产品摘要详细参数产品图片

Fibercore’s MetroGain™ range is designed for high efficiency ‘Metro-style’ Erbium Doped Fiber Amplifier (EDFA) configurations, single stage amplifiers, Amplified Spontaneous Emission (ASE) light sources and single channel or few channel EDFAs.
M-5(980/125) offers a relatively low level of doping to simplify EDFA manufacturing processes by reducing the sensitivity of the amplifier output to the precise gain length.
M-12(980/125) gives high absorption levels to allow short gain lengths and reduced material costs.
M-12(980/80) is an 80μm variant, benefitting from the higher absorption of the standard M-12(980/125) but allowing significantly longer mechanical lifetimes when used in small coil diameters, particularly important for small form factor EDFA designs such as mini EDFAs and micro EDFAs.
M-3(1480/125) is designed for pumping at 1480nm, accessing higher pump conversion efficiencies than pumping at 980nm.

 

Advantages:
• High conversion efficiency
• High absorption variants available for short amplifiers and EDFAs
• 80μm variant for small coil diameter applications

 

Typical applications:
• Erbium Doped Fiber Amplifiers (EDFAs)
