PLZT Optical Switching Systems

The PLZT optical switching systems are ready to switch optical signals at nano-second speed with PC control capability. The PLZT optical switching subsystem is equipped with a MZ type PLZT optical switch with single mode fiber ports, a high-speed driver, and FPGA controller with D-Sub ports in a single 19 inch case. This switch does not require an external multi-channel pulse generator. Available port counts include 1x1, 1x2, 1x8, 1x16, 2x2, and 4x4.

With efficient electro-optic properties and high refractive index, EpiPhotonics' unique PLZT waveguide technology enables a new generation of efficient optical switch systems with potent advantages such as;
  • Ultra-fast switching (10 ns)
  • Low driving voltage (5V~10V)
  • Low insertion loss
  • Low polarization dependence
  • Low power consumption
  • Miniaturization
In addition, the PLZT products are very reliable and environmentally stable. The crystal structure of our PLZT materials and the fact that our optical switches have absolutely no moving parts guarantee high reliability and stability.
  • High reliability (high-power laser admissive)
  • Environmentally stable


EpiPhotonics' high-speed and low-power consumption products provide the key differentiators for many optical switching applications such as;
  • Optical packet switching (OPS)
  • Optical burst switching (OBS)
  • On-demand ROADM
  • On-demand crossconnects
  • Switched optical access networks
  • Optical interconnections (data center networks, server backplanes)
  • High-speed protections
  • Switched delay lines (phased array antennas, optical buffering)
