Shahid ghandi optical cable 4 core
OBUC Shahid Ghandi 4-core fiber optic cable is used in rural areas of telecommunication bases that have high humidity. The restraint wire used consists of 7 galvanized steel strands that are twisted and parallel to the cable core. Therefore, the cross section of the cable is considered as 8 Latin. Due to the presence of NZ for long distances and global communications, single mode fiber (4 * 1) is used and has a lower drop. This product also has a coating and is a product of Shahid Ghandi factory.
