MT-V5311 Long Reach Ethernet over VDSL2 SFP Transceiver



LRE SFP MT-V5311The industry-standard SFP transceiver was defined as a hot-swappable input / output device that plugs into the fiber transceiver without having to hard-mount it on the PCB. Metanoia combines its VDSL2 chipset MT5311 with the compact SFP module in order to provide users more choices to have Ethernet connection, especially for long range extension, without needing to install a new fiber optical cable.

The LREoVD2 SFP is designed with flexible profiles settings for system integrator, or user, to select based on their different applications and environment requirements. Symmetric profile can be applied as a standard Ethernet connection while Asymmetric profile can be used for other services like Video streaming or IP surveillance services which require high traffic flow in one direction.

Furthermore, the LREoVD2 SFP supports Telco grade noise cancellation techniques like Interleaving, Forward Error Correction, high SNR margin, and retransmission that can greatly eliminate the impact of noise to ensure that service and control messages can still be securely delivered in a harsh environment. In addition, the MT-V5311 LREoVD2 SFP is an industrial grade component which ensures that it would work properly in an industrial environment.

With long reach coverage, high noise immunity, and small board size, Metanoia’s MT-V5311 LREoVD2 SFP is an ideal accessory for your enterprise and industry applications.

• Outdoor WI-FI AP Extender

As smart handheld devices become more and more popular and ubiquitous, the demand for network service with seamless mobility is also getting stronger. Therefore, Wi-Fi access service has become an important service that government, enterprises or even hotel operators must take into consideration right from the beginning. Deploying Outdoor Wi-Fi AP is a very common way for Service Providers to extend the reach of the broadband access services, which include 3G/4G LTE, in-door wireless LAN, or fixed network services such as DOCSIS, xPON and xDSL technologies.

However, the way to extend the Wi-Fi coverage at an extremely low cost still remains an elusive problem for Service Providers. Since 2-wire UTP cable used to be the most common wiring in outdoor surroundings, leveraging Metanoia LREoVD2 SFP with such existing copper cable is definitely a perfect choice to extend the Wi-Fi AP coverage up to 400 meters with symmetric 100Mbps / 100Mbps data rate. This is possible if the Wi-Fi AP includes an SFP cage.

• Mobile Backhaul Access

Using bandwidth-hungry data services such as video streaming, web conference or various types of Apps on smart handheld devices, is the most common scenario in our daily life. To catch up with the growing bandwidth demand, Wireless Service Providers have evolved from 2G/3G to LTE (4G) within few years. However, the increasing demand for bandwidth has become a burden for traditional TDM mobile backhaul network. Considering the cost and the difficulty of deployment for traditional TDM mobile backhaul network, various solutions for the last mile connection to cellular site have been proposed, including fiber, microwave and copper technologies.

Among all these solutions, although fiber technology can provide ultra-high bandwidth capacity to support the backhaul requirements of different mobile wireless networks, fixed broadband access network is definitely the most cost-efficient and the fastest to deploy, since copper pairs are commonly available on most cellular sites around the world. To meet the backhaul requirements, leveraging multi-pair bonding residential VDSL2 broadband network is a promising option for Service Providers. More importantly, it can meet the current and future bandwidth requirements for mobile backhaul without expensive wiring and complicated deployment.

With the FTTC/ FTTdp architecture, Metanoia MT-V5311 LREoVD2 SFP can be leveraged as a medium to long-term solution. In future, Service Providers can even serve those end-users with heavy bandwidth demand and video consumption by plugging optical TRx SFP to provide Gigabit data rate without having to change the CPE.

• Surveillance over IP (SoIP)

Analog CCTV (Closed-circuit Television) has been a common deployment option for industrial surveillance applications for quite some time. However, there were some disadvantages in this kind of deployment, such as the wiring limitation, transmission instability, the difficulty of real-time management, etc.

Therefore, Service Providers developed an analog surveillance system over IP networks. The main idea is to leverage a video server to collect the data from all of the analog video cameras, and use the IP network to transmit it to the control center via Ethernet cable. This approach not only enhanced the security level of data transmission but also guaranteed ease of management. As a next step, in order to improve the image quality, it becomes imperative for the Service Providers to digitize the video surveillance system. Moreover, Service Providers also need to expand their network bandwidth to transmit high quality digital video images. To address these enhancements, instead of suggesting a solution with IP cameras over 10/100 Ethernet cable, Metanoia proposes a complete solution with MT-V5311 LREoVD2 SFP. With the existing SFP cage in the managed / unmanaged switch, MT-V5311 LREoVD2 SFP can extend the Ethernet connection beyond 100m with up to hundreds of Megabits/second data rate.

• Ethernet Extender

Within the Industrial Ethernet market, the use of MSA compliant SFP interface is quite common and widely available among Ethernet switches, Ethernet Line Card Modules, media converters and other network appliances. By combining this SFP interface with Metanoia’s core VDSL2 broadband access technology, it is possible to create a perfect option for system integrators to extend the typical Ethernet coverage (100 meters) without complicated wiring and unnecessary capital expenses.

Leveraging the VDSL2 technology, Metanoia developed the Long Reach Ethernet over VDSL2 (LREoVD2) SFP transceiver, which can easily be applied in any environment with existing 2-wire cable, such as phone line, to avoid the cost of rewiring. It can dramatically extend the Ethernet service on UTP wire with distance up to 3000 meters. Furthermore, Full Duplex 100Mbps speed can be supported even up to 400 meters with standard Cat.5e 2-wire cable.
