equipment available in the market.Primanex’ CTO, Dr. Hongdu Liu, emphasized that “Besides super reliability, Primanex’ EVOA also has top performance in all major technical specs, including a large attenuation range (0.8 up to 45 dB), a low polarization dependent loss (PDL < 0.2 dB at 20 dB, <0.1 dB at 10 dB attenuation), a high attenuation accuracy (0.1 dB at 20 dB attenuation), and a small footprint. The small dimension of the device allows conveniently packing individual EVOAs into an EVOA array with any number of channels. The unique design allows us to firmly believe that our manufacturing cost is lower than ANY competing company can claim.” Primanex plans to showcase both products at their booth #1650, in Hall D at OFC 2002, from March 19 to 21 in Anaheim Convention Center.
