Internal Calibration

Measurements stored in data address byte 96~ 105 are calibrated over transceiver operating temperature andsupply voltage and are interpreted as defined in SFF-8472 Rev9.5. Alarm and warning threshold values should beinterpreted in the same manner as real time 16 bit data.

External Calibration

Measurements are raw A/D values and must be converted to real world units using calibration constants stored inEEPROM locations 56 – 95 at 2 wire serial bus address A2h. Calibration is valid over transceiver operatingtemperature and voltage.

Alarm and warning threshold values should be interpreted in the same manner as real time 16 bit data.

After calibration per the equations given below for each variable as described in SFF-8472 Rev9.5, the results areconsistent with the accuracy and resolution goals for internally calibrated devices.

Internally measured transceiver temperature.Temperature,T(oC), is given by

T = TSLOPE * TAD + TOFFSET

WhereTADis 16-bit signed 2's complement A/D value at bytes 96-97,TSLOPEis unsigned fixed-point value

at bytes 84-85 andTOFFSETis signed 2's complement value with LSB equal to 1/256 deg-C at bytes 86-87.

The result,T, is 16-bit signed 2's complement value with LSB equal to 1/256 OC, yielding a total range of

-128 OC to +128 OC.

Internally measured supply voltage:Voltage,V(µV), is given by

V = VSLOPE * VAD + VOFFSET

WhereVADis 16-bit unsigned A/D value at bytes 98-99,VSLOPEis unsigned fixed-point value at bytes 88-89andVOFFSETis signed 2's complement value with LSB equal to 100 µV at bytes 90-91. The result,V, is16-bit unsigned value with LSB equal to 100 µV, yielding a total range of 0-6.55V.

Measured transmitter laser bias current:Current (µA),I, is given by

I = ISLOPE* IAD + IOFFSET

WhereIADis 16-bit unsigned A/D value at bytes 100-101,ISLOPEis unsigned fixed-point value at bytes

76-77 andIOFFSETis signed 2's complement value with LSB equal to 2 µA at bytes 78-79. The result,I, is

16-bit unsigned value with LSB equal to 2 µA, yielding a total range of 0-131mA.

Measured coupled TX optical output power:Power,TX_P(µW), is given by

TX_P = TX_PSLOPE * TX_PAD + TX_POFFSET

WhereTX_PADis 16-bit unsigned A/D value at bytes 102-103,TX_PSLOPEis unsigned fixed-point value at

bytes 80-81 andTX_POFFSETis signed 2's complement value with LSB equal to 0.1 µW at bytes 82-83. The

result,TX_P, is 16-bit unsigned value with LSB equal to 0.1 µW, yielding a total range of 0-6.5mW.

Measured received optical power:Power,RX_P(µW), is given by

RX_P = R4 * RX_PAD4+ R3 * RX_PAD3+ R2 * RX_PAD2+ R1 * RX_PAD + R0

Where RAD is 16-bit unsigned A/D value at bytes 104-105 and R4, R3, R2, R1 and R0 are single precision

floating-point values at bytes 56-75. The maximum value for R4, R3, R2, R1 and R0 is 1e8. The result,

RX_P, is 16-bit unsigned value with LSB equal to 0.1 µW, yielding a total range of 0-6.5mW.

Function Description

The transceiver provides high-speed Bi-directional serial optical link forXGPON10G downstream and 2.5G upstream application up to20km.

The burst-mode transmitter part has a 1270 nmDFBlaser. It featuresac-coupled differential data inputs. TX_BRST is a LVTTL input for TX shut down control. Logic “1” disables the LD driver.

The 1577nm continuous-mode receiver part has a high performance photo detector. The preamplifier (TIA) andlimiting amplifieramplify the incoming optical signal into the stable range and convert the signal to differential ac-coupled outputs.RX_LOSis LVTTL output, which logic “1” indicates the input power is lower than the threshold, logic “0” indicates the input power is above the threshold.
