Fiber-Optic Transmission
-
Fiber optic transmission systems all use data links that work similar to the diagram shown above. Each fiber link consists of a transmitter on one end of a fiber and a receiver on the other end. Most systems operate by transmitting in one direction on one fiber and in the reverse direction on another fiber for full duplex operation. It's possible to transmit both directions on one fiber but it requires couplers to do so and fiber is less expensive than couplers. A FTTH passive optical network (PON) is one of the only systems using bidirectional transmission over a single fiber because its network architecture is based around couplers already.

Avionics Data Bus Tester
Distributed CORVUS
-
Distributed CORVUS works in conjunction with CORVUS-300 to isolate bus anomalies and fault resolution. The Transmit unit, C-9235-TX, sends 1553 like data pattern through a bus stub and coupler to the Receive unit, C-9235-RX, on another stub. This will measure insertion loss, possible bit errors and correct polarity. The Receive unit can also be used to give a digital scope representation of the active data bus showing signal quality and peak to peak amplitude.

Lange Couplers
-
The Lange Coupler is a four-port interdigitated structure originally developed by Dr. Julius Lange in 1969. They are a common RF/microwave circuit. The coupling is derived from closely spaced transmission lines, such as microstrip lines. With the introduction of Ion Beam Milling, SemiGen’s ability to consistently produce Lange Couplers with lines and spaces as small as 10 microns and controlled to tolerances of +/- 1 micron is a direct result of our anisotropic ion beam etching process.

Dual (Bi) Directional Couplers
-
Pasternack dual directional coupler (also known as bi-directional coupler) series are passive devices that couple part of the transmission power in a transmission line. Our dual directional coupler components provide the bandwidth, high directivity and higher power that designers need for their most demanding applications. RF dual directional couplers often use two transmission lines set close together so that energy passing through one is coupled to the other. Many Pasternack bi-directional coupler items are RoHS and REACH compliant. Couplers that are dual directional from Pasternack are available with SC, SMA and Type N connectors. This dual/bi directional series is offered in 10dB, 20dB, 30dB, 40dB and 50dB coupling values. Power ratings for our dual directional couplers range from 10 Watts to 10 Watts. Frequency ratings for our bi-directional couplers range from 1 GHz to 8 GHz. Like the other over 40,000 RF, microwave and millimeter wave components from Pasternack, our dual (bi) directional coupler series is in-stock. Not only our these couplers in stock, they also will ship the same-day as they are purchased.
