The iConverter microNID is a low-latency, compact and cost-effective Network Interface Device (NID) that provides service activation testing, fault and performance monitoring. The two-port microNID enables the delivery of service-assured Business Ethernet, 4G/LTE macro cell and metro/small cell backhaul services.

The microNID enables Service Providers to deliver premium services with Service Level Agreements where cost, space and power consumption are constraints. Cable MSOs can deliver value-added commercial Ethernet services and wireless backhaul over their existing DOCSIS networks with guaranteed Quality of Service.

The microNID is available with two SFP ports, two RJ-45 ports, or one SFP and one RJ-45 port. The SFP ports support 100BASE-X or 1000BASE-X fiber transceivers, 100/1000BASE-T and 1000BASE-T copper transceivers. The RJ-45 ports support 100/1000Mbps bridging, with auto-negotiation for data-rate and duplex mode. The RJ-45 ports also support auto MDI/MDI-X, eliminating the need for crossover cables.

The microNID provides circuit provisioning, Service Activation Testing, Service OAM, and timing synchronization at the demarcation point in applications where traffic management and Class of Service are deployed at the head end, central office, or network edge.

Integrated ITU-T Y.1564 and RFC 2544 test heads provide multi-flow Service Activation Testing (SAT) of throughput, latency, jitter and frame loss at full wire speed. The microNID also supports 3rd party loop-up/loop-down service activation testing at full line-rate.

The microNID features real time OAM Performance Monitoring and Fault Management functionality. It supports IEEE 802.1ag Connectivity Fault Management, ITU-T Y.1731 Performance Monitoring and RFC 5357 TWAMP Performance Monitoring for both Layer 2 and Layer 3 networks.

The microNID can be powered with an external AC to DC power adapter, with direct DC power, or through the RJ-45 port with 802.3af/at compliant PoE Power Sourcing Equipment (PSE).

The microNID can be remotely managed via TELNET, SNMPv1, SNMPv2c and SNMPv3, and is integrated into Omnitron’s NetOutlook® Network Management Software and NetOutlook® Element Management System. It can also be managed by third party management and performance portals.

Service Provider Application

In this application diagram, a Service Provider fiber access network provides Carrier Ethernet connectivity for business services and mobile backhaul services (for a Small Cell and 4G/LTE Macro Cell). An iConverter XM5 Aggregation NID is deployed at a hub location on a 10G fiber ring. The XM5 Aggregation NID provides traffic management and Class of Service prioritization for the Carrier Ethernet services.

The Service Provider deploys copper-to-fiber and a copper-to-copper microNIDs at the demarcation to provide performance monitoring and fault management for SLA assurance, and synchronization timing for the backhaul circuits.



Cable MSO Application 

In this application, a Cable MSO is providing backhaul services to a Wireless Operator with connectivity to a small cell. The Cable MSO is also providing Ethernet business services to a customer within their network.

A 10G fiber transport link connects Cable MSO Network to the Wireless Operator Network with a pair of iConverter XM5 10G NIDs. The iConverter XM5 10G NID at the Cable MSO network provides ENNI demarcation, traffic management and Class of Service prioritization for multiple Ethernet Virtual Connections (EVCs).

A Cable Modem Termination System (CMTS) at the Cable MSO’s hub location distributes coax links terminated with cable modems at the remote locations.

The Cable MSO deploys an iConverter copper-to-copper microNID at the small cell site to provide performance monitoring and fault management for SLA assurance, and synchronization timing for the backhaul circuits. A iConverter GM4 is deployed by the Wireless Operator to provide performance and fault monitoring between the Small Cell site and the WIreless Operator Network.

The Cable MSO is also providing a commercial Carrier Ethernet business service by deploying an iConverter copper-to-copper microNID with a cable modem at the customer premise for the SLA assured commercial service.
