OMC’s bespoke fibre optics for IIoT
Optoelectronics design and manufacturer OMC, now offers a bespoke fibre optic datalink design & manufacturing service for Industrial IoT (IIoT) applications that require secure information transmission in environments that suffer from electrical interference or contain combustible dust which can cause explosions. The company says that industrial fibre optic data communications links use LED sources, solid-state receivers and glass or plastic fibre to transmit data safely and reliably in industrial systems. The fibre SMA connector remains widely used in the industrial sector due to its excellent track record and ‘fit and forget’ nature. Polymer (plastic) fibre is often preferred for short transmission lengths due to its inherent
Moreover, OMC’s proprietary ACA™ (Active Component Alignment) technology ensures that its fibre optic datalinks perform reliably, with 100% link consistency. During the datalink manufacturing process, each transmitter and receiver device is powered up, before the launch power or receiver sensitivity is measured, aligned and secured in place, with the device characteristics recorded and assured to be within the requisite performance envelope for the specific application. This enables much tighter performance tolerances to be achieved, leading to greatly enhanced long-term reliability – and in particularly demanding applications, this can be combined with OMC’s proprietary KSMA™ connector, with identifiable channel numbering, to ensure that the entire link performance measured during manufacture is, by design, repeated in the field.
robustness and low cost. OMC produces its own transmitter/ receiver (Tx/Rx) components, as well as both polymer and glass fibre optic assemblies. Therefore,
the company can design and deliver fully characterised fibre optic datalinks that meet the specific requirements of a wide range of applications.
Coherent’s uncooled micro-pump laser
Coherent Corp. has unveiled an uncooled dual-chip 980 nm micro- pump laser delivering a 2×400 mW output. The new laser is delivered in a compact 3-pin module, for next-generation coherent transceivers in data centre interconnects and in compact single- channel and bidirectional amplifiers for metro and long-haul networks. Next-generation coherent transmission applications continue to demand amplifiers that can operate efficiently in space- and power-constrained environments and in a wider operating temperature range outside the central office. Single-mode uncooled dual- chip micro-pump lasers from Coherent offers a 2×400 mW with power consumption of less than 2 W in environments where temperatures can range from -20 to 85 degrees
Celsius. Equipped with an internal fibre grating for wavelength stabilisation combined with a reduced- clad, bend-insensitive 80 μm single-mode fibre, the pump device can support a 5 mm bending radius, complementing the ultra- compact 10 mm x 4.4 mm footprint of the device. Device samples are available now. Qualification and volume production of the new uncooled dual-chip micro-pump laser is on track for Q1 CY2025. The company says uncooled modules help address the growing need for energy- efficient communications networks at a lower cost of ownership by reducing overall power consumption and eliminating much of the thermal and power management systems associated with cooled lasers.
