Node Quang Một Chiều ZHT (OFR-UOR-002) C-LINK Phân Phối

Specifications:

Electric integration RF module, Low noise, low distortion, low optical powerUsing high quality NXP or NEC module, make sure good C/N,C/CSO,C/CTB data for the network..Multistage optical signal indicationUsing plug-in devices with guiding groove, could achieve blind mating. Asymmetrical stitch of the equalizer had been designed to avoid incorrect using. Gilded copper stitches and pins are suitable for contacting and debugging. The standard optional output interface: 2/3/4outputs,2 high power output etc. Built-in two aluminum panels to prevent electromagnetic radiationMultistage lightning protection devices ensure long-time stable and continuous working in an adverse environment. New attractive aluminum alloy case with waterproof, moisture proof and anti-Oxidation design is favorable to installation and heat elimination. Intelligent: RG-45 Ethernet interface is optional, for implementing a monitor system under <GB/T 20030－2005 Specification of Equipment Management System of HFC Network>
