RF over Fiber Optic Transceiver OZ816 Series – Ultra Broadband 6 GHz DESCRIPTION The OZ816 is a high performance broadband optical transceiver with very wide Dynamic Range designed for RF over Fiber Optics applications. A pair of OZ816 transceivers will create a two way bidirectional RF to Optical and Optical to RF link. OZ816 may also be configured as individual Transmitter (Tx) or Receiver (Rx) units. It is designed in a rugged Dust‐tight Cast Metal housing in a compact package with optional WDM integrated internally for bidirectional transmission on a single strand of single mode fiber. The OZ816 RFoF Links are excellent alternatives to coaxial cable systems. They deliver significant improvements in the transport of RF signals in their native format reliably in many optical networks across broad range of frequencies. The OZ816 offers high Spurious Free Dynamic Range (SFDR) with operational frequencies from 47 MHz to 6.0 GHz, or more.
FEATURES
30 MHz to 6.0 GHz Bandwidth Approx Size: 3 x 5 x 1.25 in. Weight ¾ pound ‐40C to +75C Operating Temperature LD/PD Monitoring & Alarm High Spurious Free Dynamic Range Automatic Optical Power Control 1.3 and/or 1.5 µm Low Noise DFB Lasers Laser Conforms to Class 1 Emission Level per CDRH and IEC‐825 (EN 60825) Standards
The Standard optical connector is SC/APC (FC/APC available) for low back reflection applications. The transceiver features a high performance InGaAs photodiode and a linear Isolated DFB Laser operating at 1.3 µm (A) and 1.5µm (B) over 9/125 µm single mode fiber. Average Automatic Power Control (AAPC) is incorporated for optimal optical power stability over the full temperature range. The RF interface is via a 50 Ohm SMA connector and the RS232 and alarm and monitoring functions are available through DB9. Manual Gain control is also available.
