Alloptic announces deep fiber solution

Alloptic at last week's National Fiber Optic Engineers Conference announced the availability of its curbG.E.A.R. (Gigabit Ethernet Access Router) Optical Networking Unit, a device that lets network providers deliver high-bandwidth fully converged services to residential communities, multidwelling units and multi-tenant units.

Alloptic's curbG.E.A.R. is a modular unit that provides a 1.25G bit/sec symmetrical Ethernet line rate over a fiber link. It can either be placed in a hardened outside plant or on the customer premises.

According to Alloptic, curbG.E.A.R. delivers toll-quality time-division multiplexed voice or voice-over-IP, as well as broadcast and on-demand video, in addition to gigabit data services. Alloptic says it allows carriers to tailor services via bandwidth shaping, which is the modifying of signals between networks for interface purposes. Bandwidth shaping also lets them offer guaranteed service-level agreements, the company said.

The ONU can be deployed in tree, ring, star, bus and point-to-point topologies, and supports plain old telephone service (POTS), T-1, 10/100 BaseT Ethernet, IP multicast and dedicated wavelength services. CurbG.E.A.R. features four 10/100 BaseT and two T-1 card slots, and has four optional slots for additional 10/100 BaseT, T-1 or POTS line cards.

The unit measures 10 inches in height, 10.5 inches deep and 20 inches wide, and uses 50 watts of power. The curbG.E.A.R. has hot swappable plug-in cards and supports remote software upgrades and port activiation.

Other features include quality-of-service provisioning, packet classification and filtering, and prioritization based on Layer 2 and 3 information. The hardened unit was designed to withstand extreme environmental conditions including temperature changes from -40 degrees Celsius to +80 degrees Celsius.

Alloptic is the first to offer such a device supporting 1.25G bit/sec symmetrical line speeds. Quantum Bridge released a similar product, the QB600, with the same basic capabilities but offering only 622M bit/sec symmetrical line rates. Terawave also offers a similar product, the TW150RT, that operates at 622M bit/sec symmetrically. All three products tout the ability to back-haul services from remote DSL access muxes (DSLAMS), thereby eliminating the 18,000-foot distance limitation of central office-served DSL services.

Alloptic says curbG.E.A.R. costs about US$6,500. The company plans to announce fiber-to-the-curb customer trials later this year.
