APT manufactures Fused Biconical Taper (FBT) couplers with industry-leading wavelength stability (±0.3nm) and insertion loss (<0.15dB). Our components enable precise signal splitting ratios from 1x2 to 1x64 for DWDM systems and PON networks. Featuring 900μm loose tube or 3mm armored cable options, APT FBT couplers operate across -40°C to +85°C with 0.02dB/km temperature-dependent loss. Trusted by tier-1 telecom operators for FTTH deployments.
APT’s 1x8/1x16 FBT splitters reduce passive optical network (PON) deployment costs by 22% through compact designs and pre-terminated pigtails. Our G.652.D compliant products ensure 0.4dB uniformity across 1260-1650nm spectrum.
APT’s hermetically sealed FBT couplers maintain <0.03dB/km performance in deep-sea environments. Borosilicate glass encapsulation prevents hydrogen-induced attenuation in undersea applications.
Our AI-driven inspection systems perform 100% IL/RL testing, achieving 99.998% defect-free rate. Real-time monitoring of taper profiles ensures consistent split ratio accuracy.
With polarization-dependent loss <0.05dB, our components enable precise photon distribution in QKD systems. Custom wavelength ranges from 780nm to 1550nm available.
