Tunable Edge Filters
-
Tunable edge filter is a customized product. It usually belongs to 2-port optical tunable filter product platform. Instead of using narrow bandpass filter in the 2-port tunable optical filter, the tunable edge filter utilizes a low-pass or long-pass interference filter. By changing the incident angle of the light beam, the cut-off wavelength will be tuned. Standard Tunable edge filters support C-band or L-band wavelength range.

2-Port Optical Tunable Filter
-
Optoplex's Tunable Optical Filter, also known as Optical Tunable Filter or Tunable Bandpass Filter, is an integrated module, consisting of micro optics and electronics. When receiving a stream of optical signals of a plurality of wavelengths from the Input-Port (IN), the 2-port tunable optical filter directs a selected channel to the Output-Port (OUT). The selected channel can be varied (tuned) within the operating wavelength (frequency) range by a remote command sent through the built-in control PCB and firmware.

Anechoic Chamber Filters
-
RF leakage through Ethernet and USB cables can destroy even the best RF enclosures and chambers. The need for filtering in the ever congested RF environment requires special filters that can pass USB 2.0 and 10/100/1000 Mbps Ethernet signals and filter out unwanted higher frequencies such as cellular and WiFi. The Adaura Technologies USB/Gigabit Filters provide one GigE and one USB 2.0 pass-through connections while filtering out other RF up to 8GHz. It has a small form factor to allow easy installation. It is a most cost effective solution for a clean chamber set up. In a typical chamber, WiFi signals are reduced to <-100dBm with this filter installed.
