Singapore (April 1, 2013) -FCI is a leading manufacturer of high-speed I / O optical fiber and copper cable interconnect systems. It has developed a 12-channel on-board optical module (OBT) capable of transmitting 25Gb / s per channel signal of. A single optical module device has 12 transmission channels and 12 receiving channels. The design is to minimize the space required on the PCB substrate surface, while taking into account the convenience of application and disassembly or maintenance.
Minimize signal loss, and connect the input and output on-board optical modules through a high-density front panel fiber optic cable system. The system is equipped with small-size fiber optic adapters and multi-fiber cable assemblies that can provide a port-to-port density of 12.5 mm and 12–48 fibers per port.
The on-board optical module device adopts a new pluggable optical interface and lens-based coupling elements, which can be easily mated and removed. The onboard fiber optic transceiver is connected to the PCB through a pluggable optical interface, and enables quick and easy assembly and disassembly when needed.
"The design of FCI's new onboard transceivers addresses the development trends of some emerging industries and the needs of hardware designers," said Sven Otte, Engineering Manager / Supervisor of FCI Optical Products. "These trends and needs, such as minimizing the PCB footprint Occupying space, eliminating high-speed signals on the backplane to minimize signal loss, 25Gb / s + transmission capacity per channel, and convenient application, use, and replacement are all addressed in our OBT package. "
Although OFC / NFOEC's on-board optical module demonstration will illustrate 12-channel capabilities, OBT can also be configured for lower bandwidth, for example, 4-channel operation with 25Gb / s transmission capability per channel may be the preferred configuration. According to customer needs and requirements, other custom configurations can be made.

The fixed and rotor iron cores of large motors are divided into many overlapping segments. The punch plate of spot welded ventilation channel steel is placed between the iron core segments, namely, the ventilation groove plate, so as to form the radial air duct of fixed and rotor iron cores, which is used for heat dissipation and ventilation cooling of iron cores. The manufacturing quality of the ventilation groove plate must meet the strength requirements to ensure that no collapse or collapse occurs after loading. At the same time, the spot welding position of the ventilation channel steel on the punching plate should be accurate. After each section of iron core is pressed, the axial position of the ventilation channel steel should be in a straight line to ensure that the radial air duct does not distort and the axial straight line transmission of the pressing force of the iron core.
With the development of motor manufacturing technology and upgrading of manufacturing equipment, the manufacturing technology level of ventilation groove plate has been greatly improved. Currently supported processes are resistance welding and laser welding. Resistance welding is to place the welding parts between two electrodes, connect the current and apply a certain pressure, use the resistance heat generated when the current flows through the workpiece contact surface for heating, forming the local melting state of the welding parts. Laser welding is a kind of laser beam with high monochrome, strong aroma and high brightness by using the principle of excited atomic radiation. The laser beam, which is composed of coherent monochromatic photon stream with high energy density produced by laser, is used as energy source to bombard metal or non-metal, generate heat and melt it to achieve the purpose of welding.
According to the different requirements of the structure design and the characteristics of the respective spot welding process and the actual production needs, the motor manufacturers can
According to their own design capacity, equipment situation, production cycle, choose suitable for their own ventilation groove plate spot welding process, to ensure the manufacturing quality of ventilation groove plate.
