Models
The Optical Spectrum Analyzer comes in different models:
³
FTB-5240S: The FTB-5240S is a small form factor expert OSA (two-slot
unit). It offers new modulation schemes, such as non-return-to-zero
(NRZ), duo binary, differential phase-shift keying (DPSK), quadrature
phase shift keying (QPSK), which present large line widths and often
display multiple peaks. In-depth analysis ensures the correct
identification and signal measurement of each carrier.
³
FTB-5240S-P: It is the FTB-5240S model with a polarization controller. It
is a hardware-ready version of an expert OSA (two-slot unit), without
the software to compute the In-Band OSNR. You can upgrade this
model on field using the software key, and it will become fully capable
of In-Band OSNR measurement.
³
FTB-5240S-P-InB: It is the FTB-5240 S-P model (two-slot unit) with the
addition of an automated and integrated polarization controller. It is
possible to change the state of polarization (SOP) at the input of the
OSA and take advantage of a polarization diverse design to determine
the OSNR in the band of a DWDM channel. This is required when noise
is not flat under adjacent peaks or when crosstalk is dominant.
³
FTB-5240BP: It is a three-slot model with a polarization controller for
automated In-band testing and better optical performance.
³
High Power Model (HPW): This model allows you to connect the
FTB-5240S or FTB-5240S-P OSA to a network that carries very high
optical power. This situation becomes more common with the
deployment of latest CATV networks. The sensitivity of this OSA model
is shifted accordingly and the module is protected to work under these
extended power levels.
