Modern ITS communications networks demand fiber optic transmission equipment engineered and built to provide unconditional long-term reliability, stability, and performance under extremely difficult operating environments. IFS designs, builds, and tests this equipment to exceed the environmental requirements of the industry-accepted standards of NEMA TS-1, NEMA TS-2, and the Caltrans Specification for Traffic Signal Control Equipment. More IFS products have been deployed along our nations highways and light rail transit installations, than those of all of our competitors combined.

Primary IFS fiber products for the transportation market include:

Fiber Optic RS-232, RS-422, and RS-485 data Point-to-Point, Star, Linear Multi-drop, and Fault-Tolerant Self Healing Ring Transmission Equipment Products for Traffic Signalization Networks, Variable Message/Changeable Message Signs, and Electronic Toll Collection Systems.

Fiber Optic T-1/E-1 transceiver units for data transmission and telephony applications.
Environmentally Hardened single and 4-channel Ethernet fiber optic transmission equipment that transmits 10/100 Mbps data over optical fiber.

EIA/TIA RS-250C Medium-Haul and RS-250C Short-Haul Compliant Fiber Optic 2, 4, 8, & 16 and up to 32-Channel Video Multiplexers, Video with 1, 2, or 3 Full-Duplex Data Channels on a single optical fiber, and Video-Only transmission equipment for incident detection, video detection systems, toll plaza vehicle enforcement, and CCTV surveillance. These products are available using AM, FM, or recently-introduced state-of-the-art 8 and 10-bit digitally-encoded video for true broadcast quality video transmission and performance that exceeds the requirements of RS-250C Short-Haul Transmission.

Broadband configurable digital multiplexing transmission systems for the simplex or full-duplex transmission of multiple video, data, and audio signals on a single optical fiber.

Fiber optic full-duplex point-to-point and multi-drop audio frequency transceiver units for traffic signalization networks employing FSK (frequency shift keying), and for point-to-point voice-grade POTS telephony circuits for maintenance and order-wire communications applications.
