Broadcom Enters FTTH Chipset Market

Broadcom is entering the PON chip market and has secured design wins with a major tier-1 equipment vendor. While this is something predicted here, the timetable was sooner than expected. This will have a substantial impact on FTTH component and equipment suppliers as well as the carrier currently conducting lab trials with the device.

Discussion with a number of industry participants revealed an unannounced Broadcom GPON program in advanced stages of development, with a design win at Alcatel-Lucent, the upcoming primary supplier of Verizon’s FiOS hardware as the carrier transitions away from BPON.

Broadcom designed the device internally despite a lack of active involvement in FSAN, the carrier-run group responsible for GPON interoperability that leads the ITU standards body. The device was first prototyped in an FPGA and the company now has silicon samples destined for testing in Alcatel equipment as well as Verizon carrier labs. Target deployment is 2H2009.

The chip includes the MOCA transceiver (revision 1.1) functions required by Verizon and currently supplied by Entropic in a standalone device. Broadcom is not doing the central office (OLT) chip and is initially focusing on a highly integrated gateway device for the customer location that displaces the standalone router and optical ONU terminal.

This is not unlike similar Broadcom products made for the Cable Modem and DSL markets. As cable/DSL broadband growth slows it is no great surprise that it plans to enter the FTTH chipset market. Broadcom and Broadlight, a private chip company which makes BPON and GPON FTTH chipsets, partnered in June 2004 to deliver FTTH chipsets (press release here). This partnership failed to reach any public fruition.

The PON chipset market reached $100M in 2007 but hasn’t reached the growth rates many hoped for. It is clear that Broadcom made the decision to enter this market not for the $100M market size, but for the opportunity to seize the MOCA market and continue to position itself as the chipset supplier for the connected home.

For a discussion of the difference between GE-PON and GPON see here.

Impact on GPON Chipset Vendors

image While GPON attracts a great deal of attention it accounted for only 18% of ports shipped in Q108, as deployments on the scale of Asia’s (GE-PON – 60% share) have yet to begin worldwide (source Dittberner Associates). As written before, we staunchly believe the majority of the market for the next 5 years will be GE-PON, due to its dominance of Asian deployments. While the GPON market is smaller Alcatel-Lucent is the lead vendor for Verizon, which is the largest planned GPON deployment.

  • Freescale was the incumbent supplier of GPON silicon to Alcatel-Lucent (press release here) and according to checks has been displaced from future designs. It is possible that Freescale is exiting the GPON business as a result of being displaced by Broadcom.
  • Broadlight was a successful vendor of BPON (standard previous to GPON) chips to Tellabs and encountered much stiffer competition in the GPON marketplace. Broadlight continues to make forward progress with a GPON design win at Huawei, which is making inroads in the EMEA region. At this point Huawei and Alcatel/Lucent account for most global GPON shipments.
  • PMC-Sierra, while a market leader in GE-PON based FTTH chipsets, has not made significant inroads in the GPON marketplace. The emergence of Broadcom in a critical tier-1 account will make it difficult if not impossible for PMC to reach the level of dominance in GPON that it currently has in GE-PON.
  • Ikanos occupies a niche within the GPON hierarchy, focusing on hybrid VDSL/FTTH applications that leverage its VDSL expertise. Ikanos also has a moderately successful home gateway chipset (acquired from Analog Devices) that gives it the ability to produce a full GPON system on a chip for the ONU. It also can mimic the features of a comparable VDSL gateway. Broadcom also has VDSL technology, essentially negating any technology advantage Ikanos had.
  • Several other vendors such as Conexant and Iamba face yet another competitor.

One can make a solid case that Alcatel-Lucent and Huawei and perhaps Motorola are the only high volume GPON suppliers for the foreseeable future. The win by Broadcom locks up a significant portion of this future market share and will make it difficult for other vendors to reach a dominant position in GPON in the same way PMC-Sierra did in GE-PON. Broadlight appears to be the only viable competitor to Broadcom at this point

Impact on GE-PON Chipset Vendors

We have no information that Broadcom is making a GE-PON device but given its strength in access chips and its efforts in GPON, it is hard to imagine something isn’t in the works. GE-PON accounts for the majority of the market and is closer to moving to a “White Box” model, where equipment design and manufacture is outsourced to Chinese and Taiwanese ODMs. This is how Cisco/Linksys, Logitech, and Netgear get the hardware to sell to consumers. Broadcom excels at this market and has the size and experience to dominate it.

The GE-PON chipset market is more mature, with nearly most chips being supplied by PMC-Sierra and the rest by Teknovus. PMC-Sierra dominates Japan but Teknovus has secured significant share in China.

We’ve speculated in the past (see Teknovus and Passave at a Crossroads) that Broadcom would enter this market. If China continues its trend towards deploying GE-PON it is a certainty.

Impact on MOCA chip Vendors

While GPON chipset market is (was) fragmented there is only one dominant MOCA chipset vendor – Entropic.

Entropic recognized a whopping 75% of their revenue from Verizon FiOS suppliers in Q108, or about $31.5M in quarterly revenue. Entropic provides the MOCA chipsets in equipment used by Verizon as part of it’s FiOS deployment. These chipsets enable the Verizon set-top boxes made by Motorola to communicate with the FiOS FTTH gateway (Tellabs) or home router (Actiontec) over existing in-home coaxial cable. In some cases the set-top boxes connect to the standalone home router, in newer configurations its functions are collapsed into the optical gateway itself.

As Verizon transitions from BPON to GPON the Tellabs FTTH gateway business will transition to Alcatel/Lucent. This is the design Broadcom has secured.

Broadcom’s new GPON chip includes the MOCA transceiver, using technology acquired from Octalica (see Press Release), which eliminates the need for a standalone MOCA device in the FiOS FTTH gateway or a separate chip in the Actiontec router. This is the chip currently supplied by Entropic.

Entropic recognized 39% of their revenue from Actiontec (26%) and Tellabs (13%) i
n Q108. The loss of these sockets as a result of the availability and deployment of an integrated Broadcom device would have a dramatic impact on Entropic’s revenue.

Another 36% of Entropic’s revenue during Q108 was from Motorola. While the Broadcom GPON chip is not a replacement for Entropic’s Verizon/Motorola set-top box application, Verizon will qualify Broadcom’s MOCA technology in their labs prior to deploying the new Alcatel FTTH gateway equipment. Once Broadcom’s Octalica-based technology is qualified in the gateway, it becomes a viable supplier of standalone MOCA chipsets for the Motorola set-top box. At best this would have a downward impact on pricing, at worst Entropic could lose the design.

Broadcom is already a major supplier of silicon to set-top box equipment makers such as Motorola. They supply much of the bill of materials for these systems and can use kit pricing to squeeze other vendors out. Broadcom also has the intellectual property to integrate the MOCA technology into set-top box system-on-a-chips, similar to what they have done with their GPON chip.

Based on Entropic’s Q108 customer profile, 75% of their revenue is immediately at risk once Broadcom’s GPON/MOCA device is qualified at Verizon.

Summary

While the arrival of Broadcom as a GPON supplier is certainly news and will change the lines of force within GPON chipset, it is Entropic that stands to be impacted most. Broadcom will leverage it’s GPON win to dominate the nascent MOCA market. While a single GPON chipset might fetch $20 or so and will generate $40-60M a year in revenue, Broadcom is using this as an entry point to address the larger MOCA opportunity of $125M (and growing 50% a year) currently owned by Entropic.

The larger goal is to seize control of the nascent home networking market. The PON ONU, DSL Gateway, or Cable Modem represents the commanding heights. Broadcom wants to make sure they control the silicon in the set-top box and the Cable/DSL/FTTH gateway because that it the surest way to control the silicon in the myriad number of devices that will appear in the connected home in the next decade.

Discussion

Comments are disallowed for this post.

  1. BRCM entering the MoCA market is definitely a testament of the importance of this market.

    BRCM did not go into MoCA believing that VZ will be the only deployment. So this means that the market can grow significantly.

    Any announcement from a Cable company to use MoCA will be a huge uptake for ENTR.

    Lets say the market for MoCA will reach 500 600Mil in a couple of years, I do not expect to see ENTR market share to drop below 50% in the same timetable.

    This makes ENTR undervalued.

    If MoCA reamins relegated to VZ, BRCM will probably slow down investment in that area and develop anything that will become the Home Networking Ubiquitous standard.

    I think that ENTR has already priced in the BRCM monster coming.

  2. MoCA is just getting in the Market:

    And ENTR has the early lead.

    D-Link introduces DXN-221 Coax Ethernet Adapter Kit
    by Darren Murph, posted May 28th 2008 at 9:56AM

    D-Link’s no stranger to HD streaming, and the outfit is proving that it’s still got game by announcing the Coax Ethernet Adapter Kit. The Multimedia over Coax Alliance (MoCA)-certified package consists of two DXN-220 adapters, each of which boast coaxial F-type connectors and an Ethernet port meant to give internet / network access to various rooms without worry over wireless connections flaking out on you. As you can tell, this one was designed to expand home networks without requiring any additional wiring (if you’re pre-wired for cable, that is), and being that it operates in the 800MHz to 1,500MHz range, there won’t be any interference with cable TV transmissions or the like. The DXN-221 kit — which includes a pair of the aforementioned adapters — will be available in Q3 for $199.99, while individual adapters can be purchased for $109.99 apiece.

  3. The problem with MOCA is that it is a one trick pony, i.e., it has been adopted by VZ only. All other telcos are showing interest in HPNA and Homeplug. Looking forward, ITU-T is working on a home networking standard that will incorporate HomePlug and HPNA and will be able to operate (albeit with different PHYs) on cable, phone wires and power lines. Once this standard is ratified, we can expect additional Si vendors to join the fray.
    A major problem faced by MOCA is that it is a coax oriented solution and in most markets – other than the US – homes are not wired with coax.

  4. Very interesting andrew…nice story break.

    A thought that comes to mind immediately is the future of wireless inside the home network.

    One of the main reasons for using MoCa has been the poor QoS of wireless for video streaming…Ruckus and a few others seem to have a solution that doesn’t have big-arrier traction…but the inevitability of wireless continues to talked about mainly due to convenience…how many people really use a cabled home network with all bells/whistles?

    I wonder if this means now more control over home wireless for BRCM and next gen wireless technology – this will be an interesting area to watch since Moca is useful mainly here in NA with legacy cabling.

    btw – MoCa is under a RAND license from ENTR, so I suspect they will get some upside from this.

  5. Outstanding move by Broadcom and people may want to disagree but Entropic will have a rough time in the MoCA market and is going to sink soon. It is irrelevant whether MoCA grows or not, as Bcom has better silicon resources, and complete solution for verizon.

    I agree ENTR will loose a lot of revenue.
