DEV 728x & 738x Desktop RF over Fiber Links, 47-2600 MHz

DEV 728x & 738x Desktop RF over Fiber Links, 47-2600 MHz

The DEV 728x and DEV 738x Desktop Optribution Series provides compact, standalone analog RF over fiber transmission for satellite, broadcast and CATV applications. The plug-and-play modules combine fixed gain, high linearity and simple installation for most intra-facility and interfacility optical links.

The DEV 7285 transmitter and DEV 7385 receiver cover 700-2600 MHz, including the complete L-band range. They are recommended for links with optical losses up to 5 dB, while the datasheet specifies an optical budget up to 6 dB under stated conditions. The DEV 7285 also provides switchable LNB power.

The DEV 7287 and DEV 7387 cover 47-1006 MHz for CATV, VHF, UHF and wireless-audio signal transport. Both link families include RF monitoring, optical-status LEDs, overtemperature protection and universal external power supplies.
