Optical isolators

FDK’s optical isolators come in the free space type for LD modules and thein-line type for optical fiber amplifiers, and are lined up according to shapesand characteristics.

Hybrid optical isolatorsThese composite devices incorporate optical isolators, coupler and WDMfilters, all of which are necessary components for optical fiber amplifiers.

Optical filter devicesThese composite devices incorporate ASE noise blocking filter, pump noiseblocking filter, C/L band separator filter etc., all of which are necessary devicesfor optical fiber amplifiers.

Polarization combinersFDK’s reliable polarization combiners combine two polarized pump soursesinto one to yield single high pump power.

Optical circulatorsApplying the Faraday effect of LPE film, these circulators are used for OADMand optical measuring instruments.

Optical switchesOur optical switches are much better than mechanical switches in switchingspeed, reliability and durability, due to the exclusion of any moving parts.They are suitable for switching optical paths in large-capacity opticalcommunications.

Variable optical attenuators (VOA s)Applying the Faraday effect of LPE film, the variable optical attenuators(VOA’s) features high speed response and high reliability comared withmechanical VOAs, due to the exclusion of any moving parts.

Optical couplers FDK’s ion exchanged PCL type couplers are used for variety in opticalnetworks.

FDK produces compact, high-performance and quality optical devices, using its original, Bi-substitutedgarnet thick films (LPE film) and other strictly selected materials. This catalog introduces a wide varietyof standard FDK optical devices.

These optical switches are self latching type applying the Faraday effect of LPE film. Due to the exclusion of any moving parts basednon-mechanical structures, they have attained a high reliabilityand rapid switching speed, and furthermore, using the two-holeferrule collimator, attained high isolation, low insertion loss andcompact size.

Non-mechanical (Magneto-optical)

High reliability • Latching type
