SC/UPC Connector 1x4 PLC Fibre Optic Cable Splitter For FTTX
PLC splitter is a type of optical power management device that is fabricated using silica optical waveguide technology. It has the characteristics of small volume, wide operating wavelength range, high reliability, good uniformity of spectrophotometer and so on. For passive optical network (EPON, BPON, GPON, etc.) to connect the central office and terminal equipment and to achieve optical signal shunt. The 1xN and 2xN splitters evenly divide the optical signal into multiple outlets evenly from a single or dual inlet, or vice versa, to import multiple optical signals into a single or two root fiber.

According to the principle, optical shunt can be divided into fused tapered type and planar waveguide type. Two kinds, the melting pull cone type product is two or more optical fibers are fused by the side; Planar waveguide is a kind of micro optical component product, which adopts lithography technology to form optical waveguide on medium or semiconductor substrate to realize branch distribution function. These two types of spectrophotometric principles are similar. They achieve different branch quantities by changing the vanishing field coupling between optical fibers (coupling degree, coupling length) and changing the fiber radius. Conversely, it is also possible to combine multiple optical signals into one signal, which is called a synthesizer. Fused cone fiber coupler has become the mainstream manufacturing technology in the market due to its simple manufacturing method, cheap price, easy connection with external optical fiber as a whole, and can resist fu mechanical vibration and temperature changes and other advantages.
FBT Fused Fused conical Tap,Is to remove two (or more than two) coated layer of fiber in a certain way interference, melting under high temperature heating, at the same time to the two sides of the extension, finally in the heating zone to form a double cone form of special waveguide structure, through the control of fiber twist Angle and stretch length, can get different spectral proportion. Finally, the tapered area is cured on the quartz substrate with a curing adhesive and inserted into the stainless copper tube, which is the optical shunt. Due to the inconsistency between the thermal expansion coefficient of the curing adhesive and the quartz substrate and stainless steel tube, the degree of thermal expansion and cold contraction is not consistent when the ambient temperature changes. This situation is likely to lead to the damage of the optical splitter, especially when the optical splitter is placed in the field, which is also the main reason for the damage of the optical splitter. For more number of ways the divider production can be composed of more than two split circuit breakers.
Distribution of transmission signal with Fused taper Fiber divider (Fused Fiber Splitter) Fused taper technology is will be bound together two or more optical fibers, and then pull the cone machine melt stretching, and real-time monitoring the change of the ratio, spectral ratio requirements after molten stretching, one side retain a single Fiber (the rest of the cut) as input, the other end is a multi-channel output. At present, the mature taper drawing process can only pull less than 1 x 4 at a time. More than 1 x 4 devices, with more than 1 x 2 connected together. Then the whole package in the shunt box.
