PowerSource 1915 LMM
TM
10 Gb/s Digital Electro-Absorption Laser Module - 1600 ps/nm Application
TDM and WDM Applications
The PowerSource
TM
1915 LMM contains an DFB laser with monolithically integrated electro-
absorption modulator (EA-ILM). The modulation voltage is applied to the modulator section
while the DFB laser operates CW. Without the complexity of LiNbO
3
external modulators,
the PowerSource
TM
1915 LMM is dedicated to STM64/OC-192 bit rate with reduced size and
reduced cost. This device allows 10 Gb/s data transmission with an extinction ratio higher
than 10 dB and less than 2 V modulation voltage. The PowerSource
TM
1915 LMM is optimized
for 10 Gb/s TDM and WDM transmission systems supporting dispersion up to 1600 ps/nm.
FEATURES

LASER SAFETY INFORMATION
Take appropriate precautions to prevent undue exposure to naked eye. This product is classified Class 3A Laser Product according to
IEC-60825-1. FDA/CDRH Class IIIb laser product. All versions are Class IIIb laser products per CDRH, 21 CFR 1040 Laser. Safety
requirements under accession number 0120546-00.
HANDLING
This product is sensitive to electrostatic discharge and should not be handled except at a static free workstation. Take precautions to prevent
ESD; use wrist straps, grounded work surfaces and recognized anti-static techniques when handling the PowerSource
TM
