3 SDR PCIx HOST CARD CABLING
3.1 Optical and Electrical Connections
Optical and electrical connections with the remote unit and GPS are supported by four optical
and two electrical ports. The electrical interface to the GPS is through coaxial cable connections
using two type SubMiniature version A (SMA) female connectors. Single-mode fiber provides
the optical connection between the SDR PCIx Host Card and Remote Units. The forward and
reverse ports provide the optical communication channel in a non-diversity system. The REV
DIV port provides receive optics for a diversity system. Each optical port uses a small form
factor LC-type optical transceiver. Modular optical transceivers are field replaceable and
available separately.
3.2 Coax Cabling
3.2.1 Coaxial Cable Requirements
SDR
PCIx Host card is equipped with SMA -type female 50-Ohm connectors for connecting the
timing input/output signals from the GPS unit. High performance, flexible, low loss 50-ohm
coaxial communications cable (RG316 or equivalent) should be used for all coaxial connections.
RF coaxial cable connectors are N-type (female) 50 Ohms input/output impedance.
Caution: To prevent damage to the server or expansion boards, power down the server and
remove all AC power cords before removing or installing the PCI riser cage.
