Tactical Solution: Portable & Harsh Environment Ready

The OFW 7500 / IFL; L-Band Fiber Optic Transceiver Subsystem provides “Best of Breed” optical long-haul transmission of RF signals in the frequency range of 950 MHz to 2250 MHz. The Subsystem can support the transmission of High Density L Band SATCOM traffic over distances of up to 50 km using Mil Tactical Harsh Environment singlemode interconnections.

The OFW 7500 / IFL utilizes an optical conversion process that is adaptable and transparent to the User’s data modulation rate and format. That is, the OFW-7500/IFL is specifically optimized to be integrated with all modern Software Defined Radio (SDR) waveforms. The Subsystem offers many performance advantages including an Ultra-High Spur Free Dynamic Range, 10 MHz Frequency Reference Transport, Embedded Fault & Alarm Status Monitoring over Ethernet, and Harsh Environmental Temperature Range.

In addition, the OFW 7500 / IFL supports a list optional features that enhance SATCOM terminal operation: Uplink / 10 MHz RF Frequency Diplexed Transport, Downlink LNB powering, RF Link Gain Control, Optical Dynamic Range > 10 dBo, and Extended RF Frequency Range up to 7 GHz.

The OFW 7500 / IFL can be packaged in various styles of form factors including: 1RU x 19” rack chassis, 4RU x 19” high-density plug-in card chassis, Harsh Environment / Outdoor Enclosures, and compact flange mount modules.
