Transmitter Section

The transmitter converts 10Gbit/s serial PECL or CML electrical data into serial optical data compliant with the
10GBASE-LR standard. An open collector compatible Transmit Disable (Tx_Dis) is provided. A logic “1,” or no
connection on this pin will disable the laser from transmitting. A logic “0” on this pin provides normal operation.
The transmitter has an internal automatic power control loop (APC) to ensure constant optical power output across
supply voltage and temperature variations. An open collector compatible Transmit Fault (Tx_Fault) is provided.
TX_Fault is a module output contact that when high, indicates that the module transmitter has detected a fault
condition related to laser operation or safety. The TX_Fault output contact is an open drain/collector and shall be
pulled up to the Vcc_Host in the host with a resistor in the range 4.7-10 kΩ. TX_Disable is a module input contact.
When TX_Disable is asserted high or left open, the SFP+ module transmitter output shall be turned off. This
contact shall be pulled up to VccT with a 4.7 kΩ to 10 kΩ resistor

Receiver Section

The receiver converts 10Gbit/s serial optical data into serial PECL/CML electrical data. An open collector
compatible Loss of Signal is provided. Rx_LOS when high indicates an optical signal level below that specified in
the relevant standard. The Rx_LOS contact is an open drain/collector output and shall be pulled up to Vcc_Host
in the host with a resistor in the range 4.7-10 kΩ, or with an active termination. Power supply filtering is
recommended for both the transmitter and receiver. The Rx_LOS signal is intended as a preliminary indication to
the system in which the SFP+ is installed that the received signal strength is below the specified range. Such an
indication typically points to non-installed cables, broken cables, or a disabled, failing or a powered off transmitter
at the far end of the cable.
