Detailed product specifications

Functional Diagram

1 Absolute Maximum Ratings

Note: Stress in excess of the maximum absolute ratings can cause permanent damage to the transceiver.

2 General Operating Characteristics

3 Electrical Characteristics (TOP(C) = 0 to 70 ℃, TOP(I) =-40 to 80 ℃,VCC = 3.13 to 3.47 V)

Notes:
1. Connected directly to TX data input pins. AC coupling from pins into laser driver IC.
2. Into 100Ω differential termination.
3. 20 – 80%. Measured with Module Compliance Test Board and OMA test pattern. Use of four 1’s and four 0’s sequence in the PRBS 9 is an acceptable alternative.
4. LOS is an open collector output. Should be pulled up with 4.7kΩ – 10kΩ on the host board. Normal operation is logic 0;
loss of signal is logic 1.

4 Optical Characteristics (TOP(C) = 0 to 70 ℃, TOP(I) =-40 to 80 ℃, VCC = 3.13 to 3.47 V)

Notes:
1. Average power figures are informative only, per IEEE 802.3ae.
2. Measured with worst ER; BER<10-12; 231 – 1 PRBS.

5 Pin Defintion And Functions

6 Transceiver Block Diagram

Note:
1.Module circuit ground is isolated from module chassis ground within the module.
2.should be pulled up with 4.7k – 10k ohms on host board to a voltage between 3.15Vand 3.6V.
3.Tx_Disable is an input contact with a 4.7 kΩ to 10 kΩ pullup to VccT inside the module.
4.Mod_ABS is connected to VeeT or VeeR in the SFP+ module. The host may pull this contact up to Vcc_Host with a resistor in the range 4.7 kΩ to10 kΩ.Mod_ABS is asserted “High” when the SFP+ module is physically absent from a host slot.

7 Serial Interface for ID and DDM

The 7213090 10G SFP+ BIDI ZR 1490/1550nm 80KM LC SMF Fiber Optic Transceiver support the 2-wire serial communication protocol as defined in the SFP+ MSA. The standard SFP+ serial ID provides access to identification information that describes the transceiver’s capabilities, standard interfaces, manufacturer, and other information. Additionally, This SFP+ transceivers provide an enhanced digital diagnostic monitoring interface, which allows real-time access to device operating parameters such as transceiver temperature, laser bias current, transmitted optical power, received optical power and transceiver supply voltage. It also defines a sophisticated system of alarm and warning flags, which alerts end-users when particular operating parameters are outside of a factory set normal range.

The 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), so the originally monitoring interface makes use of the 8 bit address(A2h), so the originally defined serial ID memory map remains unchanged. The structure of the memory map is shown in Table1.

8 Digital Diagnostic Specifications

Notes:
1.When Operating temp.=0~70 ºC,the range will be min=-5,Max=+75
2. Internally measured
3. The accuracy of the Tx bias current is 10% of the actual current from the laser driver to the laser

9 Typical Interface Circuit

10 Recommended power supply filter

Note:
Inductors with DC resistance of less than 1Ω should be used in order to maintain the required voltage at the SFP input pin with 3.3V supply voltage. When the recommended supply filtering network is used, hot plugging of the SFP transceiver module will result in an inrush current of no more than 30 mA greater than the steady state value
