The FiberLink XA-1900-C7S IRIG Fiber Optic Transmitter is designed to convert wide band IRIG analog signals into modulated light for transmission over fiber optic cables. The transmitter employs linear, intensity modulation and is suitable for use with most optical fibers. The XA-1900 employs a single ended, unbalanced input which is compatible with all IRIG input formats. There is only one operating control on the XA-1900 series. This is an input attenuator, designed to allow input signals larger than the normal 1 volt RMS level to be accommodated. The XA-1903 is a 10 channel optical output version of the XA-1900 and is designed for IRIG signal distribution applications.
The RA-1900 IRIG Fiber Optic Receiver is the companion receiver for the XA-1900 and XA-1903. It converts the modulated light from a fiber optic cable back into an exact replica of the original transmitted signal. The RA-1900 is intended for driving single ended, unbalanced loads in accordance with IRIG standards. There is only one operating control on the RA-1900 series. This is an output level control and is used to compensate for the optical attenuation of the fiber being used.
