Transition Networks Enables Fiber-to-Fiber Network Extension

  • Transition Networks
MINNEAPOLIS, MN — Transition Networks, a provider of innovative, high-value, data network integration solutions, announced its ION 10 Gigabit Ethernet remotely managed media and rate converter network interface device (NID) (C4221-4848), the first 10 Gbps Ethernet fiber-to-fiber extender on the market that provides bandwidth rate limiting from 1Gbps to 10Gbps and in-band management of both the local card and a remotely located card.

By using the C4221-4848 in an ION chassis at a customer’s site, the service provider is able to establish a demarcation point between their network and the customer’s network, to easily manage that link from the same card in a Central Office and provide the customer with a reliable service and consistent up-time.

The device has two 10GBase-x (SFP+) ports and a 10/100/1000Base-T copper port, which can be used to integrate legacy 10/100/1000 Ethernet devices to a 10 Gig Ethernet link. The C4221 supports 100FX, 1000X, SGMII, and 10 Gig SFP modules, which provides flexibility when connecting legacy devices to 10Gig Ethernet backbones. Remote management is possible when two C4221 are linked together over fiber and one card is installed in a managed chassis while the other is installed in an unmanaged chassis.

The C4221 supports bandwidth allocation, allowing service providers to deliver the amount of bandwidth that is contracted with the customer. Service providers are able to deliver tiered Ethernet bandwidth services from 1Gbps to 10Gbps to their business customers with end-to-end visibility of the link status, and complete management control of the devices’ configuration.

Remote Control Device Management to Customer Premise
“The ability to remotely extend device management to the customer premise makes it possible for service providers to have the level of control they need for delivering Business Ethernet services,” said Curt Carlson, product manager with Transition Networks. “The C4221 is a more cost effective solution than higher density Carrier Ethernet grade switches that include unnecessary features and cost for a customer demarcation device.”

The C4221 can also be used by enterprises to create a 10 Gig Ethernet backbone link between buildings in a large corporate campus or a college/university campus and when used as a signal regeneration device, the C4221 can be used to extend 10 Gigabit Ethernet service over existing or legacy fiber infrastructure.

The NID can be used in a Transition Networks managed ION 19-slot chassis, the managed 6-slot chassis or in the in an unmanaged 1-slot chassis.
