Control features include laser shut down and manual or automatic gain control, which is controlled via the front panel keypad on the OCM user interface or managed remotely using the OCM network management system, NMS3.
Light Link ? Series 3 optical transmitters incorporate a comprehensive alarm and status monitoring system of all laser operating parameters such as DC laser bias current, cooler current and optical output power. These parameters are available for either local or remote-site monitoring.
The LTM15 suits single mode optical fibres with or without dense wavelength division multiplexing (DWDM). The transmitter can be used with erbium doped fibre amplifiers (e.g. PBN's EDFA or EDFAM) in short haul fibre-to-the-home (FTTH) applications with a maximum of up to 10 km of normal fibre, or up to 30 km on fibres with 1550 nm low dispersion.
The Light Link ? Series 3, LTM15 optical t ransmitter module has been designed to complement the OCM system with optical transmission in the 1550 nm wavelength range. The transmitter employs high performance, thermally stabilised DFB low-chirp isolated lasers to transmit AM-VSB CATV or DVB-QAM signals on one ITU frequency grid optical wavelength within the 1550 nm range.
