For metro edge, storage, and access networks, including CWDM, Gigabit Ethernet, and PON systems, the P1X series LX4 5-, 8-, and 9-channel mux/demuxes are based on the precision arrayed and combined solutions (PACS) architecture. The 5- and 9-channel devices address the need for 4+1 and 8+1 configurations in applications requiring an “express” channel. All versions utilize the standard ITU CWDM wavelengths. The use of a micro lens array and thin-film filters very precisely mounted in a glass block assembly, working in conjunction with an integral mirror, ensures low insertion loss, good channel uniformity, and respectable crosstalk performance. The devices contain just seven parts, resulting in an ultra-compact form factor of 14.5×7.2×4.7 mm.
For use in the 1310-nm window and 1550-nm wavelength region, the OH-LiteT low-loss singlemode fiber has low water peak, low chromatic dispersion, and minimal PMD. It complies with ITU G.652.C/D and IEC 60793-2-50. For LANs (including backbone, riser, and horizontal) with video, data, and/or voice services using LED, VCSEL and Fabry-Perot lasers sources at 850 or 1300 nm, the Giga-LiteT high-performance multimode fiber is designed for laser-based Gigabit Ethernet (IEEE 802.3) applications and fully compatible with legacy systems. The 50/125- and 62.5/125-µm variants offer high overfill bandwidth, exceeding the requirements for slower legacy protocols like Ethernet, FDDI, Fast Ethernet, ATM, and Fibre Channel. SuperLANT cables, available in Category 5e and 6 variants, are suitable for transmission of high-speed data, digital and analog voice, and video signals on LANs. They support GbE standards and are compatible with all common systems according to EN 50173, ISO/IEC 11801, and TIA/EIA 568-B.

The BendBright singlemode fiber combines low-bend sensitivity with full-spectrum performance, providing enhanced bend performance across the entire 1310-1625-nm spectrum. ITU-T G.652.D-compliant and fully compatible with other conventional singlemode and full-spectrum fibers, it supports bends and loops half the diameter required at traditional wavelengths, with bend diameters down to 15 mm, allowing the use of more compact splice trays, pedestals, and access terminals.

The compact rugged 2178-XSB fiber-optic splice closure can withstand the most severe OSP conditions of moisture, vibration, and extreme temperatures in long-haul, metro, local access (DSL, HFC, mobile wireless backhaul), and FTTP feeder and distribution networks. The closure is easily re-enterable to allow access to splices and the addition of drops or small-diameter cables. Specifically designed only for butt-splicing applications, the closure has three cable entry ports: two 1-inch ports and a 1.4-inch port. The multiport grommets, which accommodate flat, round, and various diameters of cable, provide for simple, flexible, and futureproof drop or small-diameter branch cable additions. The closure’s maximum single fusion and mass fusion splice capacity is 48 fusion and 144 ribbon fibers.
The OptiSheathPremier FlexNAP terminal distribution system consists of an optical cable pre-installed with network access points (NAPs) (terminals) at customer-specified locations and a tethered, environmentally hardened MT connector. That allows the system’s cables to pass homes without the need for terminal placement or fusion splicing prior to service being offered or subscribed. Once measurements for terminal locations are obtained, the system is manufactured and tested. The entire system is then packaged and shipped to the customer for immediate deployment. Once service is offered or required, an OptiSheath terminal, equipped with an environmentally hardened MT plug, is plugged in and the subscriber is ready to be connected. FTTX network installations are completed faster and more easily and efficiently so more highly skilled workers can be assigned to other areas of the network.

With a forgiving 1:1 mix ratio by weight or volume, the EP37-3FLF two-component optically clear epoxy system bonds well to a wide variety of substrates, including metals, glass, ceramics, rubber, and many plastics, cures at room temperatures, and resists impact, shock, and severe thermal cycling. The adhesive/sealant also can be used as a potting and encapsulation compound. Its low exotherm makes it a suitable material for large castings, and it possesses superior electrical insulation properties and an exceptionally long working life. The epoxy’s service operating-temperature range is -80° to +250°F, volume resistivity is 1×1014 ohm-cm at 75°F, Shore D hardness is 30, and tensile strength is 4,000 psi at 75°F. Peak exotherm for 200-gm mass is 40°C. The epoxy comes in pint, quart, gallon, and 5-gal kits; syringe applicators are also available. It can be stored at room temperature and has a shelf life of one year.

The GPON ONU/ONT triplexer reference design meets demanding specifications for analog video-receiver performance, including 50-870-MHz bandwidth, 48-dB CNR or better, wide dynamic range of -6 to +2 dBm, and 16-dBmV/channel RF output. The digital-transmitter section supports rates of 155 and 622 Mbits/sec and 1.24 and 2.48 Gbits/sec with output power capability from -4 to +4 dBm. The digital-receiver designs support downstream rates of 2.48 Gbits/sec, 1.24 Gbits/sec, and 622 Mbits/sec with -25, -29, and -32-dBm sensitivity, respectively. The triplexer reference design uses off-the-shelf variable-rate ICs suitable for standard BPON (622 Mbits/sec downstream/155 Mbits/sec upstream), GEPON (1.24 Gbits/sec upstream/downstream), and GPON applications (up to 2.5 Gbits/sec downstream/upstream). Discrete reference design support for optical block customers includes schematic and Gerber files, detailed BoM, sample boards with complete test data sheets, and manufacturing application support for two methods of PCB attach of optical blocks to PCB.
