General This document specifies the characteristics of the Small Form Factor Pluggable optical transceiver (Type:HTR6516) with LC duplex receptacle for 1.25Gbit/s Gigabit Ethernet and 1.0625Gbit/s Fibre Channel. Maximum transmission distance is 10km at the data rate of 1.25Gbit/s and 1.0625Gbit/s. This transceiver apply single mode optical fiber - 9/125. 2. Function This transceiver is powered from a single +3.3V power supply and operated at a data rate of 1.25Gbit/s or 1.0625Gbit/s(NRZ). Optical output power is held constant by automatic power control over the specified operating temperature and voltage ranges. The optical output is disabled by a TTL logic level input for that purpose. Tx Fault is provided to indicate the degradation of the laser diode. Loss Of Signal (LOS) output is provided to indicate the loss of an incoming optical signal. Tx Fault and LOS are open collector type outputs. The type of this transceiver is identified by Module Definition function using a built-in EEPROM with I2C interface. As enhanced functions for SFP, internally measured transceiver temperature, internally measured supply voltage, laser bias current, laser optical output power and received optical power can be monitored by reading a built-in memory with I2C interface for that purpose. The interface pins for the monitor function are common with the Module Definition function. Dimensions and pin assignment fully comply with MSA (Multi Source Agreement) for SFP (Small Form Factor Pluggable) optical transceiver. 3. Explanation of Part Number

Unless otherwise stated, minimum and maximum values are specified over the operating ambient temperature, and humidity ranges, DC power supply voltage range, from beginning to end of life, using 27-1 pseudo random bit stream with a 50% duty factor. The logic sense for the DATA input is such that a logic "1"(High) corresponds to the maximum level of an amplitude modulated light source (Light on), while a logic "0"(Low) corresponds to a minimum level of an amplitude modulated light source (Light off).

The measured values located at bytes 96-105 (in the 2 wire address 0xA2) are raw A/D values (16-bit integers) of transceiver temperature, supply voltage, laser bias current, laser optical output power and received power. All the measured values are "externally calibrated" over specified temperature and supply voltage, and then it is necessary to convert raw A/D values to real world units using the external calibration constants located at bytes 56-91 (0xA2) by the manner as shown in Table 6.2. Table 6.2 Measured Values / 2 wire address 1010001X (0xA2) Name Description Temp MSB Internally measured transceiver temperature, TAD (16-bit signed 2's complement integer). Actual temperature, T, is given by, T=T1*T AD+T0, Temp LSB where T1 and T0 are calibration data at bytes 84-87. The result is 16-bit signed 2's complement value with LSB equal to 1/256 deg -C (see Table 6.3a), yielding a total range of -128 to +128 deg-C. Accuracy of result is better than +/-3 deg -C. Vcc MSB Internally measured supply voltage, VAD (16-bit unsigned integer). Actual voltage, V, is given by, V=V1*VAD+ V0, where V and V are calibration 1 0 Vcc LSB data at bytes 88-91. The result is 16-bit unsigned value with LSB equal to 100 V (see Table 6.3b), yielding a total range of 0 to 6.55 V. Accuracy of result is better than +/-50 mV. Note that transmitter supply voltage measured since VccT and VccR are isolated. Laser Bias MSB Measured Laser bias current, BAD (16-bit unsigned integer). Actual current, B, is given by, B=B1*BAD+B0, where B and B are calibration Laser Bias LSB 1 0 data at bytes 76-79. The result is 16-bit unsigned value with LSB equal to 2 A (see Table 6.3b), yielding a total range of 0 to 131 mA. Accuracy of result is better than +/-8 mA. Tx Power MSB Measured Tx power, P (16-bit unsigned integer). Actual power, P, is AD given by, P=P1*P AD+P0, where P and P0 are calibration data at bytes Tx Power LSB 1 82-85. The result is 16-bit unsigned value with LSB equal to 0.1 W (see Table 6.3b), yielding a total range of 0 to 6.55 mW. Accuracy is better than +/-3dBm. Rx Power MSB Measured Rx power, RAD (16-bit unsigned integer). Actual power, R, is given by Rx Power LSB R = R4*RAD4 + R3*RAD3 + R2*RAD2 + R1*RAD + R0, where R4, R3, R2, R1 and R0 are calibration data at bytes 56-75. The result is 16-bit unsigned value with LSB equal to 0.1 W (see Table 6.3b), yielding a total range of 0 to 6.55 mW. Accuracy is better than +/-3dBm over the specified optical input power.

The formats of values shown in Table 6.2 are interpreted below. The result of temperature, T, and the calibration intercepts, T0, V0, B0, and P0, are 16-bit signed 2's complement numbers with corresponding LSB (e.g. laser bias, B , has 2 A LSB) as shown in Table 6.3a. The result of Vcc, V, 0 laser bias, B, Tx power, P, and Rx power, R are 16-bit unsigned numbers with corresponding LSB (e.g. laser bias, B, has 2 A LSB) as shown in Table 6.3b. The calibration slopes, T1, V1, B1, and P1, are unsigned fixed-point numbers as shown in Table 6.3c. The calibration coefficients, R4, R3, R2, R1, and R0, are IEEE-754 single precision floating-point numbers as shown in Table 6.3d.

This transceiver is implemented two optional status bits, "Logic States" at byte 110 (0xA2) and "A/D Updated" at byte 111 (0xA2) as shown in Table 6.4. "A/D updated" status bits allows the user to verify if an update from the analog -digital conversion has occurred to the measured values, temperature, Vcc, laser bias, Tx power and Rx power. The user writes the byte to 0x00. Once a conversion is complete for a given value, its bit will change to '1'.

Alarm and warning flags at bytes 112-119 (0xA2) are defined as follows, (1) Alarm flags indicate conditions likely to result (or have resulted) in link failure and cause for immediate action, (2) Warning flags indicate conditions outside the guaranteed operating specification of transceiver but not necessarily causes of immediate link failures.
