DEV 7233 & DEV 7333 Optribution Top L-Band RF over Fiber Link

DEV 7233 & DEV 7333 Optribution Top L-Band RF over Fiber Link

The DEV 7233 and DEV 7333 Optribution Top L-Band RF over Fiber Link provide high-performance analog transmission of extended L-band signals over long-distance single-mode fiber. The link operates from 850 to 2450 MHz and supports a recommended optical budget of up to 20 dB, making it suitable for teleports, satellite ground stations, remote antenna sites and CWDM fiber networks.

The DEV 7233 transmitter features adjustable gain and continuous optical modulation index optimization, enabling reliable handling of aggregate RF input levels from -70 to +10 dBm. Integrated LNB power supplies switchable 13/18 VDC and 0/22 kHz control with current monitoring.

The DEV 7333 receiver provides adjustable gain and slope compensation with high output linearity. Both hot-swappable modules include RF sensing, front-panel status LEDs, local push-button controls and SMA monitoring ports. Multiple optical connector and CWDM wavelength options support application-specific fiber infrastructure.
