・A cost-effective way of simulating DWDM signals, replacing costly banks of DFB lasers.
・Greatly reduces experimental set up and maintenance time.
・Features the same power-spectral density as a full set of DFB lasers.
・50 GHz spacing allows simulation of
　> 80 channels in the C band
(100 GHz spacing also available).
・Channels locked to ITU grid.
・High peak-to-valley extinction ratio
　(> 47 dB).
・High stability.
・Also available in L-band.

・The EBS-4015/EFA Broadband Source and Power Amplifier utilizes amplified spontaneous emission (ASE) from diode-pumped Erbium-doped fiber and a cleverly-conceived spectral-shaping scheme to produce more than 15 dBm of unpolarized output centered at 1548 nm and with a near flat-top spectrum; maximum ripple does not exceed 2.0 dB over most of the spectrum, namely 39-nm, while 3-dB bandwidth is larger than 40 nm.

・Output power up to 14 dBm
・Covers both C & L Band
・Flatness better than 3 dB over 76 nm

・The EBS-4022 Erbium Broadband Source is an extremely stable, flattened broadband source delivering 22 dBm in a 40-nm wide spectrum spanning the whole Erbium C band.
・ It utilizes amplified spontaneous emission (ASE) from diode-pumped Erbium-doped fiber and a spectral shaping scheme which flattens the output to better than 1 dB from 1527 to 1567 nm.

・Both C-band and L-band models
・Ultra-low-noise figure preamplifiers
・Wide range of power amplifiers
　(up to 23 dBm)
・Fast transient response
・Variable gain
・Mid-Stage access
・Gain-flattened preamplifiers and
　power amplifiers
・RS-232 interface

・To meet the demand for high output powers with sophisticated optical performance, MPB Communications offers its EYDFA Series. Designed for demanding DWDM and military applications, the EYDFA Series feature erbium-ytterbium booster amplifiers with saturated output powers of 2 W over 32 nm of the C-band with a gain flatness of ± 1 dB.

・Compact modular construction with
　remote control
・Air cooled
・Short, high peak power pulses
・Variable output energy
・Long thyratron lifetime

・Gain Flattening Filters
・Athermal packaging
・Wavelength Lockers for
　980nm/1480nm Pump Lasers
・Sensor Gratings

・Adjustment mechanism allows for easy, slip-free alignment and locking of the flap-like discs
・Mechanical design ensures very low polarization dependent loss
