OPTICAL PRE-AMPLIFIER: PRELIMINARY SPECIFICATION Description This high gain semiconductor optical amplifier is primarily intended for use as an optical pre-amplifier in high bit rate applications (10 Gbit/s and 40 Gbit/s). Its high gain and low noise figure provide a high performance, compact and price competitive alternative to single channel EDFAs in receiver subsystems.The optical pre-amplifier package includes a thermistor and thermo-electric cooler in a 14-pin butterfly package with single mode fiber pigtails. Applications F E AT U R E S This product is appropriate for both metro and long haul applications where the use of an optical pre-amplifier increases the sensitivity of the receiver system, particularly where high data rates are used.The same device is also appropriate for use as an in-line single channel amplifier for metro/access applications. 1550nm WINDOW HIGH GAIN LOW POLARISATION DEPENDENCE LOW NOISE FIGURE COMPACT PACKAGE Specifications PARAMETER Fiber-to-fiber max gain Noise figure Saturation output power Gain ripple at max gain Polarisation dependence 3dB optical bandwidth Gain centre wavelength Bias current Operating temp TEC drive max MIN SPECIFICATION TYPICAL SPECIFICATION 20dB 25 dB 7dB 6 dBm 0.2 dB 0.2 dB 50 nm 1550 nm 150 mA 5 dBm 40 nm 1540 nm -5 deg C MAX SPECIFICATION 9dB 0.3 dB 0.3 dB 1560 nm 200 mA 65 deg C 1.5A/4V
