With the widespread availability of switch chips featuring flexible, multi-speed port interfaces supporting 10G, 40G, 100G, and emerging Ethernet speeds, PHY transmission box solutions are needed to ensure robust signal integrity and optimize port adaptation. Broadcom's latest PHY transmission boxes extend switch capabilities by providing flexible port interfaces and maximizing the electrical link-to-optical interface distance with minimal power consumption. The BCM82793 and BCM82332 are application-optimized, cost-effective 100G devices that support IEEE 802.3bj clause 73 auto-negotiation, FEC clause 91, and transmission training clauses 92 and 93.
Key features
BCM82332 -- 10G/40G/100G Tri-PHY
• Supports 100G 10:4 transmission box mode and multiple re-timer modes including 12x10G Ethernet and 3x40G Ethernet
• Optimized for enterprise-class switches employing a mix of 10GbE, 40GbE, and 100GbE ports.
BCM82793 -- PHY 100G Transmission Box
• Supports 100G 10:4 transmission box mode and multiple re-timer modes, including 2x40G Ethernet and 10x10G Ethernet.
• Footprint compatible with industry standard 100G PHY transmission box
BCM82864 -- 40G Quad-PHY Transmission Box
• Supports 160G 16:8 transmission box mode for 40G Ethernet and multiple re-timer modes including 2x100G Ethernet and 2x40G Ethernet
• 100G Ethernet bypass allows the user to change the front panel ports from 40G to 100G simply by swapping two 40G QSFP+ modules for one 100G QSFP28 module
• Enables 64×40G Ethernet switch arrays in hyperscale data center applications.
“Broadcom has consistently offered transmission boxes that meet a range of multiplexing options,” commented Loring Wirbel, senior analyst with The Linley Group. “By supporting unique re-timer modes such as 12x10 and 3x40, and by supporting 802.3bj clause 73, Broadcom continues its leadership in providing ideal PHY solutions for data centers.”
“Broadcom is the undisputed leader in high-speed Ethernet PHY solutions for network infrastructure, with over 100 million 10G ports shipped to date. Broadcom has developed a comprehensive PHY product portfolio that connects the latest switch chips to a wide range of pluggable optical transceivers. The latest addition to our PHY transmission box offering further extends Broadcom’s leadership in optical PHYs to data center and enterprise networking applications,” said Lorenzo Longo, senior vice president and general manager of the Physical Layer Products Division at Broadcom.
