Product Description

ITU All C Band Turnable CATV 1550nm  External Modulated Optical Laser Transmitter

Product Description
EOT55XXI series all band tunable 1550nm external modulation optical transmitter, is an pioneer and new product from our company which D&R, design and production ourselves. The turnable range of wavelength: 1528.77~1563.86nm, the adjustable wavelength >35nm. With the traditional standard wavelength ±100GHz adjustable, is a completely new concept.
EOT55XXI Series including all can using wavelength of C-band.(CATV wavelength valid range: 1540~1563nm) Users can achieve the selection, swith quickly, accurately, convince the selection demand of DWDM system.


1. Module Design, easy to installing and maintaining
2. 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
3. Flexibility: the modulator technology of external modulator insure 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.
4. 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.
5. Network type: Select All-piece status monitoring transponder guarantee to meet the national standard and be compatible with the SCTE HMS standard, it enable network management monitoring capabilities.
6. Plug in type power supply: adopt aluminium 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.
