SFP Optical Transceivers for 2.7Gb/s 180km

DWDM Applications

IGP-28111J

The Bookham IGP-28111J optical transceiver is a high

performance, cost effective module for serial optical data

communication applications up to 4.25Gb/s. The IGP-28111J

Features:

• 180km (3600ps/nm) transmission compliant to V-16.2

is designed to accept DWDM SONET/SDH (with or without

FEC) and Ethernet protocol traffic for 180km links.

• DWDM SFP MSA compatible

• +4dBm optical power output

• 100GHz channel spacing

The product is designed for single mode fibre and

operate at ITU wavelengths across the C- and L-band.

The modules aid system hardware engineers in implementing

low-cost DWDM solutions, which are protocol transparent. The

“hot pluggable” feature built into every module reduces

manufacturing and inventory costs allowing 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.

• C- and L-Band coverage

• Up to 4.25Gb/s data rate

• High accuracy thermal wavelength management

• Extended APD-based receiver sensitivity

• Typically 880mW power consumption

• Single +3.3V power supply

• 0°C to +70°C operating case temperature range

• Hot Pluggable

The IGP-28111J uses the established Bookham Buried

Heterostructure Directly Modulated Laser (BH DML) packaged

in a compact cooled TOSA. The transmitter has full IEC60825-

1:2001 and CDRH Class I laser safety certification.

The Bookham IGP-28111J module has been extensively tested

utilizing industry standard single mode fibres in order to

ensure compatibility with SONET-grade enterprise, access and

metro systems. Additionally, all Bookham products are UL,

CAN/CSA, FCC, IEC, and CDRH compliant.

• Duplex LC connector

• Enhanced digital diagnostics

• Low EMI

Compliance:

• CDRH & IEC Laser Safety

Data Sheet

Diagnostics specifications

A digital diagnostics interface is available on Bookham SFP

transceivers as a 2-wire serial interface and provides user

access to module identification data, customer specific data,

link type, static and dynamic monitors 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, enquire about

its compatibility with the system and also verify which

enhanced diagnostics are supported. The user can also

monitor module parameters to determine the module and link

condition and provide hardware alerts upon an alarm or

warning event.

The memory location starting at A0h (data address 0 ~ 128)

contains the Serial ID fields. This is a static data memory

location for details such as vendor information, module

identification, user specific data and a check code for verifying

accuracy in the data registers.

The memory location starting at A2h (data address 0 ~ 255)

contains Enhanced Diagnostics fields. The Enhanced

Diagnostics are based on the SFF-8472 specification

developed in the SFF (Small Form Factor) standards

organization with an added TX_FAULT interrupt feature that

provides a hardware alert upon reaching an alarm or warning

condition on any, or all, of the diagnostics monitors. Enhanced

Diagnostics provide a real-time indication of system and

module condition, alerting the user to apparent or pending link

or module problems. This is implemented through the use of

alarm and warning registers that are updated approximately

every 60 milliseconds. Data from these registers are internally

calibrated over the specified operating ranges as described in

this data sheet. Alarm and warning thresholds are factory

preset values and are interpreted as real 16 bit data. The

optional TX_FAULT interrupt feature, if activated, pulls the

TX_FAULT pin (pin 2) high upon reaching an alarm or warning

condition on the diagnostics monitors mentioned above. The

masking feature allows any of the warning and alarm flags to

be dynamically masked by the user.

The Enhanced Digital Diagnostics provide real-time monitoring

of

receiver

input

power,

transmitter

power,

internal module temperature, laser bias current and supply

voltage parameters.

The 2-wire serial interface is defined by the GBIC (GigaBit

Interface Converter) specification and the SFP MSA

(Multi-Source Agreement) document dated September 14th,

2000. It is also compliant with the proposed DWDM SFP MSA

Document. This interface allows read-only access to two

separate memory locations starting at 1010000X (A0h)

and 101000X (A2h). Table 3 and Table 4 contain address

descriptions and register mapping information for both

memory locations.

Package and Handling Instructions

Process Plug

It is important to note that single mode optics, as with all optical devices are susceptible to contamination from air borne particles,

human body oils, and mating connector particles. Care should be taken to protect all exposed optical interfaces with process

plugs and dust covers. All Bookham IGP-2000 SFP products are supplied with a process plug. This plug protects the transceiver’s

optics during standard handling and manufacturing processes. It is recommended that the process plug remain in the transceiver

whenever an optical fibre connector is not inserted.

ESD Discharge (ESD)

Normal ESD precautions are required during the handling of this module. This transceiver is shipped in ESD protective packaging

and it should not be removed from its packaging or otherwise handled unless in an ESD protected environment utilizing standard

grounded benches, floor mats, and wrist straps.

Eye Safety

The Bookham IGP-2000 Series SFP products are Class I laser products per IEC/EN60950-1:2001 and 60825-1:2001, and are

certified per CDRH, 21 CFR 1040, Laser Safety Requirements. It is an eye safe device when operated within the limits of this

specification. Operating this product in a manner inconsistent with intended usage and specification may result in hazardous

radiation exposure. Tampering with this laser based product may warrant, under law, re-certification of the modified product as

required by the U.S. Food and Drug Administration (21 CFR 1040).
