generation network equipment. Filter WDMs: The company’s thin film filter based WDMs are used to combine and separate optical signals. Its filter-based products allow for higher isolation and narrower wavelength separations than fused fiber technology. Its filter WDMs are designed for a range of network applications, including combining active and passive components, and wavelength monitoring, splitting, and separating tasks. Amplifier Filter WDMs: The company’s amplifier filter WDMs are designed for a range of applications, such as splitting wavelengths and connecting lasers used in signal power amplification. DWDMs: DWDMs are integrated optical modules that combine, or multiplex, and separate, or demultiplex, multiple optical signals of different wavelengths on a single fiber. The company utilizes proprietary thin film technology in the development and manufacture of its DWDM products. CWDMs: CWDMs are integrated optical modules that multiplex or demultiplex multiple optical signals of different wavelengths on a single fiber. The company’s CWDM product separates wavelength into 20 nanometers, or spacing to cover the complete fiber optical communication spectrum from 1270 nm to 1610 nm. The company’s CWDM product covers 4 channel, 8 channel, and 16 channel mux and demux applications, and upgradeability for both 4 channel and 8 channel types. It also offers optical add-drop modules for CWDM networks, with the capability of adding or dropping from 1 to 15 channels. In addition to the CWDM mux, demux, and optical add/drop modules, it offers rackmount CWDM solutions to customers so they could mount its CWDM products directly on their system rack. Compact Coarse Wavelength Division Multiplexers (CCWDMs): CCWDMs are integrated optical modules that are designed to improve optical performance in a package approximately 1/4 the size of conventional CWDM modules. The company’s CCWDMs feature high wavelength accuracy and stability, low insertion loss, high isolation, low polarization dependent loss, and an epoxy-free optical path. Its Telcordia 1209/1221-qualified CCWDM builds on the company’s proprietary optical bench platform. With a channel spacing of 20 nm and bandpass characteristics, it allows for datacom or telecom network applications with uncooled lasers. These CCWDM Mux/Demuxes are available in 4 or 8 channels, and include an expansion port for 16 channel systems. Add/Drop DWDM Filters: Add/drop DWDM filter products are used to insert or extract specific wavelengths in a DWDM system. The company’s 200 GHz, 100 GHz, and 50 GHz add/drop components use filter technology and operate with optical power loss to provide channel separation and stability. Optical Isolators: These devices use polarization rotation to block return signals from the forward optical path. They limit distortions in devices and signals caused by reflected lights in the fiber. Optical Bypass Switches: These devices utilize beam shifting optics or mirror to switch optical signals from one fiber to another in response to a control signal provided electronically. Optical switches are used in test equipment for basic functionality and in networks to provide protection and redundancy. Automatic Variable Optical Attenuators: Automatic variable optical attenuators are designed to control the optical power in a fiber. They are combined with an active system component to maintain optical power on a network even if the input signal is changing power. The company’s automatic variable optical attenuators are designed for application in DWDM networks for use with individual channel source elements, such as add/drop transmitters. Customers The company sells its products to communications equipment manufacturers that incorporate its products into their systems that they in turn sell to network service providers. In certain cases, it sells its products to other component manufacturers for resale or inclusion in their products. Sales and Marketing The company’s direct sales force markets and sells its products primarily in the United States. It also maintains a sales support staff in Taiwan to service customers based in the Asia P
