Applications:

  • 10GBASE-ER/EW Ethernet
  • Sonet OC-192/SDH
  • 10G Fibre channel
  • CWDM Networks

Description:

The transceiver is a very compact 10Gb/s optical transceiver module for serial optical communication applications at 10Gb/s. The SFP+-40Cxxxx converts a 10Gb/s serial electrical data stream to 10Gb/s optical output signal and a 10Gb/s optical input signal to 10Gb/s serial electrical data streams. The high speed 10Gb/s electrical interface is fully compliant with SFI specification.

The high performance 1470～1610nm CWDM EML transmitter and high sensitivity PIN receiver provide superior performance for Ethernet applications at up to 40km links.

The SFP+ Module compliants with SFF-8431, SFF-8432 and IEEE 802.3ae 10GBASE-ER. Digital diagnostics functions are available via a 2-wire serial interface, as specified in SFF-8472.

The fully SFP compliant form factor provides hot pluggability, easy optical port upgrades and low EMI emission.

  • 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)
