Fiber optic splitter

The fiber optical splitter, also named beam splitter, is founded on a quartz substrate of integrated waveguide optical power distribution device. The same as coaxial cable transmission system, the optical network system also needs to be an optical signal linked to the branch distribution, which necessitates the fiber optic splitter. It really is probably the most important passive devices in the optical fiber link. And it's also optical fiber tandem device with a lot of input terminals and many output terminals, especially applicable with a passive optical network (EPON, GPON, BPON, FTTX, FTTH etc.) to connect the MDF as well as the terminal equipment and also to achieve the branching with the optical signal.Optial splitter is used to split the fiber optic light into several parts at a certain ratio. Fiber optic splitters are essential passive components used in FTTX networks. There's two forms of fiber optic splitters(couplers) are popular used, you are the original fused typeoptical splitter (FBT coupler), featuring huge discounts; another is planar lightwave circuit splitter (PLC splitter), that is compact size and suit for density applications. Both of them have benefits to suit for several requirements.

FBT splitter makes two (a couple of) fibers removed the coating layer gather in a certain way, stretched to both sides beneath the heating zone at the same time, form a double cone special waveguide structure finally to get an alternative splitting ratio via controlling entire fiber torsion angle and stretch. FBT splitter can be a traditional type with more than Twenty years history. It's a mature product. And it is low priced and straightforward to create, but fused fiber optic splitters optical loss are sensitive to wavelength and this is among its big disadvantages.

PLC splitter is a micro-optical element using photolithographic techniques to form optical waveguide at medium or semiconductor substrate for realizing branch distribution function. The PLC splitters are developed based on silica glass wave-guide process with reliable precision aligned fiber pigtail. PLC fiber optic splitters are small size and wide working wavelength. They are more reliable, suitable for use in passive optical network fiber optic splitting. PLC splitter can be used to distribute or combine optical signals. It really is according to planar lightwave circuit technology and offers an inexpensive light distribution solution with small form factor and high reliability.

Fiber optic splitters may be terminated with different forms of connectors, the key package could possibly be box type or stainless tube type, you are usually used with 2mm or 3mm outer diameter cable, another is usually used in combination with 0.9mm outer diameter cable. And based on working wavelength difference, you can find single window and dual window fiber optic splitters (Dual Window FBT Coupler). And there are single-mode and multi-mode fiber splitters. Typical connectors installed on the fiber optic splitters are FC or SC type.

The largest fiber optic products supplier FiberStore now provides all kinds of fiber optic splitters. There are PLC splitters for sale in the flexible type of 1U 19" rackmountable box, and come with Fan-out kits and terminated, the sort of blockless with terminated or unterminated ends and small plastic ABS box for use outdoors and standard LGX metal box. And that we likewise have FBT couplers with various types for your traditional requirements.
