AUGUST 16, 2007 -- Omron Electronic Components Business Europe (OCB-EU) will exhibit its range of optical communications devices, including optical switches, micro lens array (MLA) technology, PLC splitter modules, and what the company claims are the world's smallest CWDM multiplexer/demultiplexer devices.
CWDM muxes
Omron will display its P1X4, P1X8A CWDM Mux/Demux devices, which it claims are the world's smallest mux/demux devices for metro edge, storage, and access networks, including Gigabit Ethernet (GbE) and passive optical network (B, E, and GPON) applications. Measuring only 14.5- x 7.2- x 4.7-mm in size, the devices enable designers to realize very small form factor mux technology in their products, say Omron representatives. The company says the devices also offer ultra high reliability due to reduced number of parts and less complex active alignment processes during manufacture.
The components use a single-sided fibre array, helping to minimize thes pace needed for mounting and fibre routing/ bending radii. At the heart of the mux structure is an internal proprietary 2-P MLA, which provides precise "angled-path" optics of both the incoming and outgoing wavelengths, say company representatives.
Optical switches
Alongside the mux/demux devices will be Omron's family of P1S12-B and P1S22-B; 1x2 and 2x2 singlemode optical switches. According to the company, the products use "Precisely Arrayed and Combined Solutions" (PACS) fine replication and micro optics technology, including an MLA for cost efficiency and high performance.
The P1S12-B and P1S22-B feature a reduced typical insertion loss of justI0.8db and have working wavelength ranges to 1290-1360 nm and 1530-1625 nm. Use of replicated parts, including a magnetic mechanism together with a "VW" mirror system allows Omron to realize more reliable optical switch in a compact package size (31.6- x 12.6- x 8.4-mm), says the company.
PLC splitter modules
In addition, Omron will demonstrate its recently launched range of bi-directional PLC splitter modules targeted at FTTx PONs, DWDM, and CWDM systems, optical cable TV and other outside equipment applications.
Each device (1x4, 1x8 and 1x16, 1x32 and 1x64) is a packaged optical waveguide chip based on patented plasma chemical vapour deposition (P-CVD) technology. The combination of PLC structure and P-CVD process technology provides exceptionally stable optical characteristics and superior reliability compared with fused-fibre biconical taper (FBT) technology, OCB-EU representatives assert. The splitter modules exhibit low insertion loss, low polarization dependent loss, high port uniformity, and flat frequency response, adds the company.
