Fibre Optic Transmission – fixed gain analogue links : point2point | PPM

The point2point fibre optic links from PPM Test are fixed gain, analogue signal transmission systems designed to overcome electrical interference and signal attenuation in monitoring and distribution applications. These systems convert analogue signals using either intensity or 14-bit digital modulation, depending on the frequency range, and transmit them over fibre for high-fidelity, interference-free performance.

Benefits :

• Immune to electrical and electromagnetic interference
• Enables safe signal monitoring at high voltages
• Eliminates ground loops
• Supports very long optical paths (up to ~4 km)
• Maintains signal integrity with negligible noise degradation
• Battery-powered operation up to 36 hours

Key Features :

• Wide, flat frequency response
• Electrically shielded modules
• Available in single-mode or multimode fibre
• Compatible with AC and DC coupling
• Frequency ranges by series:
  • G series: 40 Hz – 250 MHz
  • K series: 2 kHz – 1.35 GHz
  • P series: 1 MHz – 2 GHz
  • S series: 10 MHz – 3 GHz
  • R series: DC – 2.5 MHz
  • T series: DC – 20 MHz
  • U series: DC – 40 MHz
• Optical budget monitoring via LED indicators
• SMA 50 Ω electrical connectors, FC/APC optical connectors

Typical Applications :

• EMC, EMP, HIRF, and NEMP testing
• Signal transmission in high-voltage or noisy environments
• Military and aerospace compliance testing
• Remote sensor signal acquisition
• Laboratory and field measurements

Additional Information :

The point2point systems support key standards such as MIL-STD-188-125, MIL-STD-461G, DEF STAN 59-188, and DEF STAN 59-411. With modular options and robust performance, they are ideal for demanding environments requiring reliable analogue signal transmission over fibre.
