Studio or Remote Environments

In the hybrid 311 format, the HD video 

signal is transmitted over two single-

mode optical fibers to ensure accurate and 

extended-distance data transmission. To 

increase the durability, a special nylon-

based polymer with increased tensile 

strength is used for the fiber coatings, 

and a 16 AWG steel strength member is 

cabled at the center of the cable core. All 

copper elements feature heat-resistant 

PE insulation and a shielded copper braid. 

The HDC920 comes in an extra-flexible, 

abrasion-resistant TPE compound that 

is ideal for portable, studio and outdoor 

broadcast applications, while a flexible 

PVC jacket is used for HDC920R and 

HDC920P for riser and plenum permanent 

installation applications. Designed for 

permanent underground installation, 

the HDC920PEF has an extra-rugged 

polyethylene jacket and water-blocking 

tape wrapped around the cable core.
