2. Route the timing input/output coaxial cables (if not already routed) between the SDR PCIx
Host card and the GPS interface device (per system design) and cut to the required length.
Allow sufficient slack for dressing and organizing cables at the SDR PCIx Host card.
Allow sufficient slack for dressing and organizing cables at the SDR PCIx Host card.
3. Terminate each cable end with the appropriate male connector following the connector
supplier’s recommendations.
4. Connect the cables to the connectors on the SDR PCIx Host card as shown in
Figure 2. Coax Connectors
5. Dress and secure cables at the SDR PCIx Host card per standard industry practice.
6. Connect the coax cables to GPS receiver as specified in instructions provided with that unit.

Optical Cabling
3.3.1
Optical Options and Requirements
Each SDR PCIx Host Card and its associated remote (radio head) unit is connected over a pair
of optical fibers. One fiber transports the forward path optical signal and the other fiber
transports the reverse path optical signal. When diversity is used a third fiber is connected to the
REV DIV port. 9/125 single-mode optical fiber is used for the optical transport connection.
With 9/125 single-mode fiber, the optical path may be up to 10 kilometers in length. Optical
