This application is a non-provisional of, claims the benefit and priority of, Taiwan(R.O.C) provisional Application No. 110104861, filed Feb. 9, 2021, which is incorporated herein by reference in its entirety.
Example embodiments relate generally to the field of data communications and, more particularly, to a multi-system optical communication switching module and the method thereof.
Driven by the ever-growing computing demands of cloud users, generation of massive amounts of data by edge computing devices such as Al-enabled IoT devices, and roll-out of 5G networks, the architectures of hyperscale, colocation and on-premise data centers have been forced to rapidly evolve. Also, new data centers closer to end-users or devices are being built as the demand for services that rely on edge data centers increase.
For data centers, whether it is new builds or network upgrades, proper cabling infrastructure is required for successful application delivery within the data centers. The cabling infrastructure must be reliable, easy to install, modular and flexible, to accommodate changes, and scalable to support data center growth. In general, the cabling infrastructure connects the end and intermediate points of traffic patterns within the data centers to and from routers, interconnection switches, access switches, servers, SAN switches and storage. Of the types of cabling employed in data centers, coaxial cables continue to play an important role in different parts of the network infrastructure, such as short reach connections at the server, switch and top or rack layers.
Generally, Fiber To The x (FTTx) is a collective term used to describe network architecture. The “x” representing the fiber termination point. That is, the FTTx technology enables a terminal point to directly connect to the data center. The FTTx technology includes optical fiber deployments such as Fiber To The Curb (FTTC), Fiber To The Building (FTTB) and Fiber To The Home (FTTH). Generally, there are mainly two types of optical communication systems. The two systems are called Active Optical Networks (AON) and the Passive Optical Networks (PON). AONs use a point-to-point network architecture, and there is a dedicated optical fiber line between each end user and the data center. In other words, in the process of signal transmission, there are switching devices like routers and active optical devices on the way from the data center to the end user. That is, AONs use active, electrically powered devices to direct the signal to the relevant user. Compared with AONs, PONs use a point-to-multipoint network architecture. PON uses optical splitters, which require no electrical power, to send the signal to each user. Since the optical splitters have the characteristic of bidirectional transmission, one Optical Line Terminal (OLT) can broadcast the signals to multiple Optical network units (ONUs). In addition, PON has various technical standards such as ATM-PON, Ethernet-PON, Gigabit-PON, based on different transmission protocols.
In the AONs, users have a dedicated optical fiber network, which is relatively easy for network maintenance, capacity expansion, and network upgrades. However, the AONs mainly use active devices to transmit optical signals. On the other hand, the PONs use passive components that can process the signals without power consumption. Since that, the cost of the maintenance of the PONs is much lower than that of the AONs. Other than that, the PON system has much advantages such as saving the fiber optic cable resources, realizing bandwidth sharing, and having a fast network deployment.
Both AON system and PON system are widely used now. However, with the popularity of the PON system, users tend to transfer the system from AON to PON system. When it comes to transfer change the system, it will be costly both in time and money because the whole entity system network architecture will need to be rebuilt. So that, how to reduce either time or money consumption during the period of system transformation become a problem to be solved.
