The Laser Link® Modular 1550 nm Optical Transmitters are part of an advanced transmission system designed to optimize network architectures and increase reliability, scalability, and cost effectiveness.
The Laser Link 1550 nm Transmitter Family includes the Externally Modulated Transmitter (LEMT), Narrowcast Transmitter (LLNT), and Narrowcast Return Transmitter (LLNTR). These 1550 nm transmitters are designed to operate over a wide range of optical output powers and loss budgets, delivering both analog and digital signals.
The 1550 nm LEMT applications include supertrunking, hub interconnects, broadcast transmission portion of DWDM architecture and 1310/1550 nm overlays. The LLNT converts input RF narrowcast signal in the 50-870 MHz frequency range to an optical output with a discrete ITU grid wavelength. LEMT Transmitter Multiple outputs of LLNT products (20 currently) may then be transmitted over a single fiber through utilization of wave division multiplexing. The LLNTR converts RF signal inputs in the 5-210 MHz frequency range to an optical output with a discrete ITU grid wavelength. LLNTR outputs of differing wavelengths may then be combined for amplification and transport over a DWDM system.
