24 PIN 10Gb/s Long Reach DWDM Serial

Transmitter Module

MT10EW

The Bookham MT10EW 10Gb/s LR Transmitter Module is a

1550nm, low power, small footprint 24-pin module enabling

high port density. It is designed to support a SONET / SDH or

10GE interface between the photonics layer and the electrical

layer for applications with reach requirements of 80km or

more. The Transmitter allows convenient direct connection to

system card electrical MUX ASICs, using un-clocked mode of

data transfer.

The transmitter has been designed for Dense Wavelength

Division Multiplexed (DWDM) operation for applications up

to 11.1GB/s.

Low power dissipation coupled with small footprint

significantly simplifies high speed card design. This results in

significant savings in card space and development time, and

greatly improved time to market.

The module provides wavelengths on the 50GHz ITU-T grid in

the C band. It is also available for non-WDM applications that

use a single wavelength. Multi functional hardware alarms and

monitors are also available for systems card and network

management.

The MT10EW LR 24 pin Transmitter Module can be used in

existing OC192 and OC192c ports as well as emerging IEEE

802.3ae 10 Gigabit Ethernet WAN / LAN ports.

The MT10EW LR Transmitter Module is optimised for optical

link spans of 80km+ (based on GR-253, ITU G.691 and IEEE

802/3ae system architectures). Reaches in excess of 80km

may be achieved in proprietary networks.

The compact size, low power Transmitter Module is 24 pin

connectorised for convenient surface mount assembly. The

module comprises a hermetically packaged laser device and

Bookham’s InP Mach-Zehnder modulator Technology with

optical isolation and wavelength stabilisation. This ensures

that the optical source remains within optical power and

wavelength limits over variations in temperature and over life.

A microprocessor coupled with internal circuitry and a

Thermo-Electric Cooler (TEC) controls the operation of the

module and ensures the correct laser temperature to achieve

constant wavelength.

Features:

• Incorporates Bookham InP MZ Technology enabling

superior systems performance.

• +3.5 to +7dBm start of life, over temperature optical

output power window

• Internal microcontroller for TX wavelength, power &

opticalperformance control

• Multi functional hardware alarms and monitors for

systems card and network management

• 2 x 12 way 0.1" x 1.5” pitch electrical interface

• 73.4 x 50.0 x 12.7mm MSA compliant outline

• 24pin MSA compliant

• +3.3V / +5V external power supply rails

• Typical power dissipation 3W

• IEC/EN 60825 Class 1M laser safety classification

• Case operating temperature range -5 to +75C

• RoHS 5/6 compliant

Applications:

• 10Gbps fixed wavelength, Long Reach DWDM serial

transmitter module suitable for 80km+

reach applications

• Suitable for use in 1550nm Long Reach applications

based on Telcordia GR-253, ITU-T G.691and IEEE

802.3ae system architectures

Data Sheet

Notes:

[1] Two complementary signals of equal amplitude on each input.

[2] Referred to data level 20% or 80%, see diagram below for definitions.

[3] When not connected the TXDIS, CSEL inputs are considered in a low state, (internal pull-down resistor).

Clocked mode, CSEL=low is presently unsupported for the MT10EW.

[4] Time measured from rising edge of shutdown signal until optical output has turned off (<-40dBm).

[5] Time measured from falling edge of shutdown signal until optical output power is over 0dBm and emitted wavelength is at

nominal value +/- 200 pm. The unit is assumed to be powered on for at least 30s.

[6] Time measured from falling edge of shutdown signal until optical output power is within the specified range and

wavelength within +/-30pm.

The unit is assumed to be powered on for at least 30 seconds.

[7] Time measured from enabling laser until optical output power is within the specified range and wavelength within +/-120pm.

Module powered for 5 seconds minimum prior to enabling laser.

For any initial case temperature within the specified operational range and with TXDIS = off.

[8] Back facet monitor voltage is measured from pin 2 to GND and normalized at the beginning of life relative to the initial optical

output power (Tcase = 25°C, nominal power supply). The relationship is approximately linear, as represented by the equation:

Back-facet voltage = V

. (measured optical output power/initial BOL optical output power), power measured in mW.

For example, a 50% variation of this voltage means a 50% drift of the optical output power.

Nominal

Characteristics

[9] Total relative variation of the mean modulated optical fibre output power over the operating case temperature and supply

voltage ranges for a constant back facet voltage.

[10] A sinewave is superposed to the DC supply voltage. The device must still meet the optical and electrical specifications when

the magnitude of the sinewave measured at any VCC pin (pin 13 and 24) is up to the specified value V
