Table 3-10 Swrd Electrical Specifications - Alcatel-Lucent 7330 Product Information Manual

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, when the video return channel is configured for the SWRD Ethernet port,
power is available.

use IEEE 802.3-compliant materials.
The environmental specifications of the SWRD are as follows
•
operating temperature range is –40°F to 140°F (-40°C to 60°C) and to the
equivalent of 105.8°F (41°C) with solar loading
•
operating relative humidity is 5% to 95%, non-condensing
•
operating altitude range is 200 ft (61 m) below mean sea level to 13 000 ft (3962
m) above mean sea level
•
operating temperature can vary by 3°F (16.6°C) per minute, to the maximum and
minimum ranges
The physical specifications of the SWRD are as follows
•
housing dimensions: 6.78 in. wide by 1.29 in. deep by 5.77 in. high (17.45 cm by
3.38 cm by 14.66 cm)
•
weight: 1.5 lb (0.68 kg)
3.9 RSSI specifications
Received signal strength indication (RSSI) is a measurement of radio signal strength
at the receiver. Use of the RSSI metric is governed by the IEEE 802.11 standard,
which does not define any relationship between RSSI value and power level in mW
or dBm. RSSI measurements are specified without units and range in value from 0
to 255 with the highest value being referred to as RSSI Max. Defining RSSI values
or power levels is the responsibility of the vendor.
According to the Alcatel-Lucent implementation of RSSI for ONTs, the RSSI value
is expressed in power levels of dBm and is the measurement of the received optical
signal level at 1490 nm in dBM. The RSSI range is -65.536 to +65.534. The absolute
accuracy of the optical signal reading is +/-3.0 dB. Take this possible variation in
measured signals into account when reading the metric values.
