PLZT Optical Switch Modules and Subsystems. The PLZT optical switch modules and PLZT optical switch subsystems are
powerful tool to switch optical signal at nano-second speed with low polarization dependence. The PLZT optical switch subsystem is equipped with a MZ type PLZT switch, single mode fiber ports, and a TTL controllable highspeed driver.
Advantages
Thanks to its efficient electro-optic properties and high refractive index.
EpiPhotonics' unique PLZT waveguide technology enables a new generation
of efficient optical switch subsystems with potent advantages such as;
 High-speed switching (< 5~10 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
Applications
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)
