Product Capabilities and Value
Higher power amplifiers or new amplification methods are needed as
system designers attempt to transmit more channels over longer
distances. Raman amplification has emerged as a method to complement
EDFA designs for ultralonghaul signal transport. These new amplifiers
require multiple high-power pump lasers, creating a need for a pump
laser combiner that can handle 1 watt or more of pump power.
The WavePump is a reliable, low-loss, all-fiber pump laser combiner for
use in Raman or EDFA amplifier designs. The Fused Cascaded
Fiber
(FCF) approach offers an intrinsically low loss design while allowing
many pump lasers to be combined to achieve high amplification. High
pump power levels are easily handled with the WavePump; the WavePump
has been tested to several watts of input power. The available
wavelengths cover the Raman pump wavelengths band.
The flexibility in wavelength and pump channel spacing are especially
useful in Raman amplifier design and allow you to optimize the Raman
gain.
WaveSplitter understands that excellent performance is just one of the
many selection criteria for choosing a pump laser combiner, and the
WavePump has been designed to meet high reliability standards.
Finally,WavePump offers a lower-cost alternative to other methods of
combining pump lasers. When you combine the technical benfits of
low-loss, multiple channels, and high power handling capability with
the TelcordiaTM
reliability and value, the WavePump makes an excellent choice to meet
your Raman amplifier design golds. |
