EDM 01-17 DAG 4.5G2/G4/GF Card User Guide
Port
Connectors
The DAG 4.5G2/GF card has 2 x Small Form Factor (SFP) socket
connectors. The DAG 4.5G4 card has 4 x SFP socket connectors. Each
connector consists of an optical fiber or copper transmitter and receiver.
The upper connector of each pair is used for the transmit signal and the
bottom connector of each pair is used for the received signal.
Note: The DAG 4.5G.2/G4 supports both optical and copper
transceivers. The DAG 4.5GF supports optical transceivers only.
The DAG 4.5G4 has an 8-pin socket located below the optical port
connectors on the card bracket. The DAG 4.5G2/GF has a 4-pin socket in the
same location. These sockets are available for connection to an external time
synchronization source.
Caution: Never connect anything other than a PPS input to the time
synchronization sockets.

Transceivers
Overview
The DAG 4.5G2/G4 card supports industry standard Small Form-factor
Pluggable (SFP) optical transceivers.
Note: The DAG 4.5GF transceivers are not pluggable
The transceivers consists of two parts:
•
Mechanical chassis attached to the circuit board
•
Transceiver unit which may be inserted into the chassis
Note: You must select the correct transceiver type to match the optical
parameters of the network to which you want to connect. Configuring
the card with the wrong transceiver type may damage the card.
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

Setting Power
The optical power range depends on the particular SFP module that is fitted
to the DAG card. However Endace recommends you use the 1000baseSX
850nm short range modules which are shipped with the card.
Optical power is measured in dBm. This is 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.
The DAG 4.5 card optics power module specification is shown below:
