Bare Fiber PLC Splitter

Utilizing bend-insensitive single-mode fiber compliant with ITU-T G.657A1 standard, the additional loss at 1550nm wavelength under 10mm bending radius is ≤0.5dB, significantly reducing microbending loss risks compared to traditional G.652D fiber.

This characteristic is particularly important in space-constrained scenarios such as high-density cabinet cabling, fiber storage in splice closures, and corner routing, preventing link loss increases or signal interruptions caused by excessive fiber bending.

Meanwhile, it maintains excellent compatibility with G.652D fiber, ensuring seamless integration with existing networks.

Under 1×32 splitting configuration, typical insertion loss is ≤16.6dB (including connector loss), approaching the theoretical splitting loss value of 10×log₃₂≈15.05dB, with excess loss controlled within reasonable range.

Uniformity ≤1.5dB ensures minimal optical power variation among the 32 output ports, preventing imbalanced scenarios where "remote users experience weak signals while nearby users receive excessive power."

SC/APC angled polishing achieves ≥55dB return loss, effectively suppressing back-reflected light's impact on laser stability, protecting central office OLT equipment and improving system signal-to-noise ratio, especially suitable for high-speed PON systems and CATV analog signal transmission scenarios.

The 1260~1650nm wide operating wavelength range covers O-band, C-band, and L-band, supporting multi-wavelength multiplexing applications including 1310nm upstream, 1490nm downstream, and 1550nm video overlay.

Wavelength-dependent loss (WDL) ≤0.5dB ensures minimal loss variation across different wavelengths after splitting, meeting coexistence requirements for multi-generation technologies like GPON (1310/1490nm), XG-PON (1270/1577nm), and 10G-EPON (1270/1577nm).

Polarization-dependent loss (PDL) ≤0.3dB has minimal impact on polarization-sensitive high-speed coherent optical signals, reserving sufficient margin for future network upgrades.

All input and output ports are pre-installed with SC/APC connectors, with connector insertion loss already included in the overall loss specification.

On-site installation requires no fusion splicing equipment-only SC flanges or adapters are needed to complete end-to-end connections. This design significantly shortens project deployment cycles, reduces skill requirements for construction personnel, and minimizes failure risks caused by unstable on-site splicing quality.

The 1.5-meter pigtail length has been validated through practical engineering, meeting cabinet routing requirements while avoiding space waste and loss accumulation from excessive length.

Leveraging the inherent advantages of PLC planar waveguide technology, this product achieves highly uniform splitting across 32 output ports. Throughout the entire operating wavelength range, the optical power difference between any two output ports is ≤1.5dB, far superior to fused biconical taper splitters.

This uniformity ensures that each terminal in multi-user scenarios receives essentially consistent optical power, preventing degraded user experience or insufficient link budget due to uneven splitting, particularly suitable for user-dense residential communities and commercial buildings.
