BOOKHAM TECHNOLOGY: Bookham Technology introduces multi-channel DWDM integrated Optical Channel Monitor AUG 29, 2000, M2 Communications - Denver -- Bookham Technology today introduces its new Optical Channel Monitor (OCM) with a live demonstration at the National Fiber Optic Engineers Conference (NFOEC) in Denver. The OCM is a multi-channel dense wavelength division multiplexing (DWDM) integrated optical component designed for use in systems with up to 40 channels. In July, Bookham Technology announced that it is supplying the OCM product to a major WDM customer. "The OCM is a key product in our DWDM portfolio which clearly demonstrates the multi-functional integration capabilities of ASOC," said David Gahan, director of DWDM products, Bookham Technology. The OCM is the first example of an arrayed waveguide grating (AWG) based product with added functionality - optical detection. It uses a series of integrated photodetectors that sample each channel simultaneously. This allows measurement of power to be made in real time, enabling channels in long-haul point-to-point or metro ring to be balanced by banks of electronic variable optical attenuators (EVOA). Since the OCM can monitor all DWDM channels simultaneously it can be used as an effective optical protection device, as any drop in signal strength can be detected, or simply as a monitor to allow network operators to keep track of which channels are in operation. The output of the OCM is in the form of electrical signals that can be fed back into the system for control purposes. Bookham Technology`s ASOC uses well-understood silicon manufacturing processes to produce integrated optical components. Their solid-state nature confers high reliability, whilst the manufacturing process lends itself to automation and volume production. ASOC also allows the integration of several optical functions on a single device as system architectures progress and the need for miniaturisation increases. Bookham Technology (LSE: BHM: Nasdaq: BKHM) designs, manufactures and markets optical components which allow communications networks to be constructed efficiently to meet the growing demands of Internet traffic. Using patented silicon-based ASOC technology, the company's products generate, detect, route and control light signals in the next-generation optical communication networks. The company, which is quoted on Nasdaq and the London Stock Exchange, is headquartered in the UK and has offices in the US, France and Japan.
