  • Global Opticom Releases Programmable Optical Add/Drop Multiplexer
Jun 2001
SUNNYVALE, Calif., June 6 -- Global Opticom has unveiled a programmable optical add/drop multiplexer (OADM). The programmable OADM combines thin-film dense wavelength division multiplexing and optomechanical switch technologies with an electronically controlled interface. It can dynamically add, or drop, any and all operating channels remotely, or on the board, using built-in software. A series of programmable OADMs (4 x 4, 8 x 8, 16 x 16, and 20 x 20) with 50-, 100- and 200-GHz ITU grid spacing-for both C- and L-bands can be provided.
    Since the programmable OADM has an all-optical path configuration, SONET/SDH, Gigabit Ethernet, video signal, etc., can pass through, or drop, without optical/electrical, or electrical/optical, conversion. A system operator can build an all-optical switching network, making a system more efficient, flexible and cost-effective.
