Alcatel 1928 OFA
D-WDM Straight-line
Erbium-Doped Fiber Amplifier
Description
The Alcatel 1928 OFA (Optical Fiber
Amplifier) is designed to offer excellent
performance characteristics for WDM
systems in the 1530 - 1560 nm wavelength
range.
The standard, double-stage 17 dBm unit
can be supplemented using an external
pump module to achieve 20 dBm output
power. Tap couplers at each signal port
offer full monitoring capability.
The Alcatel 1928 OFA achieves very flat
gain in excess of 22 dB or 26 dB, while
limiting gain excursion to < 1 dB (typical)
over the entire 30 nm wavelength range.
Optimization of the architecture yields very
low typical noise figures; < 5 dB for the 17
dBm configurations.
Features
•
Optimized for D-WDM transmission
•
Dual-stage 17 dBm basic unit can be
equipped with an external pump module
to offer 20 dBm output power
•
Low noise figure for optimal SNR
•
Flat gain across wide bandwidth range
•
Polarization independent & bit-rate
transparent
•
Optical isolators at input, monitor taps,
and output minimize system susceptibility
to reflection
•
Compact, rugged low profile package
Applications
•
Power booster for D-WDM systems
•
Low-noise in-line amplifier for transport
systems
•
Pre-amplifier for systems in which
dispersion compensation access is not
required.
