Telecom

A variety of optical thin film filters are used throughout modern telecommunication fiber-optic networks. Iridian designs and manufactures a wide range of standard and custom tailored thin film filters suitable for rigorous telecom applications.

Iridian's advanced deposition technology is used to fabricate optical thin films that are dense and robust. The resulting filters have physical and optical properties that are ideally suited for even the most demanding applications.

Standard & Custom Telecommunications Filters

	Band Pass Filters Bandpass filters (BPF) are used to transmit one or more bands of wavelengths while blocking (or reflecting) adjacent wavelengths over extended ranges.
	Beamsplitters and Tap Couplers Beamsplitter filters are typically used to split one beam into two beams through transmittance and reflectance.
	CWDM Product Line Coarse wavelength division multiplexing (CWDM) filters multiplex and de-multiplex wavelength signals in metropolitan networks, access networks, enterprise networks and cable networks.
	Edge Pass Filters - Telecom EPFs are used in telecommunications applications where wavelength band separation or optical add-drop multiplexing (OADM) is required.
	FTTx Filters Tri-band optical filters are used for wave division multiplexing (WDM) in fiber to the home or business (FTTx) applications.
	Gain Flattening Filters Gain Flattening Filter (GFFs), also known as gain equalizing filters, are used to flatten or smooth out unequal signal intensities over a specified wavelength range.
	Linear Transmittance Filters Linear transmittance filters are used for wavelength identification applications, employing a transmittance that changes linearly over a specified wavelength range.
	Multiple Band Pass Filters Iridian offers a full range of multiple band pass filters in the visible and near IR wavelength ranging from 400nm-2500nm.
	Single Cavity Etalon Filters Single Cavity Etalon Filters are narrow bandpass filters (typically with FWHM < 0.5 nm) that are well-suited for wavelength-locking applications
	Solid Etalon Filters Solid Etalon Filters have a well-defined periodically spaced frequency grid and are typically used for wavelength locking or dispersion compensation (all-pass filters).
	Telecom Band Pass Filters Bandpass filters (BPF) are used to transmit one or more bands of wavelengths while blocking (or reflecting) adjacent wavelengths over extended ranges.
