On the other hand, similar to conventional elastic optical networks, the coarse granular routing elastic optical network also can support single or multiple modulation formats flexibly and dynamically.
With Huawei-developed core technologies, the 400G ultra high-speed solution of OSN 9800 support multiple modulation formats such as 16QAM, 8QAM, and QPSK to flexibly adapt to different bandwidth and distance requirements.
The necessity for transmission of channels with multiple modulation format (MMFs) or mixed-line rates (MLRs) may arise also as a result of different strategies of transmission network's infrastructure development performed by different ISPs [3], [4].
The Maxiva ULX UHF liquid-cooled, solid-state transmitter provides today's over-the-air multimedia broadcaster with one software defined transmitter platform capable of multiple modulation schemes.
The Maxima transmitters incorporate software-definable Harris' Apex M2X exciter technology for easy upgrade between multiple modulation schemes, as well as Harris PowerSmart technology for best-in-class power density and efficiency.
Demonstrating its commitment to provide the most comprehensive products and tools for power line communications (PLC) development, Texas Instruments Incorporated (TI) (NYSE:TXN) has announced the new PLC Development Kit (TMDSPLCKIT-V2) based on the industry's only PLC modem solution capable of supporting multiple modulation and protocol standards on a single hardware platform.
The field trial, conducted over live fiber links in a 610km span of a leading European service provider's fiber optic network, showcased transmission of multiple single-lambda 200G channels (30x200G) over the full distance of 610km using multiple modulation schemes (QPSK, 8QAM, and 16QAM), with successful demonstration of bandwidth variable transponder capabilities and excellent margin performance.
These new additions to the VISLINK Wireless Camera Suite provide multiple modulation schemes to maximize video quality and minimize drop-outs.
These transmitters incorporate software-definable Harris Apex M2X exciter technology for easy upgrade between multiple modulation schemes, as well as Harris PowerSmart technology for best-in-class power density and efficiency.
The SRU2 features multiple modulation schemes from quadrature phase shift keying (QPSK) to 4096 quadrature amplitude modulation (QAM), and its maximum RF bandwidth for one single channel can support up to 112MHz.
Huawei's DOCSIS 3.1-based distributed CCAP solution employs Orthogonal Frequency Division Multiple Access (OFDMA) in the upstream to support simultaneous access of multiple users over a single coaxial cable, and broadcasts data to downstream users divided into different groups using the multiple modulation profile (MMP) technology, drastically enhancing the spectrum efficiency.
With so many different types of fax machines and proprietary methods for exchange, more law enforcement professionals are purchasing software that can handle multiple modulations as well as standard and vendor specific protocols.
