What is an optical splitter?


An optical splitter, also called an optical beam splitter, is an integrated waveguide power allocation device that divides an input optical signal into two or more output optical signals. Optical splitter is a passive device. It has no electronic devices and no power supply. It is an important component of passive optical networks (such as EPON, GPON, FTTx, FTTH, etc.). At present, the splitting ratio of optical splitter is generally 1:4, 1:8, 1:16 and 1:32. In the WDM system, demultiplexer is used to divide the optical signals of different wavelengths into corresponding wavelength channels, while the optical splitter divides the whole optical signal into multiple channels for transmission. An optical splitter divides an input light signal into a plurality of output light signals with a certain splitting ratio. For example, an optical splitter with a splitting ratio of 1:4 can divide an optical signal into four parts on average, and then transmit it in four different channels. In addition, optical splitter can also end connector types, the package is usually a cassette or stainless steel tube two, cable box splitter generally use 2mm or 3mm diameter stainless steel tube, cable and optical splitter generally use 0.9mm diameter.
Characteristics of optical splitter:
The use of single / multimode fiber and polarization maintaining fiber multi port design, cable length and diameter can be customized with a plurality of light splitting ratio, from 1:99 to 50:50 package into the tube and cassette, a fused biconical taper (FBT) optical splitter and planar waveguide type optical splitter (PLC) connector two terminal are PC, UPC and APC three lapping modes may be terminated FC, SC, ST, LC and MU connectors.
