MTP connector kit
Using the new MTP (MPO-style) connector, compatible with round, stranded cable, has benefits compared to rectangular ribbon cable terminations without sacrificing high density, such as eliminating preferential bends, better aramid yarn distribution during assembly, easier routing during long cable length installation, and generally lower cable cost. The connector design has been fully qualified for multimode and singlemode applications according to standard industry requirements.

Tera Flow bend-insensitive assemblies are less susceptible to bend-induced losses in the C-band (1,530 to 1,565 nm) and L-band (1,565 to 1,625 nm). They will operate with a bend radius as small as 0.6 inches (15 mm); for comparison, the minimum bend radius of standard SMF-28e is 1.2 inches (32 mm). Available jacket sizes are 900 µm, 2 mm, and 2.9 mm, with simplex and duplex configurations.

The MSA-compliant S3600 integrable tunable laser assembly (ITLA) comes in a compact, standardized form factor designed for incorporation into a 300-pin transponder or DWDM line card. The S3600 includes additional features such as SBS suppression dither, TxTrace, off-grid tuning, and “in-operation” adjustable transmit output power. Fault detection and intervention are provided along with wavelength, temperature, bias, and power monitors and alarms.
A 3.2-Gbit/sec CML limiting post-amplifier, the SY88343DL is designed for use in fiber-optic receivers. The IC features high-gain TTL loss-of-signal detection for applications such as passive optical networks; Gigabit Ethernet; 1X and 2X Fibre Channel; SONET/SDH OC-3/12/24/48, STM-1/4/8/16; and high-gain line drivers and line receivers. The chip connects to a typical transimpedance amplifier (TIA), which outputs a linear signal output that can contain significant noise and may vary in amplitude. The SY88343DL is able to quantize these signals and output CML-level waveforms to ensure low noise levels.
A new generation of electro-optic (EO) modulators uses EO polymers as active rectangular waveguides, replacing single-crystal LiNbO3. Optical fibers in the modulator are modified by replacing a small area of passive cladding with an active multilayer structure. The cladding includes a thin layer of an EO material sensitive to electromagnetic fields. In the presence of an external electromagnetic field, the optical properties will change as well as the transmission characteristics of an optical signal propagating within the fiber core. The technology is highly efficient and provides low signal-to-noise ratio. The modulators can also be used as high-speed switches with a high-speed electric signal applied to the active cladding material in the modified section of the optical fiber.

Fiber distribution hub
The ORBITAL 576 fiber distribution hub (FDH) is a new addition to the Access ADVANTAGE System. The FDH can be installed using quick-to-provision modular splitters and factory-installed connectorized cables, and is easily scalable to higher-bandwidth architectures. Designed to serve up to 576 homes, the FDH features proprietary MPO optical splitter modules, low-loss PLC splitters, and high-performance LC and MPO connectors. All subscriber fibers are routed from the splitter modules to a central hub, then to subscriber ports arranged in a circular array surrounding the hub.
Several levels of fiber-optic cleaning kits are available, ranging from the economy level for occasional connector cleaning and maintenance, to a complete kit for frequent cleaning of multiple connector and/or fiber types. The economy kit includes Hydrosorb wipes and solvent in a durable carrying case. The complete kit allows for multiple cleaning methods for any connector type, and includes Cletop type A and B cleaning cassettes, replacement tape, solvent, 1.25- and 2-mm swabs, Kim wipes, and Hydrosorb wipes in a carrying case.
The OptiSplice Ribbon Splicer is a handheld 1-to-12-fiber fusion splicer designed specifically for next-generation FTTX applications. The splicer provides improved speed and performance when compared to previous generation multifiber splices, all in a handheld package. The OptiSplice One Fusion Splicer is the next-generation single-fiber splicer, featuring an intuitive user interface, dual cameras, tool-free maintenance, an ultrafast heat-shrink oven, and high-capacity Li-Ion battery in a reduced size. Both units are available with modular accessories for use in FTTX applications including aerial, ground-level, and at the home.

Carrier Ethernet validation on test platform
The N2X test platform now incorporates Net-O2’s ATTEST Layer 2 conformance test technology, which combines ATTEST protocol test cases with the N2X conformance test manager. The Layer 2 conformance test suites offer a validation tool comprising more than 450 individual test cases, which saves time on script development. The test suites include the N5712A Spanning Tree, N5713A Rapid Spanning Tree, N5714A Multiple Spanning Tree, and N5715A Link Aggregation Control Protocols.
New test modules and software are available on the OptiFiber Certifying OTDR. Users can now test longer fiber links in campus networks, as well as very short patch cords in data centers. The OTDR’s extended-range singlemode module offers a 60-km range, shorter dead zones, and increased dynamic range to support premises, campus, and metro fiber-optic network testing. The modules’ improved end-cap design features removable, easy-to-clean OTDR ports and interchangeable power meter ports. A visual fault locator is also included for fast visual identification of fiber breaks or tight bends.
The multifunction optical test platform (MOTP) allows users to quickly and easily implement custom test setup for manufacturing, prototype, lab, and R&D optical tests. In addition to its internal built-in functions to control the tunable laser source (or an ASE source), VOA, polarization controller, and power monitor functions, add-on options such as VOA, polarization-control, optical switch, power measurement, wavelength monitor, or other user-defined modules can be installed. The tester has a wavelength range of 1,530 to ~1,570 nm, wavelength resolution of 50 nm, and dynamic range of 60 dB.
NIC platform instruments can now be equipped with ODU-1 to ODU-2 multiplexing capability. The new test option enables NIC products to multiplex/demultiplex four ODU-1 signals within ODU-2 on an Optical Channel Transport Unit (OTU)-2 interface. The systems confirm proper operation of network equipment during R&D, field implementation, and ongoing maintenance. The multiplexing test option is available on the NextGen Multi-Rate (NGMR) module, which supports 10GbE LAN, 10GbE WAN, and 10G FEC, in addition to SONET/SDH from 51 Mbits/sec to 10 Gbits/sec, and the OTN rates of OTU-1 (2.66 Gbits/sec) and OTU-2 (10.7 Gbits/sec). The NGMR module is available on all NIC products to enable single-module telecom and datacom testing.
