Product Description

The 16FO (4x4) Indoor/ Outdoor Loose Tube Fiber Optic Cable SM G.657.A1 Dielectric Unarmoured (Part number: 60055664) from Prysmian with 16FO. Indoor/Outdoor fiber optic cable is prepared for both environmental requirements, indoor and outdoor optical networks, which can be run in duct, direct buried or aerial in the outside plant. By installing this cable, there's no need of costly splice junctions when entering into buildings because of the adaptability of the cable.

The 16FO (4x4) Indoor/ Outdoor Fiber Optic Cable G.657.A1 Dielectric Unarmoured from Prysmian is a Indoor/ outdoor cable with 16 fibers within 4 loose tubes. This distribution cable for optical networks has a loose tube structure and a HFFR compound with two ripcords beneath, on the inner and outer sheath with aramid yarns as peripheral strength elements. The Central resistant element is glass fibre reinforced with plastic rod (FRP), with plastic oversheathing when needed. The optical fibers comply with ITU-T recommendations G.657A1.

Fiber Type (ITU) - OS2 G.657.A1

Each type of single-mode fiber has its own area of application, and the evolution of these optical fiber specifications reflects the evolution of transmission system technology from the earliest installation of single-mode optical fiber to the present day. Choose the right fiber is very important for each project/installation. The OS2 G.657 standard single-mode fibers were developed to allow a better bending radius regarding the G.652 standard. For the OS2 G.657 fiber there are 4 subcategories: G.657.A1, G.657.A2, G.657.B2, G.657.B3. The G.657.A1 fiber type is characterized by 10 mm minimum bending radius. These specifications of the G.657 fibers allow to have a better cost-efficiency due to compact cable designs and reduced space requirements.

FOC Construction - Loose tube

While using a loose tube construction in cables, you can:

  • Pull and stretch without causing fractures from bending or tension;
  • Have full resistant protection of the fiber core, cladding and coating (mechanical protection and UV protection);
  • Reach optimized performances at extreme temperatures;
  • Avoid the risk of environmental damage (including water damage).

The loose tube construction solution can be chosen for the following applications:

  • Direct buried;
  • Aerial;
  • Duct;
  • Rodent resistant;
  • Indoor and outdoor;
  • Water-blocking;
  • Temperature endurance.
