OPGW Optical Ground Wire
OPGW Optical Ground Wire
Central Optical Unit Type Optical Unit In The Center Of Cable
Optical ground wire (OPGW) is a dual functioning cable. It is designed to replace traditional static/shield/earth wires on overhead transmission lines with the added benefit of containing optical fibers which can be used for telecommunications purposes. OPGW must be capable of withstanding the mechanical stresses applied to overhead cables by environmental factors such as wind and ice. OPGW must also be capable of handling electrical faults on the transmission line by providing a path to ground without damaging the sensitive optical fibers inside the cable.
The OPGW cable design is constructed of a fiber optic core (with single tube optical fiber unit depending on the fiber count) encased in a hermetically sealed hardened aluminum pipe with a covering of one or more layers of steel and/or alloy wires. Installation is very similar to the process used to install conductors, although care must be taken to use the proper sheave or pulley sizes so as not to cause damage or crush the cable. After installation, when the cable is ready to be spliced, the wires are cut away exposing the central aluminum pipe which can easily be ring-cut with a pipe cutting tool. The color-coded sub-units are preferred by most users because they make splice box preparation very simple.

FC Type
Fiber optic adapter, sometimes also called a coupler, is a small device designed to terminate or link fiber optic cables or fiber optic connectors between two fiber optic lines. It contains the interconnect sleeve that holds two ferrules together. By precisely linking two connectors, fiber optic adapters allow the light sources to be transmitted at their maximum and minimize the loss as much as possible. At the same time, fiber optic adapters have the advantages of low insertion loss, good interchangeability, and reproducibility. They are used to connect optical fiber connectors such as FC, SC, LC, ST, MU, MTRJ, D4, DIN, MPO, etc. They are widely used in optical fiber communications equipment, measuring appliances, and so on. The performance is stable and reliable.

FTTH Drop Cable Suspension Tension Clamp S Hook
FTTH fiber optic drop cable suspension tension clamp S hook clamps are also called insulated plastic drop wire clamps. The design of the dead-ending and suspension thermoplastic drop clamp includes a closed conical body shape and a flat wedge. It is connected to the body through a flexible link, ensuring its captivity and an opening bail. It is a kind of drop cable clamp that is widely used for both indoor and outdoor installations. It is provided with a serrated shim to increase hold on the drop wire and used to support one and two pair telephone drop wires at span clamps, drive hooks, and various drop attachments. The prominent advantage of the insulated drop wire clamp is that it can prevent electrical surges from reaching the customer premises. The working load on the support wire is effectively reduced by the insulated drop wire clamp. It is characterized by good corrosion resistant performance, good insulating properties, and long life service.

Ear-Lokt Stainless Steel Buckle
Stainless steel buckles are manufactured from high quality type 200, type 202, type 304, or type 316 stainless steel to match the stainless steel strip. Buckles are generally used for heavy duty banding or strapping. OYI can emboss customers’ brand or logo onto the buckles.
The core feature of the stainless steel buckle is its strength. This feature is due to the single stainless steel pressing design, which allows for construction without joins or seams. The buckles are available in matching 1/4″, 3/8″, 1/2″, 5/8″, and 3/4″ widths and, with the exception of the 1/2″ buckles, accommodate the double-wrap application to solve heavier duty clamping requirements.
