STM-1 to Ethernet 10/100BaseT converter

AN-STM-1-ETH is designed as a STM-1 level optical modem with two 155.520Mb/s optical interfaces to provide a cost-effective and flexible multi-service platform. With 4 Ethernet interfaces compatible with IEEE 802.3/802.3u standard, it is easy to implement Ethernet transmission over SDH.

  • Optical Interface

    • Two STM-1 interfaces, SFP optical module (LC connector), hot plug-in

      •  Complies with GB/T15941-1995 and ITU-T G.813 standards

      •  Supports RPD (Remote Power down Detection) information sending function

    • Supports ALS (Automatic Leaser Shutdown) to protect operators from hurt

  • Ethernet Interface

    • Four LAN ports(physical port), each LAN port supports auto-negotiation, it can also be set to 10M full/half-duplex, 100M full/half-duplex mode by force

    • Four WAN ports (internal port and invisible), each WAN port employs a VCG; the total bandwidth of 4VCGs is 63 VC12 and the bandwidth of each VCG is up to 48 VC12(100Mbps)

    • The LAN and WAN ports are compatible with IEEE802.3/802.3u standard

    • Supports flow control and broadcast storm filtering control

Description

AN-STM-1-ETH is designed as a STM-1 level optical modem with two 155.520Mb/s optical interfaces to provide a cost-effective and flexible multi-service platform. With 4 Ethernet interfaces compatible with IEEE 802.3/802.3u standard, it is easy to implement Ethernet transmission over SDH.

AN-STM-1-ETH supports port-based VLAN and IEEE 802.1Q tag-based VLAN. By adopting ITU-T G.7041, G.7042 and G.707-compliant EOS (Ethernet Over SDH) technology and VLAN technology, each Ethernet port can employs 1~4 separate Virtual Concatenation Groups (VCG), and each VCG can be assigned to one or more Ethernet ports. The bandwidth of VCG can be flexibly configured for efficient transmission of Ethernet data over SDH network.

AN-STM-1-ETH supports NE management based on CLI command and SmartView network management platform based on SNMP_V1 and SNMP_V2 protocol, to perform excellent management such as configurations, alarm monitoring and performance statistic.

AN-STM-1-ETH is suitable for data access network on the client side. With the technology compliant to ITU-T standards, it can communicate with products from other vendors adopting the same standards.
