1550EA
1550EA SERIES ITU ALL C-BAND TURN-ABLE EXTERNAL MODULATION OPTICAL TRANSMITTER
Features
◆High quality: the original dual microwave innovative new technology, RF predistortion technology insure in the situation of quality CNR=53dB, system can get largest CTB.CSO. SBS index.
◆Flexibility: the modulator technology of external modulator insures CSO performance excellent, improve fiber optical power maximum, get long distance transfer. SBS: 13-19, OMI, ITU wavelength adjustable, AGC/MGC selectable, apply for different network.
◆Intuitive: The laser is the most expensive machine components, machine equipped with microprocessor monitors the working state of the laser, the panel LCD window displays the operating parameters.
◆Network type: Select All-piece status monitoring transponder guarantee to meet the national standard and be compatible with the SCTE HMS standard, it enables network management monitoring capabilities. (Plug in type power supply): adopt aluminum profile plug in type switch power supply, it can work at 85 265Vac City Network Voltage, As well as an optional DC48V power supply (reservations required); chassis cooling automatic temperature control.
