PRODUCT FEATURES

High quality

Original system optimization control technology, RF predistortion technology to ensure excellent performance in the case of CNR system to obtain the largest CTB, CSO and SBS indicators.

Flexibility

Phase modulation technology of the external regulator to maximize the performance of the system CSO, to maximize the fiber into the optical power to obtain long-distance transmission, and SBS threshold 13,16,18 field adjustable , Can be applied to different network transmission.

Reliability

19 "1U standard rack, built-in high-performance dual switching power supply, can be 85 ∽2665ac city network voltage in the hot backup work, MS-level automatic switch; chassis cooling can be automatic temperature control.

Intuitive

External modulator and laser is the most expensive device, the machine set up a microprocessor outside the tune.
And the working state of the laser is monitored, and the operating parameters are displayed by the panel LCD window.

Network management

Option status monitoring transponder to ensure compliance with the national standard and compatible with the SCTE HMS standard, can achieve network management monitoring.

Butterfly laser: ORTEL

Butterfly laser with refrigeration, which ensures that the laser works at a cer
ain wavelength and has high power.

Coaxial laser: ORTEL

An analysis of relativistic electron
motion in a free electron laser with co-axial wiggler and ion-channel guiding

is presented
 

MODULATOR

The purpose of an REmodulator is to ensure that the signal provided by the carrier can
travel from place to place.
