The point2point AC Coupled Link from PPM Test is a Fiber Optic Link designed for transmission of low-level RF and analog signals from 40 Hz to 3 GHz. Available in multiple series, it covers frequency ranges of 40 Hz to 250 MHz (G series), 2 kHz to 1.35 GHz (K series), 1 MHz to 2 GHz (P series), and 10 MHz to 3 GHz (S series). This fiber optic link has a gain flatness between ±0.5 dB and ±0.75 dB, noise figures of 22–26 dB, and rise times as low as 200 ps.  

The point2point AC Coupled Link supports optical path lengths up to 4 km and has a signal latency of 10 ns over 1 m fiber. It requires a DC supply of 12 V and consumes less than 250 mA (Tx module) & 150 mA (Rx module) of current. This optical fiber link is available in a EM-shielded casing with SMA female connectors along with single mode FC/APC narrow key optical connectors. It complies with key standards including MIL-STD-188-125, MIL-STD-461G, DEF STAN 59-188, and DEF STAN 59-411 and is ideal for EMC measurements, HPM experiments or distributed timing applications.
