Fiber Port Options
The 2GXM Small Form Pluggable (SFP) model supports a wide variety of SFP transceivers for FTTX and CWDM applications. SFP fiber transceivers are available with multimode (MM) dual fiber, single-mode (SM) dual fiber and single-mode single-fiber (SF) options. They support LC connectors with distances up to 550m over MM fiber, 140km over SM fiber and 40km over SF. SFP transceivers are available in 20nm increments from 1270nm to 1610nm to support FTTX and CWDM applications.
Link Modes
The 2GXM features multiple, user-selectable link fault detection modes, including Link Propagation, Remote Fault Detection and Symmetrical Fault Detection. These Link Modes provide rapid fault detection and isolation by monitoring the state of the cabling hardware, and operate independently of the network management.
Tag VLAN, Port VLAN and QoS
The iConverter 2GXM supports the IEEE 802.1Q Virtual Local Area Network (VLAN) packet tagging and untagging and the 802.1p Quality of Service priority standards.
2GXM VLAN tunneling technology enables service providers to offer their customers E-Line and E-LAN services (also called Ethernet Virtual Channel or EVC), which connect different business locations and make their networks appear to be on the same local network. VLAN technology transparently transports customer network traffic across the service provider network, and isolates it from other customer traffic and the service provider management traffic.
2GXM Port VLAN enables the ability to specify and restrict traffic flow between the fiber, backplane and management ports.
The 802.1p prioritization standard enables delivery of Quality of Service (QoS) to high-priority, real-time applications such as voice and video over Ethernet.
Port Access Control
The 2GXM features Port Access Control which blocks user service while maintaining the network link. Port Access Control enables the service provider to control user access while maintaining port configuration for easy disabling or enabling of customer service. Port Access Control provides enterprise administrators the capability to improve network security by controlling port access when the port is not in use.
Port Statistics and Optical Performance Statistics
The 2GXM supports reporting of utilization, port and optical performance statistics. Port statistics are available for 38 different variables for the fiber ports. Additionally, full optical performance statistics are available on SFP fiber transceivers with a digital diagnostic bus.
Port and optical performance statistics reporting provides the ability to monitor customer bandwidth utilization, network performance and the link signal quality for each individual port.
IEEE 802.3ah Operations, Administration and Maintenance
The 2GXM supports the IEEE 802.3ah OAM standard, including Fault Detection, Performance Monitoring and Remote Loopback.
Fault Detection
The 2GXM detects and indicates link failures, dying gasp and other critical events.
Performance Monitoring
802.3ah Performance Monitoring tools are used for the detection and notification of link performance (quality) faults. Ethernet data performance can deteriorate slowly before disrupting service, and the 2GXM allows the setting of error-per-second thresholds. Once the pre-set error threshold is exceeded, an event notification is generated that provides early indication of a problem that may be resolved prior to loss of service.
Remote Loopback
Remote Loopback is used for fault localization and link performance testing. When a 2GXM port is in loopback mode, all received service traffic is looped back and transmitted back unaltered. The statistics from the 2GXM port and the remote link partner can be compared for consistency.
