Timing & Synchronization Systems

Larus Corporation was founded in 1980 to manufacture telecommunications products for use by local telephone companies, long distance providers, and the public and private networks of North America.

Larus recognized that very early that Digital network connectivity is dependent upon the availability of a reliable synchronization source to provide a timing reference to the network elements and are now a recognized leader in the manufacture of sophisticated network timing and synchronization products. The products provide a complete range of the timing and synchronization products required to facilitate the efficient transmission of Digital signals. Larus timing products are deployed by Regional Bell Operating companies, Independent Telephone Companies, Competitive Local Exchange Carriers, government, utility companies,private communication networks, OEM manufacturers both domestically and internationally.

Larus products provide a full range of industry standard timing and synchronization systems, performing to Stratum1 Stratum 2 and Stratum 3E standards. These standards define the accuracy and "holdover" for the timing performance. Stratum 1 refers to an autonomous timing source such as an atomic clock or Cesium oscillator with no errors in 4 to 5 months. Stratum 2, 3, 3E etc normally track an input source, such as GPS. Should that source fail, the Stratum levels define the maximum allowable drift e.g 1.6 x 10-8 over a 1 year period.

Examples of the group's Timing and Synchronization products include:

54500:- An innovative Synchronization Timing System offering flexible and cost-effective solutions for Stratum 1, Stratum 2E, and Stratum 3E timing for digital transmission and synchronization applications. The system provides a redundant and jitter-free source of framed ones and composite clock and is synchronized to an equal or higher stratum framed reference source. The STS 54500 can be employed in either DS1 or E1 digital transmission environments.
5850:- Primary Reference Source. GPS timing clock designed for retrofits of existing BITS clocks and for remote sites that require timing.The STS 5850 features two accurate T1 timing references that are synthesized from GPS for use by BITS clocks, SONET NEs, intelligent multiplexers, and PCS systems as well as other systems requiring synchronization.
5800:- Timing System provides GPS Stratum 1 clock and/or network tracking with Stratum 2 or Stratum 3E holdover performance. The Larus 5800 represents the optimal local synchronization solution for the new distributed network. Designed for small installations and remote sites requiring timing (cell sites, PCS networks, customer premises, etc.).
