DIGITAL DIAGNOSTIC FUNCTIONS
The Avanex XFP module provides a management interface as described in the XFP standard (MSA Rev 4.5). There are
3 control input signals, 3 status output signals, and a 2-wire serial interface. The signals are described in section 2.4 of the
XFP standard. The control signals allow the module to be placed in a low-power state, to be reset, to enable/disable the
serial interface, and to turn-off the transmitter. The status signals indicate loss of received signal, detection of an invalid
condition, and the presence of additional status information via the serial interface.
The serial interface provides access to the more detailed identification and diagnostic monitoring information. It provides
access to a 256-byte register space. This interface runs at up to 400 kHz (with occasional clock stretching not exceeding
500µs), and the module supports a packet error checking protocol to verify transfer integrity. Full details are described in
chapter 4 of the XFP standard.
The register space is divided into upper and lower 128-byte spaces, as described in chapter 5 of the standard. The lower
128-bytes provides access to the more frequently accessed information, including readout of optical signal and laser
levels, alarm and warning flags, and read/write of control and status signals. The upper 128-bytes contain one of a
number of pages of information. The desired page is selected by writing a byte in the lower 128-half. Page 1 contains
extended module identification information, and page 2 provides a space of 128-bytes of non-volatile storage for the host
system.
DATA RATE
In order to accommodate the signal conditioner device used in the Avanex XFP module, the host system can either
- Forward no information. In this case, the XFP will find the datarate and lock on the incoming data stream through an
internal algorithm
-
Inform the XFP module of the data rate. The data rate is written into the upper 4 bits [7-4] of Byte 01h. The value to
be entered is given by:
Byte 01h [bits 7-4] = INT(Data rate[Gbps) – 9.5 ) /0.2))
Table below gives Byte 01h [bits 7-4] depending on the data rate used:

THERMAL INTERFACE
The XFP module cage is designed to accommodate a clip-on thermal heat sink, as shown below, to enhance the
cooling of the module. Thus the equipment manufacturer can select a heat sink that is optimized for the particular
environmental conditions of space-above-module, air flow rate & direction. For an example reference of the heat sink,
see Tyco, ref. 1542706-2.
