Fiber optic systems are the ideal solution for transmitting large amounts of data, as they are superior to copper-based connections in some respects. These include, but are not limited to:
However, to enable data exchange between electronic systems using light pulses, these must be processed from an electrical signal and converted back after transmission. Fiber optic transceivers are used here.
A transceiver is a small optoelectronic component that is available in different sizes and performance dimensions depending on requirements. To fulfill its task - the conversion of electrical signals into light pulses - the transceiver has several components. Depending on the transmission method, the electrical signal can be encoded before being converted into an optical signal. The conversion then takes place using a light source in the transmitter, which feeds the modulated light signal into the optical fiber. Incoming light pulses are detected by the receiver component, decoded and translated into an electrical signal that the transceiver forwards to the connected board.
Basically, optical converters are divided into plug-in and on-board (also known as mid-board) versions. Plug-in transceivers offer a modular solution for optical interfaces that enable rapid adaptation to changing network requirements. They are particularly suitable for the fast connection of optical systems in easily accessible locations, as the fiber optic connection can be established using a simple plug-and-play procedure. They are preferably used in data centers, internal company networks in industry, but also used in telecommunications.
As an alternative, on-board transceivers represent a solution that enables the connection of optical and electronic systems in a smaller installation space and with less weight.
On-board transceivers enable integration in a small installation space.
Both types offer different characteristics which must be selected depending on the technical requirements of the application. Some important decision criteria for selecting the right transceiver are:
On-board transceivers are particularly suitable for use in embedded systems such as mission computing. The key factor here is the high demands placed on the assemblies. With a lower weight and a smaller form factor, the converters mounted directly on the board fit seamlessly into the systems and enable a more flexible board architecture. They support the transmission of the high data volumes that have to be processed due to a large number of subsystems and deliver reliably high signal quality even under extreme loads.
ODU offers two versions for plug-in transceivers:
Both models are based on multimode transmission with a wavelength of 850 nm and use VCSEL technology for short ranges of up to approx. 100 meters via OM4 fibers. They enable high-performance and reliable optical data transmission and are particularly suitable for applications that require high bandwidths and robust interfaces.
The combination of advanced Expanded Beam Performance technology with high-quality on-board transceivers forms the optimum transmission system for high data volumes in harsh environments. The direct connection of the optical converters to a robust interface eliminates critical weak points and ensures maximum signal quality even under the most demanding conditions.
Plug-in transceivers enable rapid adaptation to changing network environments.
