Fancy 10 Gbps home broadband? Broadcom's built the guts of it

SoC is compatible with cable's DOCSIS and emerging EPON fibre standards

By Richard Chirgwin, 6 Aug 2015

While network operators around the world squeeze the last drops of sweat out of their copper, silicon vendors like Broadcom have an eye firmly on a fibre future.

The company, currently in the throes of a takeover by Avago technologies, has announced a reference design to help its OEMs build kit to the emerging Ethernet Passive Optical Networks (EPON) standard, CableLabs' contribution (via the IEEE) to the eventual migration to fibre-to-the-premises.

So as not to demand a forklift migration at the network's head-end, CableLabs' Ethernet PON and DPoE (DOCSIS Provisioning of EPON) is designed to format existing DOCSIS transmissions over all-optical networks.

The Broadcom reference design shows OEMs how to create DOCSIS-compatible residential EPON gateways capable of 10 Gbps.

Based on the company's BCM55030 system-on-a-chip, the gateway implements video-on-demand, HD IPTV, and VoIP over high-speed broadband networks. DPoE 2.0 compliance gives the gateway the look and feel of a DOCSIS gateway so operators can connect all-fibre networks without having to upgrade their current core network infrastructure.

The BCM55030 chip includes a 10 Gbps media access controller, 10 Gbps serialisation/deserialisation with forward error correction, and a four-port gigabit Ethernet switch.

The chip adds all-optical capabilities to Broadcom's existing BCM33843 DOCSIS gateway, which handles the audio-video and cable broadband services, full-band-capture remote tuning, and remote diagnostics.

The company last week reported second quarter results that must have pleased Avago: revenue grew in the high-end smartphone, broadband access, and networking markets.

That gave it revenue of US$2.1bn (AU$2.8bn) for Q2 2015, 2.7 per cent up on Q2 2014, and GAPP net income of US$386m (AU$525m) for the quarter compared to Q2 2014's loss of US$1m (AU$1.3m). ®
