1x4 Blockless PLC Splitter

1x4 Blockless PLC Splitter, G.657.A1 Single Mode Fiber Splitter

The Firsol 1x4 Blockless PLC Splitter is a compact single-mode passive optical component designed to divide one input optical signal evenly into four output channels. Manufactured using silica-based planar lightwave circuit technology, it provides stable optical performance over a wide operating wavelength range of 1260–1650 nm. The splitter uses bend-insensitive G.657.A1 fiber and features insertion loss of ≤7.4 dB, loss uniformity of ≤0.6 dB, low PDL of ≤0.2 dB, return loss of ≥50 dB, and directivity of ≥55 dB. With a maximum optical power capacity of 500 mW, it is suitable for FTTH, PON, CATV, telecommunications networks, and optical signal distribution systems. Custom fiber lengths and LC, SC, FC, or ST connectors with UPC or APC polish are available to meet different installation requirements.
