Focus T1/E1 Multiplexers
FOCUS provides a flexible package for multiplexing virtually any type of signal or data directly onto fiber optic cables. Electrical interfaces to higher order multiplexing schemes such as M13, SDH or SONET (OC-3, OC-12, etc.) are also available. FOCUS drop and insert networks will work effectively with any combination of mixed communication links such as 1300/1550 nm single-mode fiber optics, SDH, SONET and digital microwave. This allows easy integration into existing systems. The drop and insert feature also improves channel conservation and eliminates the need for back-to-back channel banks. FOCUS offers four T1/E1 ports in one chassis, which can be fiber optic, electrical or a combination of both. Both features enhance the application of FOCUS for looped networks and loops with spurs.
