12X 10G/3X 40G LAN/WAN/OTN FRAMER/MAPPER/PHY FOR
CARRIER ETHERNET OPTICAL TRANSPORT
Overview
Highlights
• Lowest power and smallest LAN/
WAN/OTN Framer/Mapper/PHY
device for high-density 10G/40G
carrier Ethernet optical transport over Ethernet LAN, WAN, or
Optical Transport Network
(OTN) standard.
• Comprehensive application coverage: The BCM84512 incorporates LAN/WAN conversion, all
10GbE-to-OTN mapping modes,
and various FEC codes to enable
interoperability between different network operators and system equipment vendors.
• Unprecedented level of mixedsignal integration: The
BCM84512 successfully integrates high-speed PHY/EDC,
clock synthesis, and jitter-filtering functions with complex digital processing of Ethernet LAN,
WIS, and OTN protocols.

Carrier
Ethernet
To reduce board design complexity and enable lower
power and cost savings, the BCM84512 integrates
fractional-N clock synthesizers, as well as ultralow
bandwidth jitter filtering PLLs commonly available
today as discrete components. Only a single
156.25 MHz reference clock is required for either
LAN, WAN, or OTN operation.

Supported
The Broadcom BCM84512 is a highly integrated, ultralow-power, 12-port 10G, or a 3-port 40G, OTN
Framer/Mapper/PHY device. The BCM84512 incorporates OTN mapping/demapping, framing/deframing,
and forward error correction (FEC) encoding/decoding functions to enable high-density and low-power
packet optical transport applications.
The BCM84512 is built upon Broadcom's field-proven
10G/40G Ethernet (10GbE/40GbE) PHY/EDC products
with the additions of 10GbE/40GbE performance
monitoring and all functions required to transport
10GbE/40GbE over LAN/WAN/OTN networks. With all
the OTN functions disabled by software, the
BCM84512 is a LAN/WAN PHY with advanced Electronic Dispersion Compensation (EDC), targeted for
SMF application that interface to either SFP+ or XFP
modules. With OTN functions enabled by software,
the device enables an Ethernet-based line card to
interface to an OTN network without the need for an
extra transponder card. With these functions
enabled, the device also provides longer transmission
distance and robust OAM support per the ITU-T G.709
OTN standard.
To ensure interoperability with the existing 10G/40G
OTN deployments, the BCM84512 integrates the standard RS(255,239) FEC code and enhanced FEC codes
as specified in ITU-T G.709/G.975. In addition, the
device incorporates performance monitoring and
failure handling for 10GbE LAN, WIS, and OTN,
according to the respective standards.
