Pluggable optical transceivers
Overview
The DAG card's SFP+ optical transceivers consist of the following two parts.
• Mechanical chassis attached to the circuit board.
• Transceiver unit which may be inserted into the chassis.
You can connect the transceiver to the network via LC-style optical connectors. For further information on
pluggable optical transceivers please refer to the Endace website at http://www.endace.com.
Caution:
To prevent damage to the DAG card, ensure you select the correct
transceiver type for the optical parameters of the network to which you
want to connect.
Optical modules
The optical power range depends on the particular SFP+ module that is fitted to the DAG card. Optics
modules are supplied in either Single or Multi mode. See the following table for details.
Optical power is measured in dBm, decibels relative to 1 mW where 10 dB is equivalent to a factor of 10
in power. A negative optical power value indicates power that is less than 1 mW. The most sensitive
devices can work at power levels down as low as -30dBm or 1µW.
To confirm card port light levels, use an optical power meter.
Covering the card ports with LC-style plugs when they are not in use is highly recommended, to prevent
dust and mechanical hazards affecting optics.
