Fiber optical ethernet Switch with 2 * 10/100/1000M SFP slots + 4 * 10/100/1000M gigabit RJ45 ports
Support flow control
In data communications, flow control is the process of managing the rate of data transmission between two nodes to prevent a fast sender from overwhelming a slow receiver. It provides a mechanism for the receiver to control the transmission speed,
Flow control should be distinguished from congestion control
so that the receiving node is not overwhelmed with data from transmitting node. Flow control should be distinguished from congestion control, which is used for controlling the flow of data when congestion has actually occurred.Flow control mechanisms can be classified by whether or not the receiving node sends feedback to the sending node.
Flow control is important
Flow control is important because it is possible for a sending computer to transmit information at a faster rate than the destination computer can receive and process it. This can happen if the receiving computers have a heavy traffic load in comparison to the sending computer, or if the receiving computer has less processing power than the sending computer.
Overview
10/100/1000M Ethernet Optical Fiber Switch is with four 10/100/1000M UTP ports and two 1000M SFP/SC/FC/ST Fiber ports. The end users can use different optical module according to his requirement, for example: 1000Base-T, 1000Base-SX, 1000Base-LX etc.
Features
1. 4*RJ45 ports and 2*optical sockets, convert Optical-Electric Ethernet signals between 10/100/1000M UTP ports and 1000M optical fiber ports;
2. Switch Ethernet signals between port and port;
3. Supports Auto MDI / MDI-X function;
4. Supporting the transmission of extra-long VLAN packets;
5. Flow control for full duplex and half duplex;
6. All optical module brands are supported; if SFP type, support hot-plug supported.
