PoE Powered Office Automation

PoE Powered Office Automation

The concept of modernized enterprise office is heavily leveraged high speed network environment more and more. It becomes the challenge of the IT department of enterprise for the office layout. It’s not only for artistic and orderly purpose but also the centralized management and IP based structured cabling to be considered. There are more factors to be concerned for the office layout such as security, mobility, simplified asset management and energy saving. In some large building, the traditionally UTP cooper cabling have been not able to fulfill the requirements for the IT administrators to well organize the overall office layout.

Distance Extension of Fiber Network

There is often the challenge when deploys the network no matter what either telecom operator or enterprise. How is the network able to extend the distance as expected? Or is it possible to convert the dual fiber and single fiber with the existed cable laid and equipment with the minimum efforts?

Integrated Copper and Fiber Connection for Campus Network

In this application example, CTC Union ‘s FE and GbE media converters are deployed in a star topology network with Multiple fiber links distributed from a central location. CTC Union’s Ethernet media converters provide copper-to-fiber conversion for data rates of 10 Mbps up to 1000Mbps.

Business Connection Service

The network interface device (NID) is a kind of equipment which works as the concept of Ethernet service demarcation defined by MEF (Metro Ethernet Forum). The carrier operators or service providers can deploy NID to enterprise subscribers then provide the point-to-point E-Line or multipoint-to-multipoint E-LAN service which is logically Ethernet virtual connection to replace the legacy TDM based lease line service.

IP Backbone Transportation for Broadband Access Network

In this application example, the PON technology remains one of the most popular deployment scenarios for FTTX in the world today. To meet network and subscriber management requirements, the OLT equipment at the central site will always require communication with subscriber management equipment such as DHCP server, provisioning server or NMS based over IP. Connecting the OLT equipment to the Ethernet demarcation device simplifies the deployment to transport the traffic over the Metro Ethernet network.

CPRI and OBSAI over CWDM Fronthaul to Cell Towers

This application illustrates how to transport four Common Public Radio Interface (CPRI) channels over one fiber fronthaul link using Coarse Wavelength Division Multiplexing (CWDM). The CTC Union FRM220 CWDM MUX/DEMUX, OADM and 3R Transponder enable CWDM connectivity in a C-RAN (Cloud-Radio Access Network) over a fronthaul fiber link between Base Band Units (BBU) and Remote Radio Heads (RRH) located at two different cell towers.

Mobile Fronthaul and Backhaul Solution

This application will illustrate how to transport Common Public Radio Interface (CPRI) or Open Base Station Architecture Initiative (OBSAI) channels over one fiber fronthaul link using Coarse Wavelength Multiplexing (CWDM) then integrating into IP Ethernet based carrier network as mobile backhaul transportation solution for mobile operator. The CTC Union FRM220 CWDM MUX/DEMUX, OADM and 3R Transponder enable CWDM connectivity in a C-RAN (Cloud-Radio Access Network) over a fronthaul fiber link between Base Band Units (BBU) and Remote Radio Heads (RRH) located at two different cell towers.

Wireless Access & Data Offloading

With the Smartphone and tablet as the popular device of everyone to access the internet information such as streaming video & audio, community APP…etc on the go, the bandwidth of wireless access is demanding by each mobile subscriber. Even most of mobile network operators had expedited to migrate their network from 3G/3.5G to 4G LTE, the WiFi hotspot is still the most cost effective solution to make the mobile operators keep the service quality for subscriber’s loyalty in many congested 3G/3.5G or even 4G cellular network regions such as shopping mall, stadium, restaurant, crowded downtown area, airport and so on.
