Four-channel optical receiver

1040V is a high-end four-output CATV network optical receiver that can be equipped with a network management module and can operate in both directions. The preamplifier of this device uses all gallium arsenide MMIC amplification, while the postamplifier is a gallium arsenide module amplifier. The optimized circuit design, combined with the company's many years of professional design experience, has enabled this device to achieve high performance indicators. The attenuation and equalization of the RF signal are all adjusted using continuous adjustable attenuators, making the engineering debugging extremely convenient. It is the mainstream model for building CATV networks.

II. Performance Features

Optical AGC control. When the input optical power is -7 to +2 dBm, the output level remains basically unchanged, and CTB and CSO remain basically unchanged.

Ten light-emitting tube power indicators, providing more accurate RF power display.

Optimized circuit design. The classic circuit of the preamplifier using SMT technology and the postamplifier using module amplification, with better linear RF signal.

The RF attenuation and equalization adjustment of the downstream optical receiving part are all using adjustable attenuators, allowing continuous adjustment of the signal level; the RF of the upstream optical transmitting part all uses fixed attenuators, and by inserting attenuation plugs at the EQ position, the equalization amount can be changed, making the engineering debugging extremely convenient.

Power multiplication output, with high gain and low distortion.

The output level can be selected according to the different configuration of the module.

It can operate in both directions, with plug-in filters, and the frequency division point can be freely changed according to the user's requirements.

A complete RJ45 SNMP network management system, with built-in international Class II network management responder, supports remote network management (optional).
