Broadcom Delivers Industry’s First Dual 400G MACSec PHY for Hyper-scale Data Center and Cloud Infrastructure
September 23 2019 - 4:00AM
Broadcom Inc. (NASDAQ: AVGO) today announced commercial
availability of its BCM81343 device, a dual 400G MACSec PHY with
AES-256, designed to address security requirements for high speed
interconnects in modern network infrastructure including
hyper-scale, cloud, service provider and enterprise networks.
Expanding upon the previous generation dual 100G MACSec PHY, the
BCM81343 quadruples the switch bandwidth capability with dual 400G
ports and supports the IEEE 1588 precision time protocol (PTP)
providing accurate clock timing for time-sensitive transactions and
mission-critical tasks.
Cloud and service provider networks are rapidly transitioning to
400G Ethernet to support increasing bandwidth demands and emerging
5G services. A wide range of cloud & 5G applications need
hardware-based MACSec capability to secure high speed data links
and accurate time-stamping to ensure high reliability and quality
of service. Broadcom’s BCM81343 is the industry’s first dual 400G
MACSec PHY device enabling cloud and service providers to maximize
the port throughput of the latest 12.8-Tb/s switches such as
Broadcom’s Tomahawk® 3, Jericho 2 and Trident 4. The BCM81343 helps
secure high-speed data links between servers, switches and routers
while providing accurate PTP time-stamping needed for 5G
services.
BCM81343 Product Highlights
- Dual 400GbE PHY supporting CDAUI8, CDAUI4 electrical interfaces
for QSFP-DD & OSFP optical modules
- Supports MACSec in applications from 10G to 400G
- Support MACSec in both 400G retiming & 400G<->100G
(reverse gearbox) applications
- IEEE 802.1AE 256-bit MACSec supporting data rates from 10G to
400G
- IEEE 1588 supporting up to Class-C to meet stringent 5G timing
requirements
- Proven interoperability with Broadcom switch ASICs and ASSPs
using 28-Gbaud PAM-4 and NRZ SerDes
- Pin-compatible to Broadcom’s standard 400G reverse gearbox and
retimer devices for easy upgrade
- Low power 16nm CMOS technology
“Data privacy and security have become critical in the data
center and cloud infrastructure given the increasing number of
security breaches. As cloud and service providers
transition their networks to 400G Ethernet to support the
growing demand for higher bandwidth and emerging 5G services,
it’s imperative that their 400G networks be equipped with 400G
MACSec to protect against intrusion attacks, wiretapping and other
threats,” said Lorenzo Longo, senior vice president and general
manager of the Physical Layer Products Division at Broadcom.
“Expanding upon Broadcom’s industry-leading 400G PAM-4
PHY portfolio, the BCM81343 is the first commercial 400G
MACSec PHY that delivers up to 800G of switch bandwidth with
PTP time-stamping for 5G applications.”
"As 400GbE deployments are ramping in hyper-scale data centers,
it's vital that MACSec be scaled to 400G to protect data-center
interconnects. With its shipment of 400G MACSec PHYs, Broadcom
is building on its optical PHY leadership and accelerating the
transition to 400G Ethernet,” said Bob Wheeler, principal analyst
with The Linley Group.
