Fused Biconic wavelength Division Multiplexer

Fused Biconic WDM

Lightem’s Fused Biconic wavelength Division Multiplexer (FB WDM) can effectively combine and separate single mode signals at two wavelength ranges. It is available in a variety of wavelength ranges (1310/1550, 1064/1310, 1310/1480, 980/1550 nm). Based on the proven Fused Biconic Taper (FBT) technology, these multiplexers provide broad operating wavelengths and low insertion loss. All our WDMs are available with bare fibers, 0.9mm tubes, 2mm or 3mm loose tubes with different connectors.

  • Low Insertion Loss
  • High Return Loss
  • Compact Size
