Fiber Optic RF Backbone

Lynx Broadband provides a line of fiber optic RF backbone components including high-performance fiber optic transmitters and receivers, which are typically used for building-to-building distribution in campus environments, or distribution between the main distribution frame (MDF) and intermediate distribution frame (IDF) closets in large buildings. The receivers are designed with state-of-the-art GaN (Gallium Nitride) technology that provides extremely high signal quality.

1310 nm single-mode fiber is used for these applications. Cable losses are only .6 dBm per mile and the signals are impervious to electromagnetic interference and lightning strikes.

To insure proper system design and installation, Lynx will provide a complete system design (at no charge). This includes a detailed design drawing showing the equipment layout and the recommended signal strength at each transition point.

Fiber Optic Transmitters

Four high quality fiber transmitters are available, with outputs of 3, 8, 10, and 12 dBm.  They have sufficient power to distribute RF to up to ten locations.

A free system design from Lynx Broadband is recommended before selecting the appropriate transmitter for a given application.

Transmitter Options

• Fiber TX with 3 dBm out.  Rated for one or two receivers.
• Fiber TX with 8 dBm out.  Rated for three or four receivers.
• Fiber TX with 10 dBm out.  Rated for five or six receivers.
• Fiber TX with 12 dBm out.  Rated for seven to ten receivers.

The information above assumes distances under .8 miles (4000 feet), and installation of an appropriate optical splitter after the transmitter.  A free system design from Lynx Broadband is recommended before selecting the appropriate transmitter for a given application.

The transmitters are equipped with an LCD display that provides a variety of diagnostic information including the operating temperature, current flow to the laser diode, and power from the laser diode. They also include a high quality pre-distorter that minimizes distortions in the incoming and outgoing signals.

Fiber Optic Receivers

Fiber receivers are available in wallmount and rackmount versions as well as forward path only and bi-directional. The forward path receivers have color coded LED indicators showing the approximate signal strength of the incoming signal, as shown below. If an optical power meter (OPM) is not available, these indicators are very helpful in optimizing system performance. The ideal signal level coming into the receiver is 0 dBm.
