Filter Devices (AFR)

Amplified Spontaneous Emission Filter (ASE)

The ASE Filter series are designated to pass the specified wavelength windows and block the unwanted amplified spontaneous emission noise in EDFAs and DWDM systems. It is a micro-optics device based on environmentally stable Thin Film technology. The components are characterised with low insertion loss at pass channel, good isolation for blocking wavelengths and high power handling.

Bandpass Filter

The band pass filter is a micro-optics device based on environmentally stable Thin Film Filters technology. It is used to block out unwanted noise signals in EDFAs and DWDM systems. The components are characterised with high isolation, low insertion loss, high return loss, excellent environmental stability and high power handling capability.

C and L Band WDM

The C & L Band Filter Wavelength Division Multiplexer is a micro-optics device based on environmentally stable Thin Film Filters technology. It is used to combine or separate C band wavelength signals and L band wavelength signals in DWDM systems. The components are characterised with wide passband, low insertion loss, high return loss excellent environmental stability and high power handling capability.

C Band Red/Blue WDM

The C Band Red/Blue Filter Wavelength Division Multiplexer is a micro-optics device based on environmentally stable Thin Film Filters technology. It is used to separate or combine Red band wavelength signals and Blue band wavelength signals in C band range in DWDM systems. The components are characterised with wide passband, low insertion loss, high return loss, excellent environmental stability and high power handling capability.

Coarse WDM (CWDM)

The Coarse Wavelength Division Multiplexer series are designed and manufactured to Telcordia standard. The devices use environmentally stable Thin Film Filters and advanced packaging technology to achieve wide passband, low insertion loss, high channel isolation and excellent environmental stability. They can be used individually to perform single channel add or drop function or can be cascaded into sequence for multi-channel applications in CWDM systems.

Coarse WDM Module (4/8 Channel)

The CWDM Module is expanding the bandwidth of Metro/Access Networks. The 4-channel and 8-channel CWDM modules are based on Coarse Wavelength Division Multiplexer devices. They can act as MUX/DEMUX with 20nm channel spacing. It has low insertion loss, low PDL, high isolation and good thermal stability.

Dense WDM (DWDM)

The Dense Wavelength Division Multiplexer series are designed and manufactured to Telcordia standard and ITU standard. The devices use environmentally stable Thin Film Filters and advanced packaging technology to achieve wide passband, low insertion loss, high channel isolation and excellent environmental stability. They can be used individually to perform single channel add or drop function or can be cascaded into sequence for multi-channel applications in DWDM systems.

Dense WDM Module (4/8/16 channel)

The multi-channel Dense Wavelength Division Multiplexer Modules are based on thin film DWDM devices by cascading individual channels into sequence. Channel numbers can be as high as 40 (16) for 100 (200) GHz systems in C band or in L band. They are featured with wide passband, low insertion loss, high channel isolation and high environmental stability. They can be used in Dense WDM systems to perform multiplexing or demultiplexing functions.

Filter WDM

The Filter Wavelength Division Multiplexer series are based on environmentally stable Thin Film Filters technology. The devices combine or separate light at different wavelength in a wide wavelength range. They offer very low insertion loss, low polarisation dependence, high isolation and excellent environmental stability. High power handling capability can be achieved through unique pigtail processing and high quality AR coating. These components have been extensively used in EDFAs, Raman amplifiers, WDM networks and fibre-optics instrumentation.
