KimI have cooperated with Yuantong company for many years, they have good quality cables and after-sale service.I buy their FTTH drop cable most , and my clients are also be satifised with the products.
SunI have visted the Yuantong Company, they gave me good feeling at Chengdu city. We checked many companys and finnally decided to cooperated with them . The optical cables shows that this decision is right ! Their cables are used on construction and workers saied the cables are very nice!

Composite OPGW Fiber Optic Cable,
om4 OPGW Fiber Optic Cable,
OPGW om4 fiber optic cable
OPGW Mainly used for power communication with accessories,relay protection,automatic transmission,installation together with high-voltage lines.
The central stainless steel tube is surrounded by single or double layers of aluminum clad steel wires(ACS) or mix ACS wires and aluminum alloy wires. are the most widely used cables ,their design is fully adapted to the most common electric line needs.
Fiber Type: G652D; G655C; 657A1; 50/125; 62.5/125; OM3; OM4 As Options
● Replacement of existing ground wires and reconstruction of old lines.
● Applicable to low-grade lines, such as GJ50/70/90 and etc.
● Small cable diameter, light weight, low additional load to the tower;
● The steel tube locates at the center of the cable, no second mechanical fatigue damage.
● Low resistance to side pressure, torsion and tensile (single layer).
