The OZ514 Series is an Ultra Broadband RFoF (UB‐RFoF), with individual Tx and Rx modules providing cost-effective high-performance transport over RF over Fiber Optics (RFoF) applications. These Links with bandwidths of up to 4GHz have High Spurious Free Dynamic Range (SFDR) supporting applications such as CBRS and, as well as, other wireless standards within the 4GHz band. The Our UB‐RFoF series of our Linear Analog Links are designed as compact RF plugin Modules for Single Mode Fiber operation. They are designed to be compact with built in RF shield to support low EMI/RF interference for Single Mode Fiber applications. The standard optical connector is SC/APC (FC/APC is also available) for low back reflection applications. The Receiver features a high performance InGas photodiode and the Transmitter is based upon a linear isolated DFB Laser at wavelengths of 1310nm, 1550nm or CWDM grade. Average Automatic PowerControl (AAPC) is incorporated for optimal optical power stability over the full temperature range. The RF interface is via a 50 Ohms SMA connector. Alarm and Monitoring functions are available through a 10-pin connector.
