DEV 7232 & DEV 7332 Advanced L-Band RF over Fiber Link

DEV 7232 & DEV 7332 Advanced L-Band RF over Fiber Link

The DEV 7232 and DEV 7332 Advanced L-Band RF over Fiber Link provide high-linearity analog transmission of extended L-band signals over single-mode fiber. Operating from 850 to 2450 MHz, the link is designed for direct signal conversion at large satellite antennas, RF distribution in uplink stations and other applications requiring high input-signal handling.

The DEV 7232 transmitter incorporates a limiter function and integrated LNB power with current monitoring. The DEV 7332 receiver provides 0-5 dB adjustable gain for balancing RF output levels across different optical paths. The latest datasheet specifies an optical budget of up to 20 dB under stated operating conditions.

Both hot-swappable modules provide RF sensing, front-panel status LEDs, local push-button controls and dedicated SMA monitoring ports. Standard 1550 nm and optional 1310 nm transmitter wavelengths are available, along with SC/APC, FC/APC and E2000/HRL optical connectors.
