Wavelength selection:Note: Maximum Transmission Distance is 43.50miles (70km) for input wavelength 1570nm, 1590nm, 1610nm

 Test pattern:

• Measured with conformance test signal for PRBS 2³¹ -1 and BER<10^-12 with data rate 10.3125Gb/s, Optical source with worst ER, Wavelength between 1470nm and 1610nm:

PRBS31 test pattern represents a pseudorandom binary sequence with a repetition period of 2³¹ -1. The sequence is defined in IEEE STD 802.3.ae

BER<10^-12   test represents bit error rate testing provides a measurable and useful indication of the performance of the system

Optical source with worst ER (extended Reach)

NRZ – non-return-to-zero

• Receiver Sensitivity is measured using operation temperature range, without air flow
• 20 – 80 % Measured with Module Compliance Test Board and OMA test pattern.

Digital Diagnostics Functions:

• GAOTek GAO-SFPPCW -101 series transceivers support the 2-wire serial communication protocol as defined in the SFP MSA.
• Additionally, GAOTek SFP+ Transceivers provide a unique enhanced digital diagnostic monitoring interface which allows real-time access to device operating parameters such as transmitter optical power, receiver optical power, transceiver temperature, transceiver supply voltage and laser bias current. It defines an alarm system and warning flags, which alerts the end users when particular operating parameters are outside of a factory set normal range.
• Standard SFP+ Serial id provides access to identification information that describes the transceiver’s capabilities, standard interfaces, manufacturer and other information.
• SFP+ MSA defines a 256-byte memory map in EEPROM that is accessible over a 2 wire serial interface at the 8 bit address 1010000X (A0h).
• The operating and diagnostics information is monitored and reported by a Digital Diagnostics Transceiver Controller (DDTC) inside the transceiver, which is accessed through a 2-wire serial interface. The memories are organized as a series of 8-bit data words that can be addressed individually or sequentially

Electrical characteristics:

Notes:

1. Loss of Signal is LVTTL. Logic 0 indicates normal operation; logic 1 indicates no signal detected.

Optical Characteristics:

Notes:

1. Launched power (avg.) is power coupled into a single mode fiber with master connector. (Before of Life).
2. λc refer to wavelength selection

PIN Descriptions:

Notes:

1. Circuit ground is internally isolated from ground.
2. T_Fault is an LVTTL output.
   • High output indicates a transmitter fault caused by either the TX bias current or the TX output power or the laser temperature exceeding the preset alarm thresholds.
   • Low output indicates normal operation. In the low state, output is pulled to <0.8V
3. Laser output disabled when it is open or T_Dis > 2.0V, enabled on T_Dis < 0.8V.
4. Should be pulled up with 4.7kΩ to 10kΩ on host board to a typical voltage 3.3V.
5. MOD_ABS pulls the line low to indicate the module is plugged in.
6. Loss of signal is open collector output.

• It should be pulled up with 4.7 kΩ to 10 kΩ on host board to a typical 3.3V voltage
• Logic 0 indicates normal operation.
• Logic 1 indicates loss of signal.
