What
is Optoplex core technology? |
|
| |
Optoplex's
products are based on its patented free-space micro-optics
technologies and state-of-the-art, in-house thin-film coating,
which are foundations for Optoplex's DPSK
demodulator, optical hybrid,
tunable optical filter,
reconfigurable
optical add/drop multiplexer (ROADM), optical
interleaver, optical
performance monitor (OPM), optical
channel monitor (OCM), portable
spectrometer engine and flat-top
comb filter. |

Are
Optoplex's products compliant with RoHS requirements? |
|
| |
Currently,
Optoplex's products are RoHS-5 compliant.

DPSK
Demodulators
|
|
| |
|
|
| |
How
many types of DPSK demodulators arecurrently available? |
|
| |
Three
types of DPSK Demodulators
are available: Passive (fixed), Fully tunable, and Semi-tunable.
|
|
| |
|
|
| |
What
(which parameter) is tunable on Optoplex's tunable demodulators?
|
|
| |
Frequency
alignment of the constructive and destructive outputs. For
a given device, its free spectral range (FSR) is not tunable.
|
|
| |
|
|
| |
What
is the tuning mechanism used in Optoplex's tunable DPSK
demodulators?
|
|
| |
Optoplex's
tunable DPSK demodulators
utilize the temperature-dependence of an optical part to
adjust the phase difference between the two interference
beams. The tuning is achieved by varying the temperature
of that part through a resistance heater.
|
|
| |
|
|
| |
What
is the difference between the fully tunable type and the
semi-tunable type?
|
|
| |
The
fully tunable DPSK demodulator
has wider tuning range and faster tuning speed compared
with the semi-tunable type.
|
|
| |
|
|
| |
What
is the advantage of each type?
|
|
| |
For
the passive DPSK demodulator,
the main advantages are the colorless application (each
device with 40- or 50-GHz FSR can be used for all DWDM channels
and no need for electric power and the control circuit.)
For the fully tunable DPSK
demodulator, the user usually choose the FSR to exactly
match the signal rate. The main advantage is the ability
of tracking signal frequency drift (laser aging; temperature
dependence; transmission related frequency chirp) to avoid
OSNR penalty. The semi-tunable type combines the advantages
of the passive and fully tunable type. It maintains the
colorless feature (by choosing 40- or 50-GHz FSR) while
gaining some degree of frequency-tracking ability.

Optical
Interleavers |
|
| |
|
|
| |
Can
Optoplex provide optical interleaver with channel center frequency
offset from the ITU grid? |
|
| |
Optoplex
optical interleaver
platform is flexible in frequency alignment. Please specify
your interleaver channel plan upon ordering. |
|
| |
|
|
| |
Can
Optoplex provide asymmetric optical interleaver? |
|
| |
Yes.
Optoplex provides both symmetric
optical interleaver and asymmetric
optical interleaver. |
