Devices utilize PACS technologyOmron has announced a family of fiber-optic switching components, offering reduced insertion loss and higher repeatability meeting the demanding applications of Ring Protect, Optical Add and Drop (OADM) and signal monitoring in Data and Telecommunication access networks.

The new devices are P1S12-B, P1S22-B and P1S18-B, which are 1x2, 2x2 and 1x8 single mode optical switches. Each device utilize the company's Precisely Arrayed and Combined Solutions (PACS) fine replication and micro optics technology, including a Micro Lens Array (MLA) for cost efficiency combined with very high performance.

Designed for the replacement of electric switches in access networks, the P1S12-B/ P1S22-B feature a reduced typical insertion loss of 0.8db, compared with 1.2/ 1.5dB previously. Other improvements include expansion of working wavelength ranges to 1,290 1,360nm and 1,530 1,625nm.

The press release explained that the use of replicated parts, including an innovative magnetic mechanism together with a "VW" mirror (prism) system, has allowed Omron to realize a proven, high reliability optical switch in a package size that measures 31.6(L)-by-12.6(W)-by-8.4(H)mm. Operating life has also been extended, with the components now rated for 10 million mechanical operations. The company added that the P1S18-B is one of the smallest of its type as it measures 93.5-by-16-by-8.5mm. Developed around an all-new purpose-made linear actuator coupled to a precisely aligned prism, it achieves a typical insertion loss of 2dB. An integrated calibration sensor tracks actuator function and together with a highly advanced latch system achieves fine mechanical adjustment whilst suppressing vibration effects. This in turn helps to maximize repeatable optical performance even in portable applications.

The P1S18B is specified for wavelengths between 1,290nm to 1,360nm, 1,530nm to 1,565nm, and 1,625nm to 1,675nm. All 1x2 and 2x2 Switches are offered with bi-stable (latching feature) to minimize power consumption. Non-latching versions are also available on request at no additional cost. The 1x8 switch has a bi-stable function.
