DEV 7261 & DEV 7361 Advanced RF over Fiber Link, 50-2000 MHz

DEV 7261 & DEV 7361 Advanced RF over Fiber Link, 50-2000 MHz

The DEV 7261 transmitter and DEV 7361 receiver form an advanced analog RF over fiber link for transporting signals from 50 to 2000 MHz. The system is suitable for satellite, broadcast, CATV, VHF/UHF and other applications requiring wideband RF transmission over single-mode fiber.

The link provides high linearity, RF sensing at both ends and monitoring ports for convenient signal verification. The DEV 7361 receiver offers adjustable gain and slope, allowing technicians to balance output levels and compensate for frequency-dependent variations between signal paths.

Standard modules use a 1550 nm DFB transmitter and SC/APC connectors. Nine wavelength choices support CWDM applications, while FC/APC and E2000/HRL optical connectors are optionally available. The hot-swappable modules fit DEV indoor and outdoor Optribution chassis.
