− Do not crush the cable or allow it to kink. Doing so may cause damage that can alter the transmission characteristics of
the cable. The cable may have to be replaced.
• Use an optical power meter and light source for checking the fiber optic cables
• Make sure the environment is clean while connecting/splicing fiber optic cables
• All fiber optic connectors should be cleaned prior to connecting to the system
• Fiber connector protective caps should be installed on all non-terminated fibers and removed just before they are
terminated.
• Pay special attention while connecting the LC APC connectors – ensure that you hear a “click”, indicating a secure
connection
• Never look directly into the end of a fiber that may be carrying laser light. Laser light can be invisible and can damage your
eyes.
3.3 Antenna Specifications and Guidelines
Determine the antenna installation configuration, according to the transmission and coverage requirements and the installation
site conditions.
3.3.1 Authorized Antennas and Required Specifications
• External antennas - no limitation on any vendor of available external antennas with respect to the following requirements:
− Omni Directional or directional
− Supported frequency range: wideband antennas supporting a range of 700 MHz to 2600 MHz
− Gain: up to 12.5 dBi
− Impedance: 50 Ohm
• Couplers – Use N-Male to N-Female broadband coupler separately ordered from Corning (P/N AK-1COUPLER-NM-NF)
or the equivalent:
− Broadband frequency: 300 – 3000 MHz
− -20 dB coupling (SMA coupling port)
− Maximum VSWR/return loss:12 dB
− Maximum insertion loss (dB): 0.2
• Number of antennas that can be connected (with cables/splitters) – it is not recommended to connect more than one
antenna per connector since 1:1 connectivity is reduced with each split.
• Types of couplers/splitters – depends on number of splits (not recommended)
