FX87 Overview
DWDM
– Dense Wavelength Division Multiplexing is a WDM technology characterized by
narrow, 0.4 nm (100 GHz) or 0.8 nm (50 GHz) channel spacing and grid wavelengths between
1530 nm to 1565 nm for C-band and 1565 nm
– 1625 nm for L-band and is typically used for
long range distances as found in Metro, Fiber Deep, and Core networks.
DWDM Spectrum Graph
The FX87 DWDM Tunable Laser Source is specially engineered to test DWDM systems
operating in C-band frequencies. The unit measures loss at the specified wavelengths with the
combination of the DWDM laser and optional broadband OPM with WaveID. The measurement
results can be transferred to a PC or uploaded to the cloud using a Fiberizer Cloud account.
To make the fiber identification in a rack more convenient, the laser signal from FX87 with a
calibrated wavelength (see the DWDM set of calibrated wavelengths above) is also modulated
with the following frequencies:
•
CW (Continuous Wave)
•
270 Hz
•
330 Hz
•
1000 Hz
•
2000 Hz
•

FX87 units are configured at the time of manufacture according to customer
requirements. A single device can be configured with Broadband OPM option and
upon special request for H62 channel addition.
