4x4 High Speed Optical Switch Module - NanoSpeed™

60ns rise/fall, 500kHz, low loss, bidirectional, 850nm to 1620nm, 0 to 70 °C
  • Solid-State
  • Ultra High speed
  • Ultra-high reliability
  • Low insertion loss
  • Compact



The NS Series fiber optic switch is developed for fast switching and low optical loss. This is achieved using patented electro-optical configuration featuring clean fast response without ripples. The NS fiber optic switch meet the most demanding switching requirements of continuous operations over 25 years and non-mechanical ultra-high reliability. The 4×4 configuration combines 5 2×2 NS switches mounted on a single control board with TTL signal inputs.

The NS Series switch is controlled by 5V TTL signals with a specially designed electronic driver having performance optimized for various repetition rate.

[1] Measured without connectors. For other wavelengths, please contact us.

[2] Cross talk is measured at 100kHz, which may be degraded at the higher repeat rate.

[3] It is defined as the rising or fall time between 10% and 90% of optical intensities.

[4] Defined at 1310nm/1550nm. For the shorter wavelength, the handling power may be reduced, please contact us for more information.

High power version available by incorporating fiber core enlargement (expensive).
