Product Highlights
Hirundo's Fused Biconic WDM Coupler effectively merges and separates single-mode signals from both wavelength intervals. It enables multiple wavelengths of split and synth waves (e.g. 1310/1550, 1064/1310, 1310/1480, 980/1550nm). Based on molten taper technology, these compounders offer wider working wavelengths and lower losses. And the compounder can be made into tail fiber bare fiber, 0.9mm casing, 2mm or 3mm loose casing type, with a variety of types of connectors.
