10 — ONT technical specifications
10-20 July 2008 Alcatel-Lucent 7342 ISAM FTTU ONT R04.05.06
ONT Product Information Manual Edition 01 3FE 51892 AAAA TCZZA
For LP MDU ONT applications, specific planning considerations are necessary,
including:
• use of cables other than RG-9 or RG-59
• the use of addressable taps
• the use of RF patch panels
• the use of coaxial cable for delivery of content other than RF video
• the use of RF amplifiers or repeaters
10.9 SWRD interface specifications
The SWRD meets the following compliance and safety standards:
• UL safety (UL 60950-1)
• EU safety (IEC/EN 60950-1)
• IP rating NEMA 4 (IP 56)
• EMC emissions (U.S. and Canada) FCC part 15, class B
• EMC emissions (Europe) EN 55022 and 55024
The power specifications of the SWRD are as follows:
• input voltage range 12 +-2.0 V DC
• input current of 0.25 Amps
The power can be supplied by the ONT or MDU. In the ONT PoE case, jumpers must
be configured on the EPC interface of the ONT to enable +12V power. In the MDU
case, once the video return channel is configured for the SWRD Ethernet port power
is available.
Table 10-24 lists the electrical specification for the SWRD when all ports and cabling
use IEEE 802.3 compliant materials.
