OLT4000E series is a fully C-band tunable externally modulated optical transmitter, with adjustable range up to 35nm, including the wavelength adjustable of 89 ITU standard channels in all C-band. The wavelength adjustable range is 1528.77 ~ 1563.86nm, with the interval of 0.4nm (50GHz) to precisely adjust the wavelength to meet the needs of different networks.

1.It adopts narrow bandwidth & low-noise DFB laser as signal source, and high linear LiNbO3 external modulator as external signal modulation.

2.The perfect pre-distortion circuit ensures perfect performance of CTB and CSO in high standard CNR value.

3.Advanced SBS dual band suppression circuit, SBS continuously adjustable, adjustment range: 13~19 for different distance networks.

4. Automatic gain (AGC) control enables stable output in different RF input levels.

5.Fully automatic case temperature control, intelligent fans, the fans starts to work when case temperature reaches 30 ℃.

6. Built -in dual backup power supply,hot plug in/out and automatic switching supported.

7.The operating parameters of the whole machine are controlled by  microprocessor, and the LCD status display on the front panel has many functions such as laser status monitoring, parameter display, fault alarm, network management, etc.; once the operating parameters of the laser deviate from the allowed range set by the software, the system will alarm promptly.

8. Standard RJ45 interface provided, supporting remote network management of SNMP and web, and remote adjustment of AGC, SBS, OMI and other functions.
