The DBC 3:97 Splitter is built using advanced Fused Biconical Taper technology, ensuring high stability and low polarization-dependent loss (PDL). Its primary function is to act as a directional coupler in long-distance fiber runs or ISP trunk lines.
By preserving 97% of the optical power for the main trunk, this splitter minimizes the "link budget" hit, allowing the signal to travel further before requiring amplification or regeneration. The 3% tap port is perfectly suited for:High-Power Tap-Offs: Providing just enough signal for an ONT/ONU located near the main trunk line.Network Surveillance: Connecting to an Optical Power Meter (OPM) or OTDR for live line monitoring without disrupting service.Daisy-Chaining: Essential for ISP layouts where multiple splitters are connected in a series along a single fiber strand.
