2B454
VCSEL Laser Diode
Datacom
This Vertical Cavity Surface-
Emitting Laser is designed for Fibre
Channel, Gigabit Ethernet, ATM and
general applications. It incorporates a
photodiode to monitor the optical
power and allow for feedback control.
For eye safety, the optical power is
attenuated to comply with IEC Laser
Class 1 requirements.

PRODUCT INFORMATION
SC-2A
Package
Emitter or Detector in SC Package
Mitel emitters and detectors can be
provided in this low-profile SC pack-
age. The device is electrically isolat-
ed from the SC receptacle to facil-
itate electrical connection. And opti-
mum fiber-coupled power or respon-
sivity is ensured by active alignment
against the fiber..
