XFP Optical Transceivers for 10km
10G Datacom and Storage Applications
IGF Series
IGF-17311J
Features:
The Bookham IGF Series optical transceiver modules are
high-performance, cost-effective modules for serial optical data
communication applications at 10Gb/s. They are designed to
provide 10Gb/s Ethernet and 10Gb/s Fiber Channel 10 km
compliant links.
The modules are designed for single mode fiber and operate at
a nominal wavelength of 1310nm. They incorporate Bookham’s
exclusive optical packaging platform.
The modules aid system hardware engineers in implementing
low-cost single mode Physical Media Dependency (PMD)
solutions that are protocol transparent. The “hot pluggable”
feature built into every module reduces manufacturing cost,
inventory costs and allows optical port upgrades at the
customer premises. Built-in remote monitoring via digital
diagnostics allows user access to static and dynamic data
as well as module condition.
The IGF-17311J uses a DFB laser packaged in conjunction with
an optical isolator. This design provides for maximum eye
opening, minimized jitter generation, and excellent back
reflection performance. The transmitter is fully EN/IEC60825-1
Class 1/Class I laser eye safety compliant.

Mechanical interface
The XFP module is a pluggable module with its foundation based on the successful SFP package configuration. It consists of a
rectangular package that is approximately 18mm wide and 78mm long. The module interface is a 30 lead connector. The module
is inserted into a metal cage assembly. As an option, a heat sink can be clipped to the cage to enhance the cooling of the module.
Figure 5. Example of clip-on heat sink
Thermal interface
One of the unique features of the XFP module is that the module cage is designed with the ability to have a thermal heat sink
clipped onto the cage. Thus the equipment manufacturer that designs with the XFP can select a heat sink that is optimized for the
particular environmental conditions of vertical space above module, air flow, air flow direction and desired pressure drop.

Management Interface
Digital diagnostics is an available interface on all Bookham XFP
transceivers. A 2-wire Serial ID interface provides user access
to vendor/module identification, customer specific data, link
type, static and dynamic monitor hooks, and a check code
mechanism for verifying accuracy in the data registers. These
“static” and “dynamic” diagnostics allow users to remotely and
accurately identify modules and their vendors, make
determinations about its compatibility with the system, verify
which “Enhanced” diagnostics are supported, and monitor
module parameters to determine the module and link
condition.
The module’s “Enhanced Digital Diagnostics” features provide
real-time monitoring of receiver input power, transmitter power,
internal module temperature, laser bias current, and supply
voltage parameters.
The 2-wire serial ID interface was originally defined by the GBIC
(GigaBit Interface Converter) and SFF-8472 specifications. The
XFP MSA (Multi-Source Agreement) document further defined
the diagnostics features and introduced a new memory map of
the diagnostic information. This interface is a 2-wire interface
that allows read-only access to separate memory locations.
The memory location starting at A0h (data address 0 ~ 127)
contains the Digital Diagnostic Functions.
The normal 256 Byte I2C address space is divided into lower
and upper blocks of 128 Bytes. The lower block of 128 Bytes
is always directly available and is used for the diagnostics and
control functions that must be accessed repeatedly.
9
One exception to this is that the standard module identifier
Byte defined in the GBIC and SFP is located in Byte 0 of the
memory map (in the diagnostics space) to allow software
developed for multiple module types to have a common
branching decision point. This Byte is repeated in the Serial ID
section so that it also appears in the expected relationship to
other serial ID bits.
Multiple blocks of memories are available in the upper 128
Bytes of the address space. These are individually addressed
through a table select Byte which the user enters into a
location in the lower address space. Thus, there is a total
available address space of 128 * 256 = 32Kbytes in this upper
memory space. The upper address space tables are used for
less frequently accessed functions such as serial ID, user
writable EEPROM, reserved EEPROM and diagnostics and
control spaces for future standards definition, as well as ample
space for vendor specific functions. These are allocated as
follows:
• Table 01h: Serial ID EEPROM
• Table 02h: User writable EEPROM
The details of each memory space are found in the XFP MSA
specification Chapter 5.
