Xtellus is a leading supplier of ROADM technology and dynamic optical modules for Agile Optical Networking systems. Agile Optical Networks are reconfigurable DWDM networks that are used to provide rapid provisioning and efficient operation of triple-play high-speed Internet, video and telephone services.
Xtellus is headquartered in Morris Plains, NJ, with manufacturing and development facilities in Israel and South Korea. Xtellus market leadership is based on:

A broad family of ROADM products including wavelength selective switches, wavelength blockers and ROADM modules with integrated power monitoring and muxes/demuxes.

Proprietary liquid crystal optical processors that are the dynamic optical engines at the heart of all Xtellus products. These processors can be configured to switch, pass-through or block, attenuate or selectively filter light. They can handle hundreds of wavelengths concurrently and with no moving parts have ultra-high reliability.

Patented product designs that provide and protect the multiple advantages of Xtellus products such as low insertion loss combined with high extinction, precision filter shapes, compact module size and manufacturing techniques that support very competitive prices.

Rapid product customization obtained by leveraging Xtellus' in-house liquid crystal optical processor fabrication facility - the only one of its type in the world dedicated to telecommunications applications - and an integrated dynamic optical module manufacturing line.

A dynamic leadership team that combines outstanding optical networking business expertise and optical module design and manufacturing expertise.
