The Fiber Distribution System (FDS) provides an integrated central office (CO) fiber frame system for FTTX deployments using a “homerun” PON methodology. This configuration allows service providers to optimally deploy into environments where the number of desired homes can all be effectively reached from the CO over a 1×32, 1×16, or 1×8 signal strength; placement of OSP cabinets is not desirable; OSP cabinets are used only as crossconnects; or control and administration of optical components is desired back in the CO. Utilizing the company’s high-density panels and optical component chassis loaded with WDM modules and 1×32 modules, up to 576 customers can be served in a standard 7-ft frame. The FTTX FDS is designed for 23-inch frame environments. Other configurations are available with an accompanying line of fiber management accessories.APA Cables & Networks,www.apacn.com
A customer premises device, the FNT3012 media converter offers full-duplex 100-Mbit capability over a single fiber, streamlining fiber counts and fiber management and reducing installation costs. It features a robust optical loss budget (0 to 16 dB), standard SC connector port, loop-back test function, autonegotiation, integrated fiber management, SNMP traps, and a desktop or wall-mount design in a 105×130×35-mm area. Supported interfaces include 10/100Base-TX, TTC TS-1000 Class-S, and 100Base-FX.

The latest addition to the LightningEdge line of access devices, the LE-135 enables deployment of true Carrier Ethernet services to both business and residential subscribers in the multitenant-unit and multidwelling-unit markets. The dual-module design allows central configuration, which enables reuse of existing wiring for analog phone, voice, video, and data. Switching features such as inquisitive leave enable multiple video set-top boxes off a single 10/100-Mbit/sec port. Field upgradeable/replaceable units reduce downtime and service provider inventory costs. All ports are dual-speed, either 10/100-Mbit/sec or Fast/ Gigabit Ethernet, for the delivery of subscriber drops over fiber or copper. Ring architecture supported by Rapid Spanning Tree Protocol and Rapid Spanning Tree Domains features SONET-like resiliency and stability.

The Calix E5, the first platform in the E-Series line of IP service edge nodes (SENs), aids service providers by reducing subscriber loop lengths. The node eliminates the need for service area interface (SAI) crossconnect upgrades, fits within existing right-of-ways, includes managed remote powering options, and converts POTS to VoIP, thereby reducing installed capex by more than 50%. With up to 16 Gigabit Ethernet uplinks, the E5 is designed to support a smooth transition to FTTP builds as well as FTTN access networks. The E5 can terminate POTS at the SAI. In this “DSL+POTS combo” model, service providers can simplify physical connectivity at the crossconnect and optionally retire the upstream feeder portion of the copper plant. In this configuration, the node converts POTS to VoIP using SIP or H.248 signaling for transport over Gigabit Ethernet along with data and IPTV services. At the central office, the voice services can be converted back into a GR-303 TDM voice format or handed off to the network as VoIP, thus speeding the migration to an operationally efficient all-packet network.

The BLC 6314 10-Gbit Ethernet transport and optical line termination (OLT) blade adds dual 10-Gbit optical Ethernet and multiple 1-Gbit Ethernet interfaces to the BLC 6000 broadband loop carrier system, providing symmetrical bandwidth that enables high-capacity access networks with 10-Gbit Ethernet resilient transport rings at a lower cost than SONET-based OC-192. The blade is a high-performance Ethernet switch with two 10-Gbit/sec Ethernet small-form-factor pluggable (SFP) optical subscriber ports to provide the BLC 6000 with direct active fiber subscriber access distribution. Two 10-Gbit Ethernet intelligent blade interconnect architecture copper ports provide the flexibility to economically deploy the system in low-, medium-, or high-density applications. The blade also includes 16 Gigabit Ethernet ports that, when populated with SFP lasers, support optical subscriber drops for homes or businesses.

A full L-band version of the PowerReach tunable transponder extends the flexibility of dynamically tunable transmitters across the entire DWDM band and offers high optical-signal-to-noise-ratio (OSNR) performance. The transponder provides wavelength tunability from 1,570 to 1,607 nm with ±25-pm accuracy and features a chromatic dispersion window of 2,000 psec/nm, beyond the industry standard of 1,600 psec/nm, permitting longer-reach transmissions. It has a power output from 1 to 6 dBm, accepts multibit rates from 9.995 to 11.3 Gbits/sec, and offers the flexibility of zero or selectable chirp LiNbO3 modulators and multiple L-band tunable laser options.

A new athermal arrayed waveguide (AWG) is robust enough for outdoor fiber-optic communications installations yet precise enough to avoid unwanted increases in insertion loss or crosstalk. The athermal AWG is packaged to operate in temperatures ranging from -30° up to +70°C. The module’s design leaves the core technology of the traditional AWG-the planar lightwave circuit-intact and achieves wider temperature compensation with the packaging, instead of modifying the PLC, which would lead to higher insertion loss and higher crosstalk. The key characteristics of the athermal AWG include lower temperature dependence of the center wavelength (less than ±0.015 nm), compliance to Telcordia standards GR 1209 and 1221, and semi-flat and Gaussian spectrum shapes. The AWG is finding its way into long-haul, metro, and regional networks for multiplexing/demultiplexing or in reconfigurable optical add/drop multiplexers (ROADMs).

The G-PON integrated optical triplexer, which complies with the latest ITU-T G. 984.2 B+ requirements, is a GPON optical block intended for use in optical network terminal modules in indoor and outdoor applications. Waveguides and filters are built into silicon chips that host all electro-optical components, creating a compact device that can be mounted on a PCB. An electronic dispersion compensation chip compensates for mode-partition noise, allowing a Fabry-Perot laser to be used in the optical network unit while maintaining the 28-dB power budget and 20-km link budget. The triplexer supports a temperature range of -40° to +85°C.

A new low-loss tunable filter tunes over 120 nm from 1,510 to 1,630 nm with a full spectral sweep time of 200 msec, an autopositioning wavelength accuracy of 2 pm, polarization-dependent loss of 0.2 dB (maximum), and insertion loss of 3 dB. The 3-dB bandwidth of the filter is 0.35 nm; other bandwidths are available on request. The product is proposed in rack-mount and benchtop versions for test and measurement applications in the laboratory as well as in the field.
