7706LT CONNECTIONS
FIBER OUTPUT:
SC/UPC, SC/APC, FC/UPC, FC/APC or ST/UPC female connector with the
optical output from the 7706LT. This connector should be connected to the
FIBER IN connector of an appropriate Evertz companion receiver model at the
destination end with a suitable fiber optic cable. The 7706LT may transmit
1310nm, CWDM or DWDM wavelengths as indicated by the part number on the
card ejector. The standard connector type is UPC. This connector type is
compatible with standard PC connectors, but for optimal return loss performance,
Evertz recommends the use of UPC fiber terminations throughout the system.
The optional APC connectors provide further enhanced return loss performance,
and when specified, should be used throughout the system.
RF IN:
Input connector for RF signals. This connector can also provide LNB power and
22 kHz tone back to the LNB.
RF OUT:
Output connector provides a buffered copy of the incoming RF signal for
monitoring purposes (signal peaking, etc.) or coaxial distribution. Although not
essential, if this connector is to remain unused, it is recommended that it be
terminated with an appropriate 75 Ohm or 50 Ohm load.
The RF input is protected to the same degree as other professional RF
devices, and will withstand a degree of ESD from handling, etc. Regardless,
proper precautions should be taken during handling, such as the use of static
bags and wrist straps. The input is not protected against lightning or other
coupling of large energy spikes. If the installation is such that the RF input
may be susceptible to spikes (e.g. direct connection to the antenna/LNB) then
appropriate supplemental surge protection should be installed (e.g.
Polyphaser).
