FBT fiber couplers and PLC fiber splitters are two indispensable passive components essential for the distribution of optical signals in contemporary optical communication networks. Despite the fact that both devices serve the purpose of optical signal splitting, their application scenarios, performance characteristics, and manufacturing principles are substantially different.

FBT (Fused Biconical Taper) fiber couplers are manufactured by fusing and stretching two or more optical fibers under precise conditions. This conventional technology provides the benefits of low cost and the ability to accommodate division ratios of 1x2, 1x3, or 1x4. FBT couplers are effective in environments with limited temperature variation, short-distance transmissions, or small-capacity networks. Nevertheless, their performance may be compromised at wide wavelength ranges or increased split ratios, rendering them more appropriate for testing applications and fundamental fiber distribution networks.

Conversely, PLC (Planar Lightwave Circuit) fiber splitters employ sophisticated semiconductor photolithography technology to fabricate optical waveguides on a silica substrate. This structure guarantees a broad spectrum of wavelength compatibility (1260–1650 nm), exceptional stability, and uniform light distribution. PLC splitters are particularly well-suited for data center architectures, PON networks, and FTTH/FTTX projects, particularly when a high split ratio, such as 1x32 or 1x64, is necessary.

Hiphotonics Communications Co., Ltd., a company with over 21 years of experience in fiber optic fabrication, is a specialist in the production of both FBT and PLC splitters.. The company maintains stringent quality control systems, high-precision testing instruments, and advanced automated production lines to guarantee that each splitter complies with international standards, including GR-1209-CORE and GR-1221-CORE. The PLC splitters from Hiphotonics are distinguished by their compact design, high reliability, and low insertion loss. Meanwhile, the FBT couplers provide customized split ratios and an exceptional price-performance balance.

Hiphotonics guarantees the efficient, stable, and high-quality transmission of optical signals by offering customized fiber distribution solutions for data centers, telecommunications operators, and broadband access networks worldwide, backed by its robust R&D capabilities and adaptable production capacity.
