    Carriers Select a connectivity provider. The access points that you can choose vary based on the connectivity provider.
    Note
    • If you choose China Unicom, China Telecom, or China Mobile as the connectivity provider, you can lease lines only from the selected connectivity provider. You are not allowed to lease lines from other connectivity providers.
    • If you choose China Unicom, China Telecom, or China Mobile as the connectivity provider, bare fiber is not supported. You must lease lines from these connectivity providers.
    Access Point Select an access point that is closest to your data center.

    Access points are Alibaba Cloud data centers located in different regions and support different ports. Each region contains one or more access points. For more information, see Locations of access points.

    Understand Billing Rules Read the billing rules and click Yes. For more information about the billing, see Billing.
    Port Specification You are charged a resource usage fee based on the port specification. We recommend that you select a port specification based on your business requirements. To upgrade the maximum bandwidth of an Express Connect circuit from 500 Mbit/s to 2 Gbit/s, contact your connectivity provider. Then, contact the sales manager from Alibaba Cloud to replace the optical transceiver module.
    • To apply for an Express Connect circuit whose maximum bandwidth is no greater than 1 Gbit/s, select 1G and below.
    • To apply for an Express Connect circuit whose maximum bandwidth is greater than 1 Gbit/s, select 10G.
    Note If you want to purchase 40 Gbit/s and 100 Gbit/s ports, Submit a ticket.
    Port Type You can use a copper Ethernet port or an optical port.
    • The switches in the access points of Alibaba Cloud support RJ-45 copper Ethernet ports. The default port specification is 10 GE. 100BASE-T and 1000BASE-T copper Ethernet ports are also supported. The port rate depends on the port specification.
    • Optical ports are known as bare optical fibers. Network carriers use optical cables of the transmission network to connect to Alibaba Cloud. The rate of an optical port depends on the negotiated speed of the optical transceiver module. The port rate can be 1 Gbit/s, 10 Gbit/s, 40 Gbit/s, or 100 Gbit/s.
    Note
    • Different access points provide different port specifications. We recommend you check the port specifications available for purchase before you apply for an Express Connect circuit.
    • By default, Alibaba Cloud provides optical transceiver modules with 1 Gbit/s and 10 Gbit/s ports. This type of optical transceiver module supports a maximum transmission distance of 10 km.

      If you want to use optical transceiver modules with 40 Gbit/s and 100 Gbit/s ports or optical transceiver modules that support a maximum transmission distance of greater than 10 km, purchase them from a third party. If you purchase an optical transceiver module from a third party, you must contact your customer business manager from Alibaba Cloud before you install the Express Connect circuit in the Alibaba Cloud data center.

    • To use optical ports, make sure that the connectivity provider uses optical fiber cables to connect to the access device of Alibaba Cloud.
    • Alibaba Cloud does not host fiber optical transceivers for customers. Therefore, make sure that the connectivity provider uses the supported type of cable to connect to the access device of Alibaba Cloud.
    Redundant Connection ID Specify a redundant Express Connect circuit in the same region to configure equal-cost multi-path (ECMP) routing.
    • If the Express Connect circuits are connected to different access points, you do not need to specify the redundant Express Connect circuit.
    • If the Express Connect circuits are connected to the same access point, you must specify one of them as the redundant Express Connect circuit. The Express Connect circuits connected to the same access point are allocated to different access devices.
