    Product Descriptions

     The XFP Bidi is compliant with the IEEE803.3ae 10Gbase-Bx. and transmission distance up to 20km on SMF .The transceiver module comprises a transmitter with a 1270 or 1330nm DFB laser transmitter, an integrated 1330 or 1270nm detector preamplifier(IDP) mounted in an optical header and a limiting post-amplifier IC. Transmitter and receiver are separate within a wide temperature range of 0℃ to +70℃ for commercial temperature, -40 to 80 °C for industrial temperature, and offers optimum heat dissipation and excellent electromagnetic shielding for 10 GbE systems application.

    Notes:

    1. Module circuit ground is isolated from module chassis ground within the module.

    2. Open collector; should be pulled up with 4.7k – 10k ohms on host board to a voltage between 3.15Vand 3.6V.

    3. Reference Clock input is not required.

     

    Management Interface  The SFP incorporates an XFP-compliant, two-wire management interface which is used for serial ID, digital diagnostics, and certain control functions. It is modeled on the SFF-8472 specification modified to accommodate a single two-wire interface address. In addition to the basic I2C read/write functionality, the modules support packet error checking that, when enabled, allows the host system to confirm the validity of any read data. Details of the protocol and interface are explicitly described in the MSA. Please refer to the MSA for design reference.The digital diagnostic memory map specific data field defines as following
