Description

Product Information

The Wolon 1x4 Mini PLC (Planar Lightwave Circuit) splitter is a high-reliability optical power management component designed for space-constrained integration within ODFs, splice closures, and fiber distribution boxes. Utilizing a silica glass waveguide circuit and high-precision V-groove technology, this blockless splitter delivers uniform optical splitting with minimal insertion loss across the full 1260nm to 1650nm wavelength spectrum.

Compared to traditional FBT couplers, our PLC technology ensures superior thermal stability and splitting uniformity, making it the standard choice for mission-critical GPON and EPON deployments.

Key Advantages

Ultra-Compact Footprint: Housed in a precision stainless steel tube, this "blockless" design is ideal for high-density applications where traditional ABS box splitters are too bulky.

Premium G.657A1 Fiber: Built with bend-insensitive fiber as standard, ensuring negligible signal attenuation even in the tightest routing paths inside small termination boxes.

Broadband Performance: Operates reliably across the entire O, E, S, C, and L bands, fully supporting next-generation XG-PON and XGS-PON upgrades.

Low PDL (Polarization Dependent Loss): Minimal sensitivity to polarization states ensures consistent signal delivery regardless of input fiber orientation.

Carrier-Grade Durability: 100% factory tested for insertion loss, uniformity, and return loss. Every unit is designed for a 20-year service life in varying outdoor OSP environments.
