R&M launches universal solution
offering up to 40 Gigabit
Ethernet in the LAN and data
centre
R&M is launching a universal Cat. 8.1 cabling system. It supports the fastest
data transmission local networks with structured copper cabling achieve
today: namely up to 40 Gigabit/s Ethernet. At the same time, the Cat. 8.1
cabling system is backwards-compatible as it’s based on the standard RJ45
plug-in format. This means Cat. 6A patch cords used to date can still be
deployed. Networks can still be operated with 10 Gigabit/s Ethernet which is
standard today.
Data centres and LAN operators do not need any additional adapters,
transmission cables or fibre optic interfaces if they are soon migrating to
the faster network generations 25 and 40 Gigabit/s Ethernet. After the
installation of a basic Cat. 8.1 infrastructure, faster switches and servers can
be integrated seamlessly.
The basic Cat. 8.1 infrastructure (Permanent Link) consists of two RJ45
connection modules and a shielded Cat. 8.2/8.1 S/FTP installation cable. The
system complies with both standard families: ISO/IEC 11801, Class I, and
ANSI/TIA-568.2-D.
The original intent of use for this system was in data centres, particularly
with regard to top of rack and end of row cabling. Here, Cat. 8.1 cabling is
due to transmit up to 40 Gigabit/s Ethernet (40GBase-T) in future. R&M
guarantees the performance for the 24m permanent link and the up to 30m
channel depending on the patch cords used. R&M bases its specification on
the relevant standards of ISO/IEC and TIA.
The second area of application is in buildings which require extremely fast
local data networks. Here the Cat. 8.1 system supports the new performance
level of 25 Gigabit/s Ethernet (25GBASE-T). The proposed 50m distance in
the draft technical report ISO/IEC TR11801-9909 for this bandwidth covers
roughly two-thirds of all typical link lengths in office buildings. Furthermore, the
Cat. 8.1 cabling system is suitable for four-pair Power over Ethernet (4PPoE). n
BT chooses Juniper Networks to
underpin 5G capability and move
to a cloud-driven infrastructure
Juniper Networks has been chosen by British Telecommunications (BT) to
deliver its Network Cloud infrastructure initiative. This deployment will pave
the way for BT’s Network Cloud rollout – and to also enable a more flexible,
virtualised network infrastructure that can deliver the technical requirements
of various lines of business for BT from a single platform.
BT will also use this platform to create new and exciting converged services
bringing mobile, Wi-Fi, and fixed network services together. Furthermore, with
the implementation of the Network Cloud infrastructure, BT will be able to
combine a range of currently discrete network functions and deploy them on
a cloud infrastructure that is built to a common framework and shared across
the organisation, throughout the UK and globally.
These include services across BT’s voice, mobile core and radio/access,
global services, ISP, TV and IT services, as well as a host of internal
applications, thereby cutting operational expenditure and significantly
simplifying operations throughout the organisation. n
