SEPTEMBER 22, 2009 -- Access technology provider Calix has expanded its lineup of optical network terminals (ONTs), each optimized for unique service-provider deployment scenarios. The complete Calix ONT portfolio will be on display at the Calix booth (#501) at the 2009 Fiber to the Home Council Conference and Expo in Houston, TX, Sept. 28-30, 2009.

New applications such as mobile backhaul, multidwelling unit (MDU) services, and small and medium-sized business (SMB) deployments are emerging as large revenue opportunities that often complement residential fiber access networks. Each application requires a different set of ONT form factors and features.

"These 15 new ONTs provide our customers with unparalleled flexibility in deploying fiber access networks," says Kevin Pope, senior vice president of product development. "As the demand for bandwidth continues to grow in both residential and business environments, and as service providers seek new opportunities to capitalize on their fiber infrastructure, specialized applications like mobile backhaul become critical to meeting community requirements as well as enhancing the fiber access business case. Our extensive portfolio of ONTs means that service providers seeking to address these requirements aren't trying to fit a square peg in a round hole -- they are leveraging the optimal form factor and feature set to meet the real requirements for any deployment scenario."

Each of the 15 ONTs is optimized for one of four applications:
Mobile backhaul - Designed to meet the strict performance criteria imposed by mobile service providers.

  • 766GX/766GX-R/766GX-R24 (eight T1s [TDM or pseudowire]), four GE, eight POTS, available in wall- and rack-mounted versions, +24-V and -48-V options)


MDU services - Broad feature set designed for residential deployment of four and eight living units and featuring what the ocmpany says is the first MDU ONT in the industry with an embedded and managed RF return for two-way RF video.

  • 760GX and 762GX (four to eight GE, eight POTS, four RF ports up to 1 GHz)
  • 763GX/763GX-R (eight GE, eight POTS, eight RF ports up to 1 GHz, integrated SCTE RFOG micronode)


Small and medium-sized businesses - Optimized for the wide deployment requirements of business parks, strip malls, and office buildings.

  • 765G-R/765G-R24 (four T1s, four GE, eight POTS, available in wall- and rack- mounted versions, +24-V and -48-V options)
  • 767GX-R rack-mounted design for mixed residential and business environments that require support of T1s and two-way RF video (8 T1s [TDM or pseudowire], four GE, eight POTS, eight RF ports up to 1 GHz, integrated SCTE RFOG micronode)


Single-family residential - A variety of new units supporting 1-GHz RF video.

  • 720GX, 721GX, 722GX, 724GX (1 GE, 1 FE, two to four POTS, RF port up to 1 GHz, HPNA support on some models)
  • 725GX, includes an embedded and managed SCTE RFoG micronode (1 GE, 1 FE, two to four POTS, RF port up to 1 GHz, integrated SCTE RFOG support)


The ONT acts as the interface to the subscriber and defines what revenue-generating services can be offered to subscribers today and in the future. Calix says the ONT also accounts for more than two-thirds of a service provider's electronics costs for fiber access equipment, factoring heavily in the initial business case, as well as in the ongoing economic viability of a fiber access deployment. For these reasons, ONTs and the outside-plant fiber infrastructure should be the most futureproof parts of a fiber access network, says the company.

The Calix 700GX family of ONTs support both GPON and active Ethernet in one ONT. This autodetect technology allows service providers to switch from one technology to the other without a truck roll. The ONTs also feature remote provisioning that reduces the cost to install and turn up a new ONT. All versions offer a 10/100/1000 Ethernet port into the home to futureproof the ONT. An intelligent Ethernet interface supports multiple VLANs and multiple types of services over a single interface in the home, simplifying wiring in the home. All Calix ONTs support standards-based extended-reach GPON, which doubles the traditional reach of GPON-delivered services out to 40 km and increases addressable serving areas up to 4x. Each ONT is managed by the Calix Management System (CMS), which provides a single network view and a common user experience independent of media type, protocol, or service.
