Sourcing 16e1+100m fiber opitic pdh multiplexer from Beijing Raycomm Digital Technologies Co., Ltd - China Import Guide
Before procuring this PDH multiplexer from Beijing Raycomm Digital Technologies, request the complete technical manual and compliance documentation. Verify the exact optical connector type (FC or SC) for your patch panels and the power cable specifications for your site's -48VDC or 220VAC supply. Ask for the specific SNMP MIB details if remote management is required.
Confirm all commercial terms directly with the supplier. Negotiate the lead time for your required quantity, the Incoterms for shipment (e.g., FOB Beijing), and the payment terms. Inquire about warranty coverage, typically one to three years for telecom equipment, and the process for obtaining technical support or replacement units.
Upon delivery, conduct a thorough acceptance test. Verify the E1 channel integrity using a BER (Bit Error Rate) tester and confirm the Ethernet port auto-negotiation and VLAN functionality. Test the 1+1 optical protection by simulating a fiber failure to ensure seamless switchover. Document the unit's serial number and configuration for your network asset management system.
