RF/Fiber Optic WDM Transceiver AC231W
Features · 2000 MHz Bandwidth · 1.3 or 1.5 µm DFB Low Noise Laser · High Dynamic Range · WDM for bidirectional transmission · Internal Optical Isolator · Monitoring and Alarm Capability · Laser Disable · Singlemode Fiber Description The AC 231W is a linear, low noise RF fiber optic transceiver designed for fiber optic wireless systems and broadband RF applications. The system is composed of a fully integrated transceiver module designed for wide temperature performance and transmission over a single fiber. The transmitter utilizes a high performance, linear, optically isolated DFB laser operating at 1.3 or 1.5 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. Specifications (Tc = 25OC) Parameter Wavelength, peak Bandwidth ( WB option) Frequency Flatness, 800­2000 MHz (WA,WB) Input and Output VSWR RF Isolation, In-band (1) Spur Free Dynamic Range (2) RF Link Gain (2) Noise Figure (2) WM option WA option WB option 103 ­2 The receiver utilizes a broadband, low distortion InGaAs PIN diode photodetector. The RF interface is via a 50 SMA connector and the optical connector is a low reflection FC/APC connector. The frequency response is from 50 to 2000 MHz. The unit requires a single 12 volt DC supply. Options exist for IP3, NF and bandwidth. A laser and received optical power monitor and alarm is provided. An internal WDM permits bidirectional transmission over one fiber. The AC 231W-1.3 transmits at 1.3um and the AC 231W-1.5 transmits at 1.5 um wavelength. Three channel systems are also available.
