AC Coupled SFP Module EEPROM Information and Management The SFP modules implement the 2-wire serial communication protocol as defined in the SFP -8472. The serial ID information of the SFP modules and Digital Diagnostic Monitor parameters can be accessed through the I2C interface at address A0h and A2h. The memory is mapped in Table 1. Detailed ID information (A0h) is listed in Table 2. And the DDM specification at address A2h. For more details of the memory map and byte definitions, please refer to the SFF-8472, “Digital Diagnostic Monitoring Interface for Optical Transceivers”. The DDM parameters have been internally calibrated.   Table 1. Digital Diagnostic Memory Map (Specific Data Field Descriptions) Table 2 - EEPROM Serial ID Memory Contents (A0h) Data Address Length (Byte) Name of Length Description and Contents Base ID Fields 0 1 Identifier Type of Serial transceiver (03h=SFP) 1 1 Reserved Extended identifier of type serial transceiver (04h) 2 1 Connector Code of optical connector type (07=LC) 3-10 8 Transceiver 11 1 Encoding NRZ(03h) 12 1 BR, Nominal Nominal baud rate, unit of 100Mbps 13-14 2 Reserved (0000h) 15 1 Length(9um) Link length supported for 9/125um fiber, units of 100m 16 1 Length(50um) Link length supported for 50/125um fiber, units of 10m 17 1 Length(62.5um) Link length supported for 62.5/125um fiber, units of 10m 18 1 Length(Copper) Link length supported for copper, units of meters 19 1 Reserved 20-35 16 Vendor Name SFP vendor name: JHA 36 1 Reserved 37-39 3 Vendor OUI SFP transceiver vendor OUI ID 40-55 16 Vendor PN Part Number: “JHA320CD” (ASCII) 56-59 4 Vendor rev Revision level for part number 60-62 3 Reserved 63 1 CCID Least significant byte of sum of data in address 0-62 Extended ID Fields 64-65 2 Option Indicates which optical SFP signals are implemented(001Ah = LOS, TX_FAULT, TX_DISABLE all supported) 66 1 BR, max Upper bit rate margin, units of % 67 1 BR, min Lower bit rate margin, units of % 68-83 16 Vendor SN Serial number (ASCII) 84-91 8 Date code JHA’s Manufacturing date code 92-94 3 Reserved 95 1 CCEX Check code for the extended ID Fields (addresses 64 to 94) Vendor Specific ID Fields 96-127 32 Readable JHA specific date, read only 128-255 128 Reserved Reserved for SFF-8079   Digital Diagnostic Monitor Characteristics Data Address Parameter Accuracy Unit 96-97 Transceiver Internal Temperature ±3.0 °C 98-99 VCC3 Internal Supply Voltage ±3.0 % 100-101 Laser Bias Current ±10 % 102-103 Tx Output Power ±3.0 dB 104-105 Rx Input Power ±3.0 dB   Regulatory Compliance   The JHA520CD-5 complies with international Electromagnetic Compatibility (EMC) and international safety requirements and standards (see details in Table following).
