The fiber optical splitter, also called beam splitter, is one of the most important passive devices in the optical fiber link. It is a fiber optical tandem device with many input terminals and output terminals, especially applied to a passive optical network to connect the MDF and the terminal equipment, to achieve the branching of the optical signal. There are two kinds of fiber splitters that are popularly used: One is FBT coupler (Fused Biconical Taper) and the other is PLC splitter (Planar Lightwave Circuit) . Today I would like to introduce you the PLC splitter.
PLC Splitter, based on silica optical waveguide technology and precision aligning process, dividing a single/dual optical input(s) into multiple optical outputs uniformly, which is denoted 1×N or 2×N. Nowadays, PLC splitter is widely applied in FTTX developments, PON networks, CATV links and optical signal distribution, meets these various application requirements in different environments. PLC Splitter offers superior optical performance, high stability and high reliability, excellent uniformity over a wide wavelength range from 1260nm to 1620nm and working in temperature from -40C to +85C. The PLCS devices have standard configurations of 1×4, 1×8, 1×16 and 1×32 configurations, as well as customized structures of 2×8, 2×16, 2×32 and 2×64.
PLC splitters contain of three main parts: an input fiber array, a planar light-wave chip, and an output fiber array. All three PLC splitter components have to be very precisely aligned so that we could guarantee the best possible transmission characteristics: low insertion loss per channel (minimally exceeding the theoretical values), low back reflection loss, consistency and very high uniformity of transmission parameters per channel within complete spectrum of transferred optical signal wavelengths and for all states of polarization.
Advantage and Disadvantage:
PLC Splitter advantage: Loss is not sensitive to the wavelength of the transmitted , to meet the transmission requirements of different wavelength, spectral uniformity, the average signal assigned to the user, compact structure, small volume, low cost of more points, the more obvious cost advantage.
PLC Splitter disadvantages: the device fabrication process complexity, high technical threshold.
The PLC Splitters are key components used in FTTx networks. Ingellen supplies the PLC splitters including 1XN to 64 and 2XN to 64 types, they are with a wide range of working wavelength for different applications. The PLC splitter can be with optional various kinds of connectors and cable length, they feature compact size and very good optical performance. All products meet GR-1209-CORE-2001 and GR-1221-CORE-1999 requirements. More, Ingellen can customize optical splitter to suit your exact conditions.
