Description

Designed for stable optical signal distribution, this PLC ( planar lightwave circuit) Fiber Splitter delivers low insertion loss, excellent channel uniformity, and wide wavelength compatibility.Featuring ultra-low insertion loss as low as 3.8dB for 1×2 configurations, excellent channel uniformity within ±0.3dB, and a wide operating wavelength range of 1260nm to 1650nm. This PLC fiber splitter delivers reliable signal transmission with minimal attenuation across all output ports. These core advantages help telecom operators reduce signal loss, improve network stability, and support long-distance fiber transmission in high-density optical distribution networks.

Designed for modern fiber optic infrastructure, the planar lightwave circuit splitter supports multiple split ratios including 1×2, 1×4, 1×8, 1×16, 1×32, 1×64, and 2xN configurations. The compact structure simplifies installation in optical distribution frames (ODF), fiber distribution boxes, splice closures, rack-mounted systems, PON networks and FTTH access terminals.
