COMMUNICATIONS COMPONENTS

Key Features

?High kink-free powers to 400 mW

?Reduced TEC power consumption,compatible with legacy temperature control

?Low-profile 14-PIN butterfly planar package ?Fiber Bragg grating stabilization ?Wavelength selection available

?Integrated thermoelectric cooler,thermistor,and monitor diode ?High dynamic range

The JDSU 2745 series of 980 nm pump modules uses a planar construction with chip on subcarrier.The `semicooled' 45°C laser diode operation provides for a significant reduction in TEC and overall power consumption.The high-power JDSU laser chip is hermetically sealed in a low-profile,14-pin butterfly package,fitted with a thermistor,thermoelectric cooler,and monitor diode.The module meets the stringent requirements of the telecommunications industry,including T elcordia GR-468-CORE for hermetic 980 nm pump modules.

The 2745 series pump module,which uses fiber Bragg grating stabilization to lock the emission wavelength,provides a noise-free,narrowband spectrum,even under changes in temperature,drive current,and optical feedback.Wavelength selection is available for applications requiring the highest performance in spectrum control with the highest powers available.

Note:Absolute maximum ratings are the maximum stresses that may be applied to the pump module for short periods of time without causing damage.Stresses in excess of the absolute maximum ratings can permanently damage the device.Exposure to absolute maximum ratings for extended periods,or exposure to more than one absolute maximum rating simultaneously may adversely affect device reliability.

1.The Tracking Error is defined as the normalized change of output power relative to the operating power over case temperature range 0°C to 75°C,at constant back face monitor current corresponding

to the operating power at 25°C.

2.The Tracking Ratio is a measure of the front-to-back tracking when the output power is varied.On a plot of optical power versus back-face photocurrent,a straight line is drawn between the minimum

power (20 mW) and the operating power P op points.The tracking ratio is defined as the ratio between measured optical power (shown as data points on the plot) to the value derived from the straight line.

21 CFR 1040.10 Compliance

Because of the small size of these devices,the output power and laser emission indicator label shown below is attached to the individual shipping container.All labels are illustrated here to comply with 21 CFR 1040.10 as applicable under the Radiations Control for Health and Safety Act of1968.

Safety and Operating Considerations

The laser light emitted from this diode laser is invisible and may be harmful to the human eye.Avoid looking directly into the fiber when the device is in operation.

CAUTION:THE USE OF OPTICAL INSTRUMENTS WITH THIS PRODUCT INCREASES EYE HAZARD.

Operating the diode laser outside of its maximum ratings may cause device failure or a safety hazard.Power supplies used with this component cannot exceed maximum peak optical power.

CW diode lasers may be damaged by excessive drive current or switching transients.When using power supplies,the diode laser should be connected with the main power on and the output voltage at zero.The current should be increased slowly while monitoring the diode laser output power and the drive current.Careful attention to heatsinking and proper mounting of this device is required to ensure specified performance over its operating life.T o maximize thermal transfer to the heatsink,the heatsink mounting surface must be flat to within .001”,and the mounting screws must be torqued down to 1.5 in.-lb.

ESD PROTECTION — ESD is the primary cause of unexpected diode laser failure.Take extreme precaution to prevent ESD. Use wrist straps,grounded work surfaces,and rigorous antistatic techniques when handling diode lasers.
