1. Product overview
Thor Fiber 1550nm RF directly modulated optical transmitter with electronically controlled dispersion
compensation. It supports up to 1.2GHz band and DOCSIS 3.1 system. With two RF inputs and high
isolation, it enables the signal transmission of QAM and IPQAM smoothly. Supports a transmission
distance of 50KM with electronically controlled dispersion compensation. Built-in CWDM is optional for
multi-wavelength networking.
2. Performance Characteristics
1.2GHZ band, support DOCSIS 3.1 system.
The AGC and MGC gain control modes are optional.
Two inputs with 50dB isolation for high quality RF insertion.
Dual power supply; hot backup; a variety of power supply options are available, optional AC100-240V
and DC48V.
Laser output power, bias current and cooling current are detected in real time.
Optional CWDM for optical signal insertion.
Electronically controlled dispersion compensation can support a transmission distance of 50KM.
Low-cost solution is comparable to the performance of external modulated transmitter.
ITU standard wavelength is optional.
3. Block Diagram
Note: The optical attenuator in the red dashed box and the wavelength division multiplexer in the
blue dashed box are optional.

8. Attention
Ensure the package is not defaced. If you think the equipment has been damaged, please don't electrify
yourself. Check all contents carefully
Before the equipment is powered on, make sure the housing and the power socket is reliably
grounded. The grounding resistance should be <4Ω, so as to effectively protect against surges and
static electricity.
The optical transmitter is a professional device and its installation and debugging must be operated
on by a special technician. Read this manual carefully before operating to avoid damage to
equipment caused by fault operation or accident harm to the operator.
While the optical transmitter is working, there is an invisible laser beam coming from the
optical output adapter on the rear panel.
To avoid permanent harm to the body and eye, the optical output should not be aimed
at any human or looked at with the naked eye!
When the fiber connector is not in use, it should be housed with a dust jacket to avoid dust pollution
and to keep the fiber tip clean.
