Optical fibres - Part 1-41: Measurement methods and test procedures - Bandwidth
Käsitlusala:
IEC 60793-1-41:2024 describes three methods for determining and measuring the modal bandwidth of multimode optical fibres (see IEC 60793-2-10, IEC 60793-2-30, and the IEC 60793‑2‑40 series). The baseband frequency response is directly measured in the frequency domain by determining the fibre response to a sinusoidaly modulated light source. The baseband response can also be measured by observing the broadening of a narrow pulse of light. The calculated response is determined using differential mode delay (DMD) data. The three methods are:
Method A – Time domain (pulse distortion) measurement
Method B – Frequency-domain measurement
Method C – Overfilled launch modal bandwidth calculated from differential mode delay (OMBc)
Method A and method B can be performed using one of two launches: an overfilled launch (OFL) condition or a restricted mode launch (RML) condition. Method C is only defined for A1-OM3 to A1-OM5 multimode fibres and uses a weighted summation of DMD launch responses with the weights corresponding to an overfilled launch condition. The relevant test method and launch condition is chosen according to the type of fibre.
NOTE 1 These test methods are commonly used in production and research facilities and are not easily accomplished in the field.
NOTE 2 OFL has been used for the modal bandwidth value for LED-based applications for many years. However, no single launch condition is representative of the laser (e.g. VCSEL) sources that are used for gigabit and higher rate transmission. This fact drove the development of IEC 60793-1-49 for determining the effective modal bandwidth of laser optimized 50 µm fibres. See IEC 60793-2-10 and IEC 61280-4-1 for more information.

Fibre optic interconnecting devices and passive components - Study of an SC connector adaptor with safety lock mechanism
Käsitlusala:
IEC TR 63323:2024 deals with a new proposal for an SC adaptor connector which includes a flexible retaining element on its top surface, compared to the SC standard adaptor.
With this solution, when the SC plug connector is in place, any accidental disconnection is difficult, as it employs an external tool or a particular unlocking manoeuvre.
This new adaptor is intended primarily for the home network customer optical fibre termination, but it can be used in every situation where safety issues are important (e.g. main distribution frames in central offices, cross-connect cabinets, street cabinets, termination boxes).
It consists of a push-latch-pull mating sequence connection with the assistance of a suitable tool.
This solution assures compatibility with the existing SC interface standard according to IEC 61754-4.

Cyber Security for Consumer Internet of Things: Baseline Requirements
Käsitlusala:
The present document specifies high-level security and data protection provisions for consumer IoT devices that are connected to network infrastructure (such as the Internet or home network) and their interactions with associated services. A non-exhaustive list of examples of consumer IoT devices includes:
• connected children's toys and baby monitors;
• connected smoke detectors, door locks and window sensors;
• IoT gateways, base stations and hubs to which multiple devices connect;
• smart cameras, smart speakers and smart TVs together with their remote controls;
• wearable health trackers;
• connected home automation and alarm systems, especially their gateways and hubs;
• connected appliances, such as washing machines and fridges; and
• smart home assistants.
Moreover, the present document addresses security considerations specific to constraints in device resources.
EXAMPLE: Typical device resources that might constrain the security capabilities are energy supply, communication bandwidth, processing power or (non-)volatile memory capacity.
The present document provides basic guidance through examples and explanatory text for organizations involved in the development and manufacturing of consumer IoT on how to implement those provisions. Table B.1 provides a schema for the reader to give information about the implementation of the provisions.
Devices that are not consumer IoT devices, for example those that are primarily intended to be used in manufacturing, ealthcare or other industrial applications, are not in scope of the present document.
The present document has been developed primarily to help protect consumers, however, other users of consumer IoT equally benefit from the implementation of the provisions set out here.
Annex A (informative) of the present document has been included to provide context to clauses 4, 5 and 6 (normative). Annex A contains examples of device and reference architectures and an example model of device states including data storage for each state.
