Data Sheet
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.

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 = VBF. (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 VNM

Data Sheet
Instructions for use
- GND / GND-TEC:
Ground reference pin and package potential. All voltages are referred to this node.
- VCC:
General positive power supply of the module. Typical value : + 5.0 V.
- VTEC:
TEC (Thermo-Electrical Cooler) supply. Typical value + 3.3 V.
- DATAP / DATAN (Data inputs):
NRZ data input, internally AC coupled with 50 ohm internal termination. A logical "1" of D is related to a light on state on the optical fibre.
Data line is retimed at the input of the module by the input clock signal when the function is selected.
In case of operation in the transparent mode of the transmitter no internal signal regeneration function is provided.
Input impedance: 50 V typical.
- CLKP / CLKN (Clock inputs):
Clock inputs internally AC coupled with 50 ohm internal termination. The rising edge of the clock+ signal must be central to the
steady state of the data pattern.
Input impedance: 50 V typical.
- TXDIS (TX disable input):
Under shutdown condition the output power should be low enough so that any receiver, in minimum span condition,
will generate an LPA (Loss of Power Alarm).
When TXDIS is high the TX module is disabled (no optical output power).
When TXDIS is low (or open) the TX module is in the operating condition.
TTL compatible input. Input includes pull down resistance of 100 kV typical.
- CSEL (Selection of data input clocking mode - future enhanced feature):
When CSEL is high the module operates in the non clocked mode, this is the supported operational mode for the MT10EW.
TLL compatible input. Pull down resistance of 100 kV typically.
- LDA (Laser degradation alarm):
Digital alarm indicating that the laser is degraded. LDA activation ISOL +/-20%, hysteresis +/-10mA
The active level is a low level.
The alarm shall not be activated in shutdown condition.
TTL compatible output.
- LTDA (Laser temperature degraded alarm):
Alarm indicating when the laser temperature exceeds the recommended operational limits. LTDA activation TSOL +/-2°C,
hysteresis +/-0.5°C.
The active level is a high level.
TTL compatible output.
- PWR_MON (Back Facet Monitor):
Laser back facet monitor derived voltage. This monitor produces a scaled varying analogue voltage that tracks the transmitted
optical output power.
Output impedance < 10 V typically.
- NUC:
No user connection, this pin can be tied to any static potential within the operating supply range.
- I2C & GUI interface (future enhanced feature):
The module includes an I2C interface bus which enables the user to interogate the module alarms and monitors using a host controller.
- Wavelength drift alarm (future enhanced feature):
An option exist to provide a wavelength drift alarm using the LTDA alarm port, which activates when the laser wavelength
exceeds +/-30pm of the SOL (start of life) value.
