Fiber optical attenuator,as an optical passive device, are used for optical communication system in the debugging of optical power performance, debugging of optical fiber instrumentation calibration,optical fiber signal attenuation. The attenuators are made using attenuated optical fibers doped with metal ions, which can adjust the optical power to the desired level.Metal MU male-female fixed attenuators offer excellent performance.
Fiber adapter with shutter, is a kind of adapter with laser radiation protection,with zirconia sleeve. implements connection of SC/LC fiber optic connector in the fiber optic cabling systems.It only produce a little loss for implementing optical path smooth. Simplex SC/LC fiber optic adapter couplers with side shutter makestwo end face precision docking, which can make light energy from transmitter optical fiber coupled to receiver optical fiber efficiently and will reduce impact to a minimum because of intervention optical link of the system.GoodFtth is offering shutter adapters for SC&LC types with different style,details please contact us anytime.
Ftta cable is a widely used for indoor and outdoor. In a base station signal transmission system, the cable from BBU to RRU is called the Ftta cable.The structure of the Ftta cable has a small outer diameter, softness, flexibility, saves laying space costs,excellent mechanical properties and environmental properties, and is widely used in 3G/4G/5G base stations.
Ftth Flat Indoor Drop Cable is known as indoor FTTHwiring cable. The dish-shaped leading-in cable (for indoor wiring) for the access network is made by placing the optical communication unit (opticalfiber) in the center, placing two parallel non-metallic strengthen member (FRP)or steel strengthen members on both sides, and finally, extruding black orwhite low-smoke halogen-free material (LSZH) sheath.
Commonly used flat drop cable is 1 or 2 core,can also be 4 core or multi-core structure, the cross section is shaped 8, the strengthen member is located in the center of two circles, can be used steel ornon-metal structure, the optical fiber is located in the geometric center of the shape of 8. The fiber is usually G.657,a small bending radius fiber.
