Broadband RF over Fiber Tranceiver

model：

This module is a low cost high performance Broadband Optical Transceiver with very wide Dynamic Range designed for RF over Fiber applications. Designed for optical RF applications. This module offers high Spurious Free Dynamic Range (SFDR) with operational frequencies from 500 KHz to 6 GHz. The standard optical connector is FC/APC for low back reflection applications and the RF interface is via a 50 Ohms SMA connector. The Receiver features a high performance InGaAs photodiode and the Transmitter is based upon a linear optically Isolated DFB Laser operating at either 1.3 or 1.5 ?m over 9/125 ?m Single Mode Fiber.Average Automatic Power Control (AAPC) is incorporated for optimal optical power stability over the full operating temperature range.
