What are the pros and cons of using fiber optics?

Pros

• First and foremost, cable length is not an issue anymore as fiber connectivity is basically not limited in length.

• Fiber optics provide more bandwidth, as connectivity at 10 and 25 Gbps per fiber is standard today and widely used in data centers.

• Fiber optics are immune to electrical noise, which will be a significant advantage on the production floor and in some medical applications.

• Fiber optics are lighter and smaller in size than the equivalent copper cabling,

making it appropriate for applications where this characteristic is essential, like in aircrafts or vehicles.

Cons

• There is no “power over fiber”. As signals in fiber optics are transmitted using light,

there is no way to transfer power over fiber optics and devices such as cameras must be powered separately.

What are the cable options for CoaXPress-over-Fiber?

One of the most important benefits of CoaXPress-over-Fiber is the wide variety of connectivity options already available from multiple companies.

The initial connectivity options for CoaXPress-over-Fiber and the Coaxlink QSFP+ at 10 Gbps are SFP+ and QSFP+ (Quad, or four times SFP+) modules.

The advantage of using modules compared to fixed interfaces is that ports can be equipped

with any suitable type of transceiver as required by the application.

Benefits

Applications

The Coaxlink Quad CXP-12 JPEG enables the compact implementation of a multi-channel ultra-high-resolution image acquisition and recording system. The embedded pixel processing drastically reduces the CPU workload to monitor and compress image streams.

Description

• The 4-camera firmware variant of the Coaxlink Quad CXP-12 JPEG implements four independent image acquisition channels with, for each of them, a Bayer CFA decoder and a baseline JPEG encoder that can process up to 250 Megapixels/s, for a total of 1 billion color pixels per second.

• Each channel delivers two concurrent streams: a “JPEG” encoded stream for recording and a “Preview” stream for monitoring.

• The JPEG stream delivers, with a typical latency of only 20 lines, 4:2:2 full-resolution JFIF-compliant encoded images compatible with standard JPEG decoders. The JPEG encoding quality is configurable from 1 to 100.

• The Preview stream provides 8-bit Bayer full-resolution, 24-bit RGB full-resolution or 24-bit RGB low-resolution images.

Support of JFIF image format

The GenICam Browser and GenTL Viewer applications now support JFIF images.

Power over CoaXPress

What is CoaXPress-over-Fiber?

CoaXPress-over-Fiber is a light but significant extension of the existing CoaXPress specification to support transport over fiber optics.

CoaXPress (CXP) is the de-facto standard for high-bandwidth computer vision applications. CoaXPress 2.0. the latest version of the specification, specifies the CXP-12 speed, a 12.5 Gbps (Gigabit per second) link over a coaxial copper cable.

As link aggregation is common with CoaXPress, bandwidths of 5.000 MB/s (1.250 MB/s x 4) are easily achievable with four CXP-12 links. The CoaXPress specification is hosted by the JIIA (Japan Industrial Imaging Association).

CoaXPress-over-Fiber has been designed as an add-on to the CoaXPress 2.0 specification. It provides a way to run the CoaXPress protocol, as it is, unmodified, over a standard Ethernet connection, including fiber optics. As such, CoaXPressover-Fiber uses standard electronics, connectors and cables designed for Ethernet, but the protocol is CoaXPress, not Ethernet, not GigE Vision.

• One QSFP+ port compliant with 40 Gbps optical modules

• 5.000 MB/s camera bandwidth

• PCIe 3.0 (Gen 3) x8 bus: 6.700 MB/s bus bandwidth

• Feature-rich set of 20 digital I/O lines

• Extensive camera control functions
