NX8570
NX8570 is LASER DIODE manufactured by CEL.
DESCRIPTION
The NX8570 Series is a 1 550 nm Multiple Quantum Well (MQW) structured Distributed Feed-Back (DFB) laser diode module with wavelength monitor function. This device is temperature tunable over 4 × 50 GHz channels. Available at both C-band (1530.334 to 1565.087 nm) and L-band .. (1565.496 to 1608.760 nm) ITU-T grid wavelengths. This device is designed as CW light source and ideal for transmission systems in which external modulators are used.
FEATURES
- Wavelength monitor function (Etalon Filter, Wavelength monitor PD)
- Optical output power: Pf = 20 m W MIN.
- Available for DWDM wavelengths based on ITU-T remendations (50 GHz grid)
- 4-channel wavelength tunable capability for 50 GHz-spacing (NX8570S××××D)
- Internal thermo-electric cooler and isolator
- Hermetically sealed 14-pin butterfly package
