2 Fiber Core FTTH Drop Fiber SM G.657 (A1、A2 、B3）Corning FRP Strength Member, LSZH Butterfly Flat Indoor FTTH Drop Cable GJXFH
GJXFH FTTH Indoor Drop Cable with butterfly flat structure,
With Two parallel Fiber Reinforce Plastic (FRP) strength members with LSZH sheath and 1 or 2 or 4 or… Optical fiber unit is positioned in the center. FTTH indoor cable because of Fiber Type Singlemode G.657A has a much greater bandwidth to carry data and less susceptible to interference than common indoor fiber cables because flexibility of Singlemode G.657A1 bendable characteristics. With small diameter, water-resistant, the non-metallic strength member FRP (Fiber-reinforced plastic) can provide lightning protection and anti-electromagnetic interference. FTTH cables are ideal for indoor cabling, end users directly cabling, and access network. The optical fiber unit is positioned in the center. Two parallel Fiber Reinforced Plastics (FRP) are placed at the two sides. Then, the cable is completed with a black or white LSZH sheath.
1)on fiber type G652D or G657A,Pls note that drop cable usually using G657A Fiber, because G657A Fiber have more small bending radius than G652D,Even both type fiber have same grade attenuation. But Drop cable using for FTTX project, and this project require some point with very small bending radius. If you using G652D will cause too big attenuation or fiber will broke if you bend too small radius .please understand it is very important on this issue.
2)On the center strength member, better using FRP .If you using steel wire will cause the arrestor lighting go into home and will big risk for people.so better using FRP and make sure safety

What’s the difference between PVC and LSZH cables
Physically, PVC and LSZH are very different. PVC are very soft; LSZH are more rigid because they contain the flame retardant compound, and they are aesthetically more pleasing. A PVC cable (made of polyvinyl chloride) has a jacket that gives off heavy black smoke, hydrochloric acid, and other toxic gases when it burns. Low Smoke Zero Halogen (LSZH) cable has a flame-resistant jacket that doesn’t emit toxic fumes even if it burns.
The telecommunications industry differentiates between several distinct FTTX configurations. The terms in most widespread use today are:
FTTP (fiber-to-the-premises): This term is used either as a blanket term for both FTTH and FTTB, or where the fiber network includes both homes and small businesses.
FTTH (fiber-to-the-home): Fiber reaches the boundary of the living space, such as a box on the outside wall of a home. Passive optical networks and point-to-point Ethernet are architectures that are capable of delivering triple-play services over FTTH networks directly from an operator’s central office. FTTB (fiber-to-the-building, -business, or -basement): Fiber reaches the boundary of the building, such as the basement in a multi-dwelling unit, with the final connection to the individual living space being made via alternative means, similar to the curb or pole technologies.
FTTD (fiber-to-the-desktop): Fiber connection is installed from the main computer room to a terminal or fiber media converter near the user’s desk.
FTTO (fiber-to-the-office): Fiber connection is installed from the main computer room/core switch to a special mini-switch (called FTTO Switch) located at the user´s workstation or service points. This mini-switch provides Ethernet services to end user devices via standard twisted pair patch cords. The switches are located decentrally all over the building, but managed from one central point.
FTTE / FTTZ (fiber-to-the-telecom-enclosure or fiber-to-the-zone) is a form of structured cabling typically used in enterprise local area networks, where fiber is used to link the main computer equipment room to an enclosure close to the desk or workstation. FTTE and FTTZ are not considered part of the FTTX group of technologies, despite the similarity in name. FTTF (fiber-to-the-frontage) This is very similar to FTTB. In a fiber to the front yard scenario, each fiber node serves a single subscriber. This allows for multi-gigabit speeds using XG-fast technology. The fiber node may be reverse-powered by the subscriber modem. FTTdp (Fibre To The Distribution Point) This is very similar to FTTC / FTTN but is one-step closer again moving the end of the fiber to within meters of the boundary of the customers premises in last junction possible junction box known as the “distribution point” this allows for near-gigabit speeds FTTN / FTTLA (fiber-to-the-node, -neighborhood, or -last-amplifier): Fiber is terminated in a street cabinet, possibly miles away from the customer premises, with the final connections being copper. FTTN is often an interim step toward full FTTH (fiber-to-the-home) and is typically used to deliver ‘advanced’ triple-play telecommunications services.
FTTC / FTTK (fiber-to-the-curb/kerb, -closet, or -cabinet): This is very similar to FTTN, but the street cabinet or pole is closer to the user’s premises, typically within 1,000 feet (300 m), within range for high-bandwidth copper technologies such as wired ethernet or IEEE 1901 power line networking and wireless Wi-Fi technology. FTTC is occasionally ambiguously called FTTP (fiber-to-the-pole), leading to confusion with the distinct fiber-to-the-premises system.
FTTA (fiber-to-the-Antenna) in 3G and 4G BTS
To promote consistency, especially when comparing FTTH penetration rates between countries, the three FTTH Councils of Europe, North America, and Asia-Pacific agreed upon definitions for FTTH and FTTB in 2006, with an update in 2009, 2011 and another in 2015. The FTTH Councils do not have formal definitions for FTTC and FTTN.
