GENERAL DESCRIPTION
This cooled EML laser based 10Gigabit SFP+ transceiver is designed to transmit
and receive optical data over single mode fiber for link length up to 40km.
The SFP+ ER DWDM module electrical interface is compliant to SFI electrical
specifications. The transmitter input and receiver output impedance is 100 Ohms
differential. Data lines are internally AC coupled. The module provides differential
termination and reduce differential to common mode conversion for quality signal
termination and low EMI. SFI typically operates over 200 mm of improved FR4
material or up to about 150mm of standard FR4 with one connector.
The transmitter converts 10Gbit/s serial PECL or CML electrical data into serial
optical data compliant with the 10GBASE-ER standard. An open collector compatible
Transmit Disable (Tx_disable) is provided. Logic “1” or no connection on this pin
will disable the laser from transmitting. 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 that when high, indicates that the module transmitter
has detected a fault condition related to laser operation or safety. The TX_Fault
output 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 kO. 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 kO to 10 kO resistor
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 kO, 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.
