X-ray measurement zooms in on defects
Data-Pixel, a specialist manufacturer of metrology equipment for the fibre-optics industry, is adding X-ray measurement services to its portfolio. The company claims that X-ray imaging techniques like real-time digital radioscopy or 3D computer tomography are among the most accurate forms of non-destructive testing available on the market today. They can be used to detect material defects such as porosity, fissures and bubbles for quality-control purposes in a wide range of components applications, including optical connectors and microelectronics. The sample X-ray analysis services will be offered through Data-Pixel's subsidiary, RX-Solutions, which also sells custom-made X-ray imaging equipment for production line or laboratory use.

Compact gain block targets 40G designs
Bookham of the US is launching an ultra-compact small form factor amplifier gain block that is 72% smaller by volume than an MSA-standard amplifier gain block. The MiNiBlock μ7040 is primarily targeted at 40 Gbit/s transport systems in which low-noise optical amplification is required for each channel before the 40 Gbit/s receiver, and space is at a premium. Measuring just 70 x 40 x 7.5 mm, the ultra-compact amplifier can also support designers looking to integrate optical amplifiers into the standard transponder footprint.
The MiNiBlock μ7040 offers output power of up to 15 dBm and produces only 1.2 W of heat. The product is enabled by the industry-leading Bookham MiniDIL uncooled 980 nm pump module.

WSS is optimized for two-degree ROADMs
Xtellus, US, says that its new wavelength-selective switch (WSS) is optimized for two-degree reconfigurable optical add–:drop multiplexer (ROADM) nodes. The 2x1 EdgeWSS accepts DWDM traffic from an input port and add port, and selects which wavelengths to route to a common output port, while balancing the power on those wavelengths. The device can also be operated in reverse, with a single input distributing wavelengths to two outputs.
The 2x1 EdgeWSS supports both 50 and 100 GHz channel spacings and offers high optical performance, which is characterized by wide, flat-top passbands, low insertion loss and polarization-dependent loss, low dispersion and high extinction. The liquid-crystal-based 2x1 EdgeWSS is dark at power off, eliminating the need for an external shutter. Optimized for metro optical networking equipment, it is packaged in a compact module that will fit into a single line-card slot.

GPON transceiver aims for European markets
Fujikura Europe is launching its first pluggable Gigabit Passive Optical Network (GPON) transceiver aimed at fibre-to-the-home (FTTH) network system vendors in the dynamic European market. "At Fujikura we have an established offering for EPON [Ethernet PON] – built on our extensive experience in the Japanese market – but feel that we can capture the market for GPON transceivers with this product launch," commented Fujikura Europe's Simon Richardson.
Boasting true GPON G.984.2 performance, the SFP (small form factor pluggable) format helps carriers to reduce expenditure through decreased "down time" and improved inventory management. The pluggable format also enables operators to scale their deployments as demand increases, adding further GPON lines to meet requirements.

Narrow linewidth suits coherent transmission
Eblana Photonics, Ireland, has started commercial shipments of its EP1550-NLW-B Narrow Linewidth semiconductor laser product series, which has guaranteed emission linewidths of 400 kHz and below. "A key impact of our technology on the product's performance is that the laser emits in an ultra-narrow line even at low emitted powers, unlike DFB lasers that have to be driven at extreme operating points to achieve even MHz linewidths," said James O'Gorman, Eblana's founder.
Eblana's lasers are being used in high-bandwidth coherent communications applications where, for example, high spectral efficiency, phase-encoded signals are used to overcome transmission bottlenecks. The product is supplied in an industry-standard hermetically sealed 14-pin butterfly, integrated with optical isolator, thermo-electric cooler, thermistor and power-monitor photodiode, and each device is shipped with the individual test data of the measured linewidth.

Locking device makes reliable connections
Connector specialist Harting of Germany says its new range of products for telecoms outdoor solutions combines the advantages of the reliable Harting PushPull locking system with innovative inserts for fibre optics based on standard LC fibre-optic connectors. These robust Harting interfaces offer protection from vibration, water and dust with degree of protection IP 67/65 as standard. Power solutions and data connectors for the IP 20 environment complete the range.
Harting says that the product range is ideal for applications such as FTTA (fibre-to-the-antenna), FTTH (fibre-to-the-home) or WiMAX, where reliable outdoor connectivity is needed.

Wall-mounted cabinet is lightest in the range
TeraOptic of France will display the new Jeddah wall cabinet, which allows the management of 144 splices and 96 connections of all types in a keylock-secured compartment. Weighing just 10 kg (excluding the protective module), the vendor claims that the Jeddah is the lightest cabinet in its range and is easy to manipulate and fix. There are four cable entry points on each of its lower and upper faces, which are secured by waterproof systems such as cable glands. The splicing tray is mounted on a movable plate that pivots to allow access to the internal volume of the cabinet, making it possible to carry out splicing operations easily.
