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. 1 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 • Multi bit rate performance 9.953 Gb/s (OC192, 10GE WAN), 10.3125 Gb/s (10 GE LAN), 10.664 10.709 11.1 Gb/s (FEC), Data Sheet Characteristics Unless otherwise stated the following parameters and performances are required over the full range of operating conditions defined below, from beginning to end of life.

Clocked mode, CSEL=low is presently unsupported for the MT10EW.  Time measured from rising edge of shutdown signal until optical output has turned off (<-40dBm).  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.  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.  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.  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.

Note:  Only non-clocked mode is presently supported with the MT10EW module. 6 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. 7 Data Sheet Outline Drawing 8 Data Sheet Ordering Information (Connector) J28 = SC/PC J33 = FC/PC J57 = LC J59 = MU #### = Last four digits of wavelength value E.g. for lp = 1545.32 nm #### = 4532 e.g. MT10EW4532AAA-J28 is a 1545.32 nm 24 pin module with an SC connector.
