technical parameters
typical application
carrier-class reliability
supports fault detection and network management alarms.

low power consumption and high integration.

support three levels of lightning protection standards.

supports over-voltage over-voltage protection for pots interfaces.

smaller, higher-quality communications power supply with ripple protection, surge protection, power line bonding and other protections, stable output, high reliability, and instantaneous power-off protection are supported.

the use of shielded electromagnetic radiation characteristics of the chassis, the electromagnetic compatibility, rohs and other aspects of a professional design, can effectively shield all kinds of environmental electromagnetic interference.

transmission loss, loss frequency, nonlinear distortion, cross-talk attenuation, cross-over noise, and non-overlapped noises meet carrier-grade standards.
