DAC 155o, 2x155o and 2x155e Configuration
For a 9500 MXC Node, this section describes tributary configuration for:
• DAC 155o and 2x155o. Provides STM1/OC3 single mode SC optical
interfaces; one for the 155o, two for the 2x155o. The receive-level range is -31
dBm (max sensitivity) to -7 dBm (max input power). The transmit-level range
is Min -15 dBm to Max -8 dBm.
• DAC 2x155e. Provides two G.703 electrical STM1, 75 ohm unbalanced, BNC
interfaces.
For 9500 MXC IDU 155o this section describes configuration of its STM1/OC3
single mode SC optical interface. The receive-level range is -31 dBm (max
sensitivity) to -7 dBm (max input power). The transmit-level range is
Min -15 dBm to Max -8 dBm (as for DAC 155o).
DAC 1x155o, 2x155o and 2x155e Screens
Figure 7-9 shows a typical DAC 2x155o Plug-ins screen.
• The 1x155o screen is identical except for a single trib line.
• The 2x155e screen is identical.
Before connecting fiber-optic cables, check optical levels at both ends to ensure
compatibility. An under or over-driven optical receiver will cause bit errors. If
necessary use a fiber-optic power meter to measure levels.
Attenuator cables are available as optional accessories.
