LMC10ZEG

Data Sheet 10Gb/s Compact InP MZ Modulator with DWDM Laser LMC10ZEG Zero Chirp - High Power The LMC10ZEG product, containing the Bookham Ultra High Power Strained Layer DFB laser chip and Zero chirp InP MZ modulator, has been specifically designed for use in 10 Gb/s high performance regional metro and long haul C band DWDM systems. By co-packaging the laser, locker, modulator, VOA in a package with the same footprint area as the industry standard 14-pin, the LMC10 series provides Mach-Zehnder performance at a price similar to lower performance alternatives. The internal optical attenuator allow fibre power stabilisation over life and temperature. The high output power, integral wavelength locking and high extinction ratio provides excellent OSNR to allow the device to be employed on multi-span long haul links. Features: • Variable mean modulated optical power range of 0 to -10dBm • Zero Chirp +/-0.2 alpha • Co-planar differential RF drive ≤3.0 volts • Suitable for 50GHz ITU applications with +/-20pm λ accuracy over life • Low Power Dissipation • Industry Standard 14-pin footprint area • Pins on one side to allow increased system density • Unrivalled performance vs size • Integrated VOA • Qualified to Telcordia GR-468 CORE • RoHS 5/6 compliant Applications: • Long Haul DWDM multi-span dispersion compensated links • Regional Metro single spans with no dispersion compensation 1 Data Sheet Using the LMC10ZEG The recommended operational conditions for the LMC10ZEG are as follows: MZ modulator arm DC bias conditions are set at start of life (SOL), (dynamic MZ DC bias control loops are not required). The VOA can be used in a control loop to set the start of life optical output power.
