Optical isolators
Click here or scroll down to view the full Optical isolator product listing
An optical isolator allows the transmission of light in only one direction. i.e. this optical component will prevent unwanted light from returning back into an optical cavity. To relate to its function in Electrical terms, would be a similar to that of a diode, allowing current to only flow in only one direction. The main component of optical isolators is usually a Faraday rotator.
Optosun manufacture a complete range of narrowband, broadband and ultra-wideband fuse-based optical Isolator couplers and pump combiners offering high isolation and low insertion loss. There are various options, including Free space, Dual and single stage, Single mode or Multi mode, S,C and L band, Polarisation sensitive and independent. Our products are produced with either thin-film-filter- (TFF-) or fused bionical tapered- (FBT-) technology.
Typical applications include: Fiber Optic Lasers, Tunable Lasers, Optical Transmitters, WDMs, EDFA, Instrument Testing and others.
Our Isolators operate from the spectral ranges of 865 nm to beyond 2000 nm but we also have a full engineering facility to produce customer specials as required.
We also offer high power Isolators rated up to 20W, plus a range of Optical Hybrid isolators combined with Tap options, WDM and GFF gain-flattening filters.
Custom - Non Standard Optical Isolators
We can also produce bespoke isolators, which may require features such as smaller or larger aperture sizes, custom wavelength range, polarisation, custom package size etc. Also we can offer singlemode and multimode isolators that can be tuned to work optimally in different operating temperatures. Please contact us to discuss your special Optical Isolator requirements.

WDM - CWDM - DWDM - OADM Multiplexing products
Click here to view the full WDM product listing
WDM works by simultaneously combining and transmitting multiple signals at different wavelengths but within the same fiber.
This enables effective management of bandwidth and also helps to expand the capacity of existing Fibre Optic systems, components and modules.
WDM is protocol and bit-rate independent. These networks can transmit data in IP, ATM, SONET/SDH, and Ethernet.
They can handle bit rates between 100 Mb/s and 40 Gb/s. Therefore, WDM type networks can carry different types of traffic at different speeds over an optical channel.
The Optosun Technology production lines have now been increased to cover the full product range of WDM devices, module, and module integration, including thin-film filter (TFF) base WDM products, and also fused fiber base coupler WDM products.
