Cable Construction and Parameter

Overhead ground wire made of aluminum-clad steel wire (AS) and stainless steel tube containing optical fiber.

3.2Cable type: OPGW-48B1.3-190[205;185.4]

3.2.1 Cross section of OPGW

Specification of OPGW

Fiber and Loose Tube Color Identification

The individual fiber and loose tubes shall accordance with standard TIA/EIA-598-A and the color code as below.

Steel tube 1 (No.1-12 fibers) : Single mode optical fiber (SM)

Fiber Colors

Steel tube 2 (No.13-24 fibers) : Single mode optical fiber (SM)

One black tracer (50mm pitch)

Steel tube 3 (No.25-36 fibers) : Single mode optical fiber (SM)

One black tracer (100mm pitch)

Steel tube 4 (No.37-48 fibers) : Single mode optical fiber (SM)

One black tracer (150mm pitch)

Packing and Shipping

The OPGW shall be tightly and uniformly wound on a strong wood-iron reel which conforms to ANSI/AA 53-1981 or equal. The reel shall be lagged with stout wood-iron battens so as to prevent the OPGW from damage in ordinary shipping, handling, storage and stringing operations.

Drawing of Reel

According to length of cable, we choose different type reel (D,d,b,w1,w2) for loading cable.

Environmentally

Full comply with ISO14001, RoHS and OHSAS18001 system

Installation Recommendations

Installation procedure:

It is recommended that IEEE Std 524-1992 and our company recommended procedures be used for the installation of OPGW.
