SQS solution of single-mode (SM) high-power (HP) optical connections for transmission of optical power up to 5 W.

The SQS solution is based on expanded beam technology, either through an expanding element and collimating lens (Lensed Fiber Technology), or through terminating of SM fiber by a "cap" from a coreless fiber (End Cap Technology). Both solutions ensure expansion of Mode Field Diameter (MFD) and thus reducing the power density at the plug connection. SQS HP technology is compatible with most fiber optic connectors and fiber arrays.

Available also in combination with SM fibers for short wavelengths (400 nm), polarization maintaining fibers (PM), and versions with antireflection coating (ARC) on fiber endface.

Design:

  • optical signal power up to 5 W
  • SM or PM fiber
  • many types of connector (E2000, FC, SC, …)
  • solution for fiber arrays (1D, 2D)
  • available also with antireflection coatings (ARC)

Applications:

  • EDFA amplifiers
  • DWDM technology
  • laser technology
