DESCRIPTION 

As part of the Avanex XFP MSA transceiver family, the PowerPort 2040 TRX 

or 2140 TRX provides convenient and flexible optical interfaces for SONET / 

SDH, 10 GbE and 10 Gb/s Fibre Channel systems operating with or without 

FEC. It meets or exceeds the applicable ITU-T G.691, ITU-T G.709, Telcordia 

GR-253 and XFP MSA standards. 

The transmitter is based on a cooled ILM laser operating at 1.5µm. The receiver 

is a PIN-Preamp detector. 

APPLICATIONS 

Used in transmission systems for high-speed, long-reach applications, the 

PowerPort 2040 TRX or 2140 TRX transceiver operates at Multi Protocol, 

Multi-rate from 9.9 to 11.3Gb/s. All Avanex XFP MSA transceivers are suitable 

for DWDM and TDM line systems, Add/ Drop Multiplexers and digital crossconnects 

as well as ATM or IP switches and routers. These modules ensure 

ease of use and offer new flexibility for designers of 10 Gb/s optical links.

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. 

In order to accommodate the signal conditioner device used in our XFP module, the host system shall 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:

OUTLINE DRAWING 

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.
