The FiberLink XA-1900-7ST 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 FiberLink XA-1900 converts an incoming time code signal into a varying current that intensity modulates the transmitting LED located in the optical connector on the unit. The modulated light is then applied to a fiber optic cable
