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 • Direct signal amplification at 1550 nm • Optimized for AM-VSB analog transmission • High optical output power (+17 dBm) single pump design • Low-noise figure for optimal CNR • Minimal gain tilt for optimum CSO/CTB • Output (optional at input) optical isolator minimizes system susceptibility to reflections • Compact, rugged low profile package Applications • Power booster for CATV and Hybrid Fiber Coax (HFC) networks • Low-noise post-amplifier for transport systems Optical characteristics Parameter Condition Output power [1] Input power Operating wavelenght Noise figure Polarization mode dispersion Gain tilt Input/output optical return loss CSO contribution CTB contribution Min Typical Max +6 1555 + 10 1560 6 0.5 + 0.25 + 16 1550 - 0.25 33 0 Unit - 65 - 70 dBm dBm nm dB ps dB/nm dB dBc dBc Max Unit 300 2.5 1500 1.5 4.0 10.5 16 16 mA V A µA V k µA/mW µA/mW Notes : Parameters are start of life.
