Data Sheet
4W 940nm
Uncooled Multimode Laser Diode Module
MU4-940-04
The Bookham MU4-940 multimode laser diode module has
been designed to provide the high power and reliability required
for pumping next generation high power amplifiers for CaTV
and FTTx. The pump module includes a multimode laser diode
chip with E2 front mirror passivation that prevents Catastrophic
Optical Damage (COD) to the laser diode facet even at very high
power levels. The coupling process allows for high output
powers that are very stable with both time and temperature.
Features:
• High output power 4W
• 0.22NA 105µm core multimode fiber pigtail
• Hermetically sealed package
• Floating anode/cathode
• High reliability
• Excellent solderability
• Standard wavelength at 940nm
• Low power dissipation
• RoHS compliant
Applications:
• High power EDFA for CaTV and FTTx
• Er/Yb co-doped double clad pumping

Operating Characteristics:
Conditions unless otherwise stated:
• Parameters at 25°C heat sink temperature and use of a thermal interface material rated for a thermal impedance
of less than 1.3cm2 .K/W (0.2in2 .K/W)
