Lightweight FTTH Flat Drop Cable G657A1 G657A2 Fiber 1 2 4 6 8 12 Core
Description
G657A1 G657A2 1 2 4 6 8 12 Fiber Indoor FTTH Flat Drop Cable manufactured by ANC International Co., Limited is a kind of special curved optical fiber, which providing greater bandwidth and enhanced network transmission characteristics. This cable replaces the standard copper wire of the local Telco as it can carry high-speed broadband services integrating voice, data and video, and runs directly to the junction box at the home or building. ANC supplies FTTH Indoor Cable, FTTH Drop Cable, FTTH Duct Armored Cable, etc. In order to cut inventory costs and speed up the installation process for our customers, ANC’s FTTH cable designs can simplify your project. FTTH Indoor flat drop cables are used internally in buildings or for residential applications. In the center of the cable is the optical fibers, with the two parallel non-metal enhanced FRP as the strength member, and surrounded with the LSZH jacket. Indoor FTTH cables have the same function as common indoor fiber cables, but also have some special features. FTTH indoor cables are smaller in diameter, soft and bendable. They are easy to deploy and maintain.
