OMRON has released fibre-optic switching components that offer reduced insertion loss and higher repeatability, meeting the demands of applications including ring protect, optical add and drop and signal monitoring in data and telecommunication access networks.
The P1S12-B, P1S22-B and P1S18-B 1x2, 2x2 and 1x8 single-mode optical switches use Omron’s precisely arrayed and combined solutions (PACS) fine replication and micro optics technology, including a micro lens array (MLA) for cost efficiency and high performance.
The P1S12-B and P1S22-B are designed for the replacement of electric switches in access networks. They have a reduced typical insertion loss of 0.8db and their working wavelength ranges have been expanded to 1290nm – 1360nm and 1530nm – 1625nm. Use of replicated parts, including magnetic mechanism together with a “VW” mirror (prism) system, has allowed Omron to provide an optical switch in a package size of 31.6mm x 12.6mm x 8.4mm. Operating life has also been extended, with the components now rated for 10 million mechanical operations.
The P1S18-B measures 93.5mm x 16mm x 8.5mm. It was developed around a purpose-made linear actuator coupled to a precisely aligned prism, achieving a typical insertion loss of 2.0dB.
An integrated calibration sensor tracks actuator function and together with a latch system it achieves fine mechanical adjustment whilst suppressing vibration effects. This in turn helps to maximise repeatable optical performance even in portable applications. The P1S18B is specified for wavelengths between 1290nm - 1360nm, 1530nm - 1565nm, and 1625nm – 1675nm.
All 1x2 and 2x2 switches are offered with a bi-stable latching feature to minimise power consumption. Non-latching versions are also available at no additional cost. The 1x8 switch has a bi-stable function.
