November 6, 2001 Santec has built on its expertise in the manufacture of passive optical components for DWDM applications and is pleased to announce the release of an integrated component that will enable the realization of compact reconfigurable add/drop devices. The new component, OAS-30, combines the functionality of a 2x2 optical switch, a variable optical attenuator, and a photodetector into a single compact, hermetically sealed unit. Multichannel add-drop modules which provide wavelength switching or routing functions generally consist of 2x2 optical switches, variable attenuators for power adjustment, and optical couplers and photodetectors for power monitoring. Such devices are increasingly being used as nodes in metro-core and metro-access systems. Santec?s OAS-30 combines this functionality into a single integrated device. The OAS-30 has the distinct advantages of reduced size, lower insertion losses, lower polarization dependent loss (PDL) and lower costs compared to conventional solutions. For example, an insertion loss of less than 1.4dB is achieved for the through channel, and a PDL of less than 0.25dB for the complete module. In addition, a single channel unit measures just 55x36x12 mm. In multi-channel applications, a complete 4 channel
module, i-OADM, with integrated Mux and Demux filters can also be
provided. Devices are available for both 100GHz and 200GHz systems
with a complete package size of only 185x150x25mm.
