Fiber optic channel

This type of cable is generally used in intra-city networks and between telecommunications centers.

Based on the request of the applicant, other cable structures can also be produced.

This type of cable has a different structure and is not jelly or dry. It is used to protect the cable against moisture penetration.

Based on the requirements of the applicant, other cable structures can also be produced.

The general information of this type of cable is presented in the table below.

Structure of dry channel optical fiber cable (OCUC)

1- Central resistant element: non-metallic central resistant element (FRP) with a minimum average diameter of 2.5 mm.
2- Moisture absorbing yarn: The moisture absorbing yarn is spirally placed on the central resistant element.
3- Core: The loose tubes are wrapped around the central resistant core with a left and right turn. PP or HDPE fillers may be used in the cable structure to match the looseness of the tubes with the central element.
4- Moisture absorbent tape: A layer of moisture absorbent tape with sufficient thickness surrounds the loose tubes lengthwise. The overlap should not be less than 3 mm.
5- Intermediate resistant element: a layer of aramid yarn is overlapped lengthwise on the moisture absorbent tape for additional tensile force.

6- Peeling thread: Two peeling threads are placed on both sides of the cable diameter on the moisture absorbent tape and under the outer cover. The peeling thread must be strong and flexible enough to cut tape or polyethylene.
7- External/outer coating: A black HDPE coating covers the aramid yarn. The average coating thickness is 2 mm.
