Product Description
EM23 is the sub-headend equipment for cable TV and broadband data access system, it has two low loss EOC signal insertion ports (i. E., up to 2 paths of IP data while support 128 terminals. ), two CATV signal input ports and two IP/CATV mixed signal output ports.
Features:
1. Water-proof case, small structure leads to convenient installation.
2. High quality switched power supply with perfect anti-surge (over-voltage) and under-voltage protection. High working stability.
3. Modular design. Convenient installation and maintenance.
4. Independent EOC signal inserter at each downstream signal output port.
5. An independent AC 60V power supply interface.
6. Two independent low-loss high-isolation EOC inserters, port isolation up to 100dB; Each path of EOC headend module is insured to play the best performance.
7. The combination of EOC signal and CATV signal will not affect the origin CATV signal at all.
