Alcatel 1911 OFA
Erbium-Doped Fiber Amplifier
Analog Module
Description
The Alcatel 1911 OFA Erbium-Doped
Fiber Amplifier (EDFA) is a power
booster designed for use in analog
applications.
The Alcatel 1911 OFA has been
optimized for low-noise figure and gain
tilt to ensure minimal degradation of the
CNR, CSO and CTB of your analog
transmission system. The use of optical
isolation at the output of the amplifier
(optional at input) ensures that
reflections from unmatched connectors in
the system do not affect amplifier
performance.
Features
鈥?Optimized for AM-VSB analog
transmission
鈥?High optical output power
(+17 dBm) single pump design
鈥?Low-noise figure for optimal CNR
鈥?Minimal gain tilt for optimum
CSO/CTB
鈥?Output (optional at input) optical
isolator minimizes system susceptibility
to reflections
鈥?Compact, rugged low profile package
Applications
鈥?Direct signal amplification at 1550 nm
鈥?Power booster for CATV and
Hybrid Fiber Coax (HFC) networks
鈥?Low-noise post-amplifier for
transport systems
