Figure 8 drop with steel wire 4 fibers

Figure 8 drop with steel wire 4 fiber also called self-supporting central tube aerial fiber optic cable, is a cable type for outdoor optical fiber network wiring. It uses 4 core optical fiber, Figure 8 -shaped design, which makes it more convenient when hooking or laying. At the same time, the cable has also increased steel wires to provide better tensile tolerance and protect the optical cable damage from the external environment.

REVIEW

APPLICATION

Applied outdoor, for installation on the telecommunication supports, between the buildings and industrial constructions.

Applied indoor, for cable tray distribution networks of fiber optics. It is allowed to lay cable on the outdoor.

Steel wire strand self-supporting drop cable is an affordable, small, self-contained fiber optic cable that is more suitable for external use over longer distances than FTTH Drop Cable. Jera Line is a Chinese factory specializing in the production of optical cables and can provide accessories such as optical cables . clamp and steel strips.

TEST

Fiber optic core reflection test is proceed by Optical Time Domain Reflectometer (OTDR). Which is a device used to precisely detect faults in an optical fiber link of a communication networks. An OTDR generates a pulse inside a fiber to be tested for faults or defects. Different events within the fiber create a Rayleigh back scatter. Pulses are returned to the OTDR and their strengths are then measured and calculated as a function of time and plotted as a function of fiber stretch. The strength and returned signal tell about the location and intensity of the fault present. Not only maintenance, but also optical line installation services utilize OTDRs.

OTDR is useful for testing the integrity of fiber optic cables. It can verify splice loss, measure length and find faults. The OTDR is also commonly used to create a "picture" of fiber optic cable when it is newly installed. Later, comparisons can be made between the original trace and a second trace taken if problems arise. Analyzing the OTDR trace is always made easier by having documentation from the original trace that was created when the cable was installed. OTDR show you where the cables are terminated and confirm the quality of the fibers, connections and splices. OTDR traces are also used for troubleshooting, since they can show where breaks are in fiber when traces are compared to installation documentation.

Jera proceed test of FTTH drop cables on wavelengths (1310,1550 and 1625 nm). We use EXFO FTB-1 in this quality tests. Examining the quality of our cables to ensure ours customer could receive products which meet quality requirements.

We do this test on every cables we produce.
Our internal laboratory is capable to proceed such a series of standard related type tests.
