7.7.4 Specifications
The following table lists the specifications of the Telco 64 subscriber cables.
7.8 Fiber Cable
Fiber optic cable connects the management card to the upstream device.
7.8.1 Application
The fiber optic cable carries optical signals. The connections are as follows:
• One end of the fiber optic cable connects to the transceiver in the management card’s SFP slot.
• The other end of the fiber optic cable connects to a peer Gigabit Ethernet device.
7.8.1.1 Connection to the Gigabit Ethernet Backbone Network
The IES with MSC1002G delivers services originating from an active Gigabit Ethernet network.
Duplex optical fiber cable with LC (Lucent Connector) connectors or copper Ethernet cable carries
upstream and downstream traffic between the MSC1002G card and the active Gigabit Ethernet
network. MSC1002G converts the downstream traffic from the signal sent by the peer Gigabit
Ethernet device to the required service format for delivery to the subscriber. MSC1002G also
converts the upstream traffic back to an optical or electronic signal for transport over the Gigabit
Ethernet network.
The SFP slots have priority over the Gigabit ports. This means that if a SFP transceiver and the
corresponding Gigabit port are connected at the same time, the Gigabit port will be disabled.
7.8.1.1.1 Appearance
The following figure shows a duplex fiber optic cable with LC connectors.
