RF/Fiber Optic Transceiver AC231-2.5

Features · 2500 MHz Bandwidth · 1.3 µm Low Noise DFB Laser · High Dynamic Range · Optical Stabilization · Monitoring and Alarm Capability · Singlemode Fiber

Description The AC 231-2.5 is a linear, low noise RF fiber optic transceiver designed for fiber optic wireless antenna remoting or repeater applications and other RF systems. The system is composed of a fully integrated transceiver module. The transmitter utilizes a high performance, linear isolated DFB laser operating at 1.3 µm over 9/125 um singlemode fiber. For optimal stability, the laser incorporates average optical power feedback which monitors and actively adjusts the laser for constant power output over temperature and lifetime. The receiver utilizes a highspeed, low distortion InGaAs PIN diode photodetector. Specifications (Tc = 25OC) Parameter Wavelength, peak Bandwidth Frequency Response, 50 to 2500 MHz Input and Output VSWR Spur Free Dynamic Range (1) RF Link Gain (2) Output Noise Floor Input 3rd Order Intercept Notes: (1) SFDR specified with optical loss budget of 2 dB. (2) Link Gain specified with 1 meter fiber.

The RF interface is via a 50 SMA connector and the optical connector is a low reflection FC/APC connector. The unit requires a single 12 volt DC supply with no external settings necessary. A laser and received optical power monitor and alarm is provided. The AC 231-2.5 transceiver integrates the transmitter and receiver section into one package. Individual TX and RX are available. Other packaging options including internal WDM for bidirectional single fiber transmission are available.
