Synchronisation is one of the most critical functions of a communication system; however, in the context of 5G, especially for Time Division Duplex (TDD) where both uplink and downlink transmission is on the same frequency, the possibility of interference is much more significant. As a result, we see more stringent requirements for timing and synchronisation for both TDD LTE and 5G-NR. In this paper we will discuss the relationship of TDD, timing and synchronisation, and frame synchronisation especially for 5G TDD deployments.

Passive intermodulation (PIM) has been one of the most common and recurrent problems in cellular networks, particularly in mobile services with a frequency division duplex (FDD) communication mode where PIM signals interfere with mobile transmissions (uplink).

Breakthrough technologies that are integral to 5G, such as Massive MIMO, network slicing, beamforming and network function virtualization (NFV) necessitate phased approaches to 5G deployment, as well as significant investment, with telecom companies expected to spend upwards of $300 billion on 5G network deployment over the next decade. This monumental task lends itself to a wide variety of strategies and options, each with inherent benefits and drawbacks. 

FiberComplete™ is the industry’s first all-in-one solution that tests bidirectional insertion loss (IL), optical return loss (ORL), and OTDR with automatic, one-button ease. Double your test efficiency and certification-reporting speed with FiberComplete. Remove the guesswork, automate processes, and streamline workflow with FiberComplete, and make even novice technicians experts.

Empower network engineers to more simply investigate problems and resolve them more swiftly to everyone’s satisfaction. Whether your ‘end user’ is a person or an application, when they experience issues it often results in network engineers having to piece together information from a variety of sources and metrics to try and work out what exactly the user experienced and who the owner of their problem really is. It feels like nine times out of ten it’s the network that unfairly gets the blame!

Not all switches are created equal... So what makes the difference? The real difference between all switch manufacturers is the ASIC (switch silicon). Most manufacturers rely on merchant silicon from companies such as a Broadcom*. This is where we think Mellanox Spectrum is different; Mellanox offers a game-changing ASIC that can transform your network and supercharge your data centre.

Plus tunable DWDM wavelengths giving you up to 88 200G channels. Combine multiple different client side data rates. Why settle for 100G when you can have 200G for no additional cost? Pluggable 100G/200G multiprotocol, multirate, multireach muxponder with twenty multiprotocol SFP+ client ports. Multiple configuration options (20 x 10G; 2 x 40G + 12 x 10G; 4 x 40G + 4 x 10G). Single integrated coherent FlexRate 100G/200G line port with DynaFEC and SD FEC.

Find out how quick and easy it is to use Alien Wavelengths on top of your DWDM network to increase your bandwidth. An “alien” wavelength is any wavelength that originates on networking equipment that is not the same as the equipment used in the optical line system. It can be from a different type of equipment such as a router with colored optics connected to an optical line system even if they are both from the same vendor.
