10G SFP Board Compatible With Modules Of 11.7G Or Lower Speeds
Type of SFP+ test board and communication interface:
1. SFP+ single channel test board adopts parallel port and USB
communication interface.
2, parallel port and USB two kinds of communication interface to
simulate I2C, the rate control is 100Kbps, easy to compatible with
high and low speed I2C module.
Two, SFP+ test board function:
1. SFP+ single channel test board has the following functions:
compatible with all modules of 11.7G and below;
2, parallel port and USB two kinds of communication interface to
achieve I2C communication; Hardware control module TxDisable and hardware monitoring LOS,
TxFault status;
3, real-time temperature monitoring, real-time transmitter current
and receiving current measurement monitoring and overcurrent
protection; The output voltage range is from 2.9V to 3.8V. The output voltage
can be adjusted continuously. It is suitable for the test of the
module's pulling voltage.
4, hardware and software modules TxDisable and Power OnOFF
(switching electricity), hardware and software arbitrary
independent control.
5. The USB port supports independent power supply (when the current
of the optical module is less than 100mA).
Iii. Precautions:
1. Note that there are also devices below and behind PCBA board, so
conductive objects should not be placed on the power-on test to
avoid short circuit and burn the board.
2, the input voltage is adjusted to 5V, do not adjust the voltage
or reverse, so as not to burn the board.
3, test 10G module, support high-speed signal TX, RX electrical
signal wire needs to support 18G frequency signal cable.
