1550 nm Forward Transmitter - Enhanced


About the Product

The 1550 nm Forward Transmitter - Enhanced (FT5E) is designed to plug into PBN's latest Advanced Intelligent Multi-services Access platform - the AIMA3000.

PBN's AIMA3000 FT5E series features full-spectrum enhanced forward transmitters engineered for multi-services operators (MSOs) to increase network capacity to satisfy an ever-growing subscriber demand for bandwidth. The module's operating wavelength conforms to ITU standards and works with PBN's Erbium Doped Fiber Amplifier Module (EDFA). It allows for full-spectrum analog/digital broadcast and narrowcast channels, providing the utmost flexibility for MSOs during the transition to all-digital.

The FT5E employs an advanced RF circuit design and a high quality / lowchirp laser. The module offers a superior frequency response, as well as low distortion and noise characteristics. In addition, it has a cutting-edge optoelectronic design for the delivery of high-quality transmissions, in both analog and digital formats, over passive fiber optic networks.

All FT5E models can also be conveniently monitored and controlled through a computer connected to one of the Ethernet ports via the ASMM module. All module settings are retained in non-volatile memory to ensure trouble-free operation. Bulk updating, automatic uploading and downloading of configuration files can be done when using PBN's NMSE web-based management system.
