OPT-1550E-NGB Series 1550nm external modulation optical transmitter is a leading products for new generate broadcasting networks, wavelength tunable within full C-band: 1528.77~1563.86nm.tunable width ≥35nm. it is a completely new concept compared with traditional ITU wavelength ±0.8nm (±100GHz)
OPT-1550E-NGB contains all of useable wavelengths in C-band; users can select, switch and manage the wavelength according to the network demands. It can be applied to NGB DWDM system
Features
1) High quality: original system optimization control technology and RF pre-distortion technology
ensure that the system can acquire the maximum CTB, CSO, and SBS targets in the case of excellent performance CNR≥53dB
2) Flexibility: In ensuring the high performance system CSO, the phase modulation technology of external modulator maximize the optical power into the fiber in order to obtain long-distance transmission, and the field adjustable SBS threshold, 13~19dB, OMI and ITU wavelength adjustable
AGC/MGC mode selectable, suitable for different networks
3) 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.
4) 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.
5) Power supply Pluggable: adopts aluminum material, pluggable switch PSU, work with 86~265VAC, it can be replaced with -48VDC easily.

Note：
1) In the condition of stipulated link-loss, configured in 59 PAL-D analog television channel signals within 550MHz frequency, in the range of 550MHz ~ 750 (862) MHz frequency transmit digital modulation signals, digital modulation signal level ( in 8MHz bandwidth) is 10dB lower than the analog signal carrier level, when the optical input power is 0dBm, you can measure the carrier combination triple beat ratio (C / CTB), carrier combination of second-order beat ratio (C / CSO) and the carrier to noise ratio (C/CNR)
