Yesterday, at the Interop show in Las Vegas, Broadcom introduced its BCM8228 variable-rate transceiver/mapper device that allows OEMs to develop single linecard solutions that feature a number of transmission protocols and speeds from the same physical link.
The BCM8228 provides interfaces at data rates ranging from 155 Megabits/sec (Mbps) up through 2.666 Gigabits/sec (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 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 to maintain the services.
The BCM8228 device can be deployed in a range of equipment for Metropolitan Area Networks (MANs) and Wide Area Networks (WANs) including routers, switches and SONET/SDH systems. Due to its multi-protocol capabilities, the BCM8228 is also suited for Multi-Service Provisioning and Switching Platforms, the latest generation of SONET/SDH equipment.
Samples of the device are currently available at a unit price of $150 per 1,000 units. Broadcom also offers an evaluation kit including reference designs, evaluation boards, GUI-based software and documentation.
