Sommer Cable Octopus Hybrid PUR 443 and 244

Share this Post:

Sommer Cable is offering its new Octopus Hybrid PUR 443 fiber-optical hybrid cable line, pictured left, for control applications or for transmitting AES/EBU (or DMX) signals. Along with the 443, which combines four OM3 multi-mode fiber optics with three power supply wires and two signal pairs, the company is also offering its reworked Octopus Hybrid PUR 244, pictured below right, with two single-mode fiber optic lines and two power wires plus two signal pairs. Both the PUR 443 and 244 are touted for their light weight, compact size and rugged design features.

More details from Sommer Cable (www.sommercable.com):

Octopus Hybrid PUR 443 consists of four OM3 multi-mode fiber optics (50/125 µm – 10 GBASE-SR over 300 m, 1000 BASE-SX over 900 m; breakout design with special aramid threads as strain relief and direct connector assembly), three power supply wires with 2.5 mm² (nominal voltage 300 / 500 V, brown/blue/green-yellow) plus two signal pairs (2 x 2 x 0.22 mm²).

The whole construction is surrounded by a dense aramid mesh and fitted with a cold-flexible PUR jacket. There are extra aramid yarns in the central elements for strain relief. The maximum tensile load of the cable is 600 N. With a outer diameter of 13.4 mm and only 190 g/m, the cable is compact and lightweight, enabling Sommer Cable to offer systems with 100 m cable length on the compact HT481 drum from Schill at a total weight of less than 30 kg.

Sommer Cable Octopus Hybrid PUR 244Sommer Cable’s reworked Octopus Hybrid PUR 244 is based on the SMPTE 311M standard that is widely used in the broadcasting sector. The Octopus Hybrid PUR 244 houses two single-mode fiber optics (9/125 µm, breakout design with proprietary aramid threads), two power supply pairs, each with AWG20 (color coding black/white) and two signal pairs (2 x 2 x 0.22 mm²). With a central aramid element and an overall aramid mesh the reworked cable design achieves a higher maximum tensile load of 600 N. The cable with an outer diameter of 9.2 mm has been optimized for the SMPTE 311 connector. The cable weight is only 133 g/m.

Sommer Cable’s Octopus Hybrid 443 cable is also available as a fully pre-made system. Here the Straubenhardt-based manufacturer relies on the modular HAN-ECO connector from the Harting company. The smallest possible connector housing with three module slots takes up the fiber-optical module (4 x SC-Ferrule), one Power/AF module plus the PE module, and the housing is only 80 mm wide. The multipin’s big advantage is that all connections (fiber-optics, mains supply and signal) are established via a single plug-in procedure, and the cable end is equipped with a efficient strain relief. Users seeking a robust breakout solution can pair this pre-made system with Sommer Cable’s The Boxx floor stagebox.

Of course, the cable ends can also be configured completely to individual customer requests; e.g. they can be spliced up to LC, SC or ST and certainly to a multi-fiber connector (HI-Fiber4 or expanded beam connector), too.

Typical applications for the systems would be:

– Connection of digital FOH places via a single cable

– Connection of e.g. entire A/D converter racks in mobile recording via a single cable

– In- and outdoor transmissions (ENG/SNG) over long distances
