over fiber optic networks. The instrument integrates the latest-generation digital signal
processor with a control and management implementation to deliver suitable performance in
a module that can be integrated into network
equipment. It complies with the OIF 100-Gb/s
MSA Implementation Agreement. It uses a low-power digital signal processor large-scale integrated circuit supplied by NTT Electronics Corp.
Explosion-Proof LED Light
It operates on 2-W power input at 100 and 240
VAC, 50 to 60 Hz, and on laser diode input of
393 mA at 5 VDC, for full output power. The
highly collimated output appears as TEM00, with
a focal point of ≤500 µm. Additional collimation
allows for transmission at distances of >1 km.
The 4 ; 6 ; 5-in. laser enables new research
in fluorescence lifetime studies, materials, di-rect-diode laser pumping of dye liquid lasers,
laser ablation spectroscopy, laser marking and
engraving, micromachining of organic materials, forensic studies, near-UV laser illumination,
laser light shows, laser projection systems
and displays, and counterfeit detection.
Elk Industries LLC
Princeton Optronics Inc.’s single-mode near-
infrared vertical-cavity surface-emitting lasers
(VCSELs) offer output power up to 100 m W.
Suitable for applications including sensing,

Larson Electronics LLC has introduced an explo-
sion-proof surface-mount infrared LED light de-
signed to provide illumination in the 1145-nm
range normally applied in spectroscopic testing
and analysis applications. The EPL-SMLED-20W-
1445 is designed for Class 1 Division 1 loca-
tions and produces infrared light without lenses
or filters. Cool running and portable, it is suit-
able for use in wet or corrosive environments
and can be operated in the range of 9 to 48
VDC. Designed for analysis processes such as
infrared spectroscopy, the 1445-nm light is in-
visible to the naked eye and suitable for spe-
cialized applications where testing and observa-
tion of molecular structures and chemical
composition are performed. A flat base with
preformed mounting slots provides secure, per-
manent mounting to flat surfaces.
