For example, the ESA advocates a derivative standard called
The IEEE 1355 and

and IEEE 1355 DS-DE allows for a wider set of speeds for data transmission, and some new features for automatic failover. The fail-over features let data find alternate routes, so a spacecraft can have multiple data buses, and be made fault-tolerant.
also allows the propagation of time interrupts over
links, eliminating the need for separate time discretes.
SpaceWire's modulation and data formats generally follow the data strobe encoding - differential ended signaling (DS-DE) part of the IEEE Std 1355-1995.
utilizes asynchronous communication and allows speeds between 2 Mbit/s and 400 Mbit/s. DS-DE is well-favored because it describes modulation, bit formats, routing, flow control and error detection in hardware, with little need for software.
also has very low error rates, deterministic system behavior, and relatively simple digital electronics.
replaced old PECL differential drivers in the physical layer of IEEE 1355 DS-DE by low-voltage differential signaling (LVDS).
also proposes the use of space-qualified 9-pin connectors.

supports highly fault-tolerant networks and systems, which is one reason for its popularity.
Many high-performance interconnects including Myrinet, Quadrics, IEEE 1355, and
support source routing.
The RAD5500 platform supports VPX high speed connectors, DDR2/DDR3 memory, serialize/deserialize (SerDes), and

IEEE 1355 and
are a family of simplified physical-layer standards very similar in function at the hardware level to MPLS.
As of 2014, there are three different models of the NEXTAR standardized platform. All feature a common core of features like using the
communications protocol, the SpaceCube2 on-board computer and autonomous control functions. The different models are:
is a spacecraft communication network based in part on the IEEE 1355 standard of communications. It is coordinated by the European Space Agency (ESA) in collaboration with international space agencies including NASA, JAXA and RKA.

. It is sometimes used for digital data connections between scientific instruments, controllers and recording systems. IEEE 1355 is used in scientific instrumentation because it is easy to program and it manages most events by itself without complex real-time software.
Data from the image sensors (Focal Plane Arrays) is collected by the Focal Plane Electronics and sent to the ISIM computer. The data between the FPE and the ISIM computer is transferred by
connection. There are also Instrument Control Electronics (ICE). The Focal Plane Arrays contain 40 million pixels.
In the mid-1970s he formed a new company, Microcomputer Analysis Ltd, which offered consultancy on microprocessors to the semiconductor industry. This brought him into contact with two eminent American semiconductor specialists, Richard Petritz and Paul Schroeder, and in 1978 the triumvirate founded Inmos International PLC, which produced the innovative transputer, and led to the development of
is very similar to DS-DE-02, except it uses a microminiature 9-pin "D" connector (lower-weight), and low voltage differential signaling. It also defines some higher-level standard message formats, routing methods, and connector and wire materials that work reliably in vacuum and severe vibration.
The infrared detectors for the NIRCam, NIRSpec, FGS, and NIRISS modules are being provided by Teledyne Imaging Sensors (formerly Rockwell Scientific Company). The James Webb Space Telescope (JWST) Integrated Science Instrument Module (ISIM) and Command and Data Handling (ICDH) engineering team uses
to send data between the science instruments and the data-handling equipment.
