Product Description
10Gtek’s Active SFP+ Copper Cables are full-active 11.1Gbps cable assemblies. The cables are
compliant with the current SFF-8431, SFF-8432 and SFP+ MSA specifications. They fill the
expanding need for cost effective data center interconnects that cannot be served with passive
copper or expensive fiber optic solutions. 10Gtek’s unique low power silicon provides the additional
benefit of consuming 50-75% less power than optical interconnects. When systems are optimized to
operate with active copper cables, the end-to-end interconnect
consumes significantly less power and emits less EMI than passive copper based systems that
require the use of EDC hosts.
SFF-8431 requires active SFP+ cable assemblies to meet an output eye mask requirement when a
minimal eye is transmitted through the cable assembly. The input eye mask is measured by
transmitting a 10.3125 Gbps PRBS 31-1 signal into a module compliance test fixture and measuring
the eye pattern through the mated host compliance test fixture. Once the input signal is established,
the cable assemblies are measured through the module compliance test fixture. All cable assemblies
meet the bit error rate requirement of 1x10-12. This design allows for output de-emphasis and signal
amplitude to be adjusted to accomodate customer requirements.

Notes:
1.The module signal ground pins, VeeR and VeeT, shall be isolated from the module case.
2.This pin is an open collector/drain output pin and shall be pulled up with 4.7-10k to Vcc_Host on
the host board. Pull ups can be connected to multiple power supplies, however the host board
design shall ensure that no module pin has voltage exceeding module VccT/R + 0.5 V.
3.This pin is an open collector/drain input pin and shall be pulled up with 4.7-10k to VccT in the module.
4. See 2-wire Electrical Specifications .
5. This pin shall be pulled up with 4.7-10k to Vcc_Host on the host board.
Pin Description
Tx_Fault:
Tx_Fault is an output pin to indicate a fault condition of a laser.This pin is connected

Tx_Disable:
Tx_Disable is an input pin to disable the transmitter output. This pin is pulled high in
the module with a 5.11kOhm resistor.
SDA/SCL:
SDA and SCL are the data and clock pins for the I2C interaction with the
EEPROM. These pins are connected to the SDA and SCL pins of the EEPROM in
the module.
MOD_ABS:
Mod_Abs is an output pin to indicate that a module is present in the port. This pin is
connected to ground in the module.
RS0/RS1:
RS0 and RS1 are module rate select pins to determine the transmit data rate for
lasers.
Rx_LOS:
Rx_LOS is an output pin to indicate if the signal amplitude is below the receiver
threshold. This pin is connected to ground in the module.
Ground:
VeeT and VeeR are connected within the module and are used as a digital ground
for signal integrity. This digital ground does not connect to the module case or the
copper cable braid.
Power:
VccT and VccR are connected within the module and are used to power the EEPROM.
Typical voltage is 3.3 Volts and each pin has a maximum current capacity of 500 mA.
Signal:
The two high speed signal pairs, TD+/TD- and RD+/RD-, are 100 Ohm differential
impedance transmission lines with AC coupling on each RD trace.
