Fiber Optic Splitter For Passive Optical Network

Passive Optical Network (PON) fiber splitter plays a crucial role in Fiber for the network by letting a single PON network interface to become shared among many subscribers. A PON network could be made with an individual optical splitter, or it can have two or more splitters cascaded together. These are network elements that put the passive in Passive Optical Network are available in many different split ratios, including 1:8, 1:16, and 1:32. These communication networks have enhanced capabilities that can be relied upon to deal with high-bandwidth multimedia applications as well as prepare the network for increase in the long run.

Optical splitter Specifications
Optical splitters contain no electronics and make use of no power. An optical splitter is used to divide one particular optical fiber into separate strands, for the purpose of routing optical signals to multiple near end or remote locations. The Optical Splitter supports over 7,000 IP voice, data and video network connections to one Ethernet device. Optical Splitters are available in three different versions; as being a cable, being a tabletop enclosure, so that as a rack-mountable unit, all of which have superior design and are built from high quality components. The splitter can be deployed inside the Central Office (CO) alongside the OLT, or it could be deployed within an OutSide Plant (OSP) cabinet closer to the subscribers. A splitter may also be deployed in the basement of a building for a Multiple Dwelling Unit (MDU) installation.


Optical Splitters can be bought in configurations from 1×2 to 1×64. There are 2 basic technologies for building passive optical network splitters: FBT Splitter/Coupler (Fused Biconical Taper) and  PLC Splitter (Planar Lightwave Circuit). FBT Coupler could be the older technology and usually introduces more loss than the newer PLC splitter, though both PLC splitter and FBT splitters are widely-used in PON networks. FBT attenuation tends to be a little higher than attenuation from plc splitter.

FBT Splitter makes two (a couple of) fibers removed the coating layer gather within a certain way, stretched to each party within the heating zone at the same time, form a double cone?¡¥s special waveguide structure finally to get an alternative splitting ratio via controlling length of the fiber torsion angle and stretch. A FBT splitter is manufactured by wrapping two fiber cores together, putting tension on the optical fibers, after which heating the junction before the two fibers are tapered through the tension and fused together.

PLC Splitter is often a micro-optical element using photolithographic strategies to form optical waveguide at medium or semiconductor substrate for realizing branch distribution function. PLC Splitters are positioned in each optical network involving the PON Optical Line Terminal (OLT) along with the Optical Network Terminals (ONTs) that the OLT serves.

Optical splitters are traditionally used in Networks implementing BPON, GPON, EPON, 10G EPON, and 10G GPON technologies currently.
