Description

The BCM8228 is a highly integrated, low-power, variable-rate transceiver/mapper device that lowers the cost of data communication (datacom), telecommunication (telecom) and storage services while providing fast upgrades and provisioning of these services. With the new Broadcom BCM8228 VariRate device, system Original Equipment Manufacturers (OEMs) can now develop single linecard solutions that feature a host of transmission protocols and speeds from the same physical link.

The BCM8228 provides interfaces at data rates ranging from 155 Megabits per second (Mbps) up through 2.666 Gigabits per second (Gbps). The services supported by the BCM8228 include telecom services at OC-3 (155-Mbps), OC-12 (622-Mbps) and OC-48 (2.5-Gbps); datacom services at Gigabit Ethernet (1-Gbps); and Storage Area Network (SAN) Fibre Channel services (1- and 2-Gbps).

With the new all-in-one BCM8228, service providers will be able to provide new services or upgrade existing services from a single linecard and can reduce their operational expenses by eliminating the need to maintain an inventory of multiple linecards for each protocol and data rate. Maintenance costs will also be lowered since all of the protocols reside within a single card versus multiple cards, reducing the amount of resources and hardware required of BCM8228 to maintain the services.
