Besides, based on working wavelength differences, there are single window and dual window optical splitters-the former is to use one working wavelength, while the latter fiber optic splitter is with two working wavelengths.įBT splitter is based on traditional technology to weld several fibers together from the side of the fiber, featuring lower costs. The multimode optical splitter implies that the fiber is optimized for 850nm and 1310nm operation, whereas the single mode one means that the fiber is optimized for 1310nm and 1550nm operation. Besides, it has variously different split configurations, such as 1x2, 1x8, 2x32, 2圆4, etc.Īccording to the different transmission mediums, there are single mode optical splitter and multimode optical splitter. Fiber optic splitter box is usually used with 2mm or 3mm outer diameter cable, while the other is normally used in combination with 0.9mm outer diameter cables. The optical splitter can be terminated with different forms of connectors, and the primary package could be box type or stainless tube type. With the rapid growth of FTTx worldwide, the requirement for larger split configurations in networks has increased to serve mass subscribers. Its function is to split two incident light beams from two individual input fiber cables into sixty-four light beams and transmit them through sixty-four light individual output fiber cables. There are two input terminals and sixty-four output terminals in the optical splitter in 2圆4 split configurations. The optical splitter with 2圆4 split configurations is a little bit more complicated than the 1x4 split configurations. For instance, if the input fiber optic cable carries 1000 Mbps bandwidth, each user at the end of output fiber cables can use the network with 250 Mbps bandwidth. The 1x4 split configuration presented below is the basic structure: separating an incident light beam from a single input fiber cable into four light beams and transmitting them through four individual output fiber cables. Specifically speaking, the passive optical splitter can split, or separate, an incident light beam into several light beams at a certain ratio.
Therefore, the reallocation technique of optical signal can be achieved in multiple fibers, which is how fiber optic splitter comes into being. That is to say, if two fibers are close enough to each other, the transmitting light in an optical fiber can enter into another optical fiber. A small amount of energy will be spread through the cladding of the fiber. Generally speaking, when the light signal transmits in a single mode fiber, the light energy cannot be entirely concentrated in the fiber core.
