Output Signal Definitions
Levels for the signals described in this section are listed in Receive Signal Interface on page 8 and Control
Electrical Interface on page 9.
Rx_DAT
The incoming optical signal is converted and repowered as a differential PECL serial data stream. The
Receive Signal Interface table on page 8 gives the voltage levels and timing characteristics for the Rx_DAT
signals.
Rx_SD
The Receive Signal Detect line is high (a logical one) when the incoming modulated light intensity is sufficient
for reliable operation. This is the state for normal operation. The line is low (a logical zero) when the incoming
modulated light intensity is below that required to guarantee the correct operation of the link. Normally, this
condition only occurs when either the link is unplugged or the companion transceiver is turned off. This signal
is normally used by the system for diagnostic purposes.
This signal has a push-pull output driver.
Tx_Fault (Only available on 2 X 6)
Upon sensing an improper power level in the laser driver, the SFF sets this signal high and turns off the laser.
The Tx_Fault signal can be reset with the Tx_Disable line.
The laser is turned off within 100
μ
s as shown in the Transmitter Fault Detection timing diagram below.
This signal has an open drain TTL driver. A pull up resistor is required on the host side of the SFF connector.
The recommended value for this resistor is 10k
.
