Simbol Test Systems
is the one-stop shop for all your fiber optic test equipment and measurement
needs. As we are exclusively focused on e-commerce and international distribution of photonic
products since 2000, our customers rely on the
thousands of used and refurbished popular test equipment. They know they can get repair,
customization and calibration services from our laboratory for their own fiber optic instruments
from all renowned brand manufacturers.

ILX LDC-3916, LDC-3908, LDC-3926 and all modules. Trust
the Simbol Test Systems expertise
With more than 20 years of expertise in repair of OSA, Tunable Lasers, Wavemeters, Laser
drivers and controllers, and many more, the quality of our services is renowned amongst the
service centers community and highly appreciated by our partners and customers. We developed
custom software allowing fast testing of Laser controllers racks and modules. Each module is
tested with a butterfly laser attached to it to ensure all its control functions are per specifications.
Each shelf is tested with a full load of modules. That is the only way to know a shelf can be used
at 100%. Don't settle for a two-page summary assessment to trust that your Laser Diode
Controller shelf or any Laser Control module is operating properly; our report contains the
complete table of all results, confirming it has really been tested. A report from other labs with
less data reflects a not completely calibrated unit. So be careful of other sellers saying their
equipment is "tested good", "powered on, self-tested", "pulled from a working environment". When
you choose AssetRelay, you can be confident that we actually test everything we sell so you know
it will work when it gets to your workplace.
Simbol Test Systems ILX Laser Controller modules and racks tests
The ILX LDC-3916, LDC-3908 and LDC-3926 mainframes sold by AssetRelay or Serviced by
Simbol Test Systems will go through a series of tests to ensure it meets or exceeds
manufacturer's published specifications. The equipment is shipped with a comprehensive
calibration/test report showing all performed and passed test. A dated calibration sticker is affixed
on the machine.
ILX LDC-3916, LDC-3908, LDC-3926 tests on report:
- Module Communication
- Front Panel Test
- Temperature Control
- Laser Power Control
Traceability: Instrumentation used during this calibration is traceable to N.I.S.T (National Institute
of Standards and Technology) or C.N.R.C. (Canadian National Research Council).
