What This Product DoesTL-FC311B-20 is a gigabit media converter, providing a gigabit RJ-45 port and a gigabit SC fiber port, which can convert between electrical and optical signals. And long-distance data transmission through optical fiber can be applied to commercial scenarios such as park security monitoring and wireless networking.How This Product WorksTL-FC311B-20 adopts WDM (wavelength division multiplexing) technology, helping send and receive data at a distance of up to 20 km with only a single mode fiber, which saves half of the cable deployment cost for customers. TL-FC311B-20 transmits data at 1310 nm wavelength and receives data at 1550 nm wavelength on optical fiber. Therefore, the terminal device used in conjunction with the TL-FC311B-20 should send data at a wavelength of 1550 nm and receive data at a wavelength of 1310 nm. TP-Link another media converter TL-FC311A-20 is one of the products that can cooperate with TL-FC311B-20.Other FeaturesBesides, this media converter can be used as a standalone device (no rack required) or used with TP-Link's TL-FC1420 rack for auto MDI/MDI-X in TX port in which duplex mode is automatically negotiated.

Industrial-Grade Extender Connects Your Computer to a USB Device up to 150-ft. (45.7 m) AwayThis plug-and-play extender kit with heavy-duty all-metal housings is ideal for connecting your office computer's USB-A port to a printer, 1080p webcam, external hard drive or other USB device located up to 150-ft. (45.7 m) (45 meters) away. The B203-101-IND includes a local transmitter and a remote receiver that extends USB 2.0 signals over user-supplied Cat5/6 cabling (such as N202-Series Cat6 Ethernet cables).Protects Your Devices against Electrostatic Discharge (ESD)Machines on the shop floor can generate electrostatic discharges, wiping out data and damaging sensitive electronics. This extender kit provides ESD protection to ±15 kV, reducing potential static damage to your connected USB peripherals. The durable metal transmitter and receiver units withstand harsh physical conditions in industrial and commercial applications, such as factories, construction sites, supply rooms and warehouses.With Great Distance Comes Great FlexibilityBy extending the USB connection beyond the standard 16-foot distance limitation to 150-ft. (45.7 m), the B203-101-IND provides workstation flexibility to place your computer and the USB device where they are best suited. This extender kit supports USB 2.0 data transfer rates up to 480 Mbps and is backward compatible with USB 1.1 technology, allowing you to connect legacy devices. No network connectivity is needed.Plug-and-Play Kit Offers Flexible Power and Installation OptionsWith user-supplied USB cables, connect the transmitter to your computer and the receiver to your USB peripheral. Connect the transmitter and receiver with a user-supplied Cat5/6 cable (all cables sold separately). The extender kit requires no software to download and install. The metal chassis rest easily on any flat surface or mount to a wall or DIN rail using the included hardware. A power supply with international plug adapters as well as a RS-232 Phoenix adapter supporting a DC voltage range from 9-36V is included for connecting external power to the unit as needed.TAA-Compliant for GSA Schedule PurchasesThe B203-101-IND is compliant with the Federal Trade Agreements Act (TAA), which makes it eligible for GSA (General Services Administration) Schedule and other federal procurement contracts.

Power & ValueThe D-Link DGS-1250 Series Smart Managed Switches deliver real value as an Enterprise Access and Small-to-Medium Business (SMB) Access/Aggregation solution. They provide a range of physical interfaces (including a Console Port w/full CLI), multiple management interfaces, 11 Web languages, QoS enablement, and Advanced Layer-2 w/Lite Layer-3 features.The DGS-1250 Series switches support 24 or 48 x 10/100/1000BASE-T ports, with each switch also supporting an additional 4 x 10G SFP+ ports for optical connections using multimode or single-mode SFP transceivers – enabling real network horsepower at a value price.Easy Maintenance, Less DowntimeThe DGS-1250 Series supports Dual Image and Dual Configuration functionality, as well as a Console Port, all of which make it easier to configure, troubleshoot, and make other changes without interfering with network operation, while full Command Line Interface (CLI) functionality enables remote configuration, without the need for the Internet. And if a network issue ever does occur, the supported Spanning Tree Protocols (STP/RSTP/MSTP) help keep things running without interruptions or downtime.Automatic ConfigurationThe DGS-1250 Series supports Auto Voice VLAN and Surveillance Mode, which allow Voice and Video traffic to be automatically identified and handled differently from regular network traffic. Auto Voice VLAN detects Voice over IP (VoIP) traffic and automatically segments it from the rest of the network, increasing security and allowing Quality of Service (QoS) to be applied.Extensive Management and Advanced FeaturesThe DGS-1250 Series comes equipped with IGMP snooping, Port Mirroring, Spanning Tree Protocol (STP), and Link Aggregation Control Protocol (LACP). The IEEE 802.3x Flow Control function allows servers to directly connect to the switch for fast, reliable data transfers.The series also supports advanced features such as Static Routing, which allows for communication between different user groups in different VLAN segments in a network. And, because the switches can manage internal routing, the network router can be assigned to handle external traffic.Management VersatilityThe DGS-1250 Series comes with the D-Link Network Assistant (DNA) utility so admins can remotely control their network to the port level. DNA allows customers to easily discover multiple D-Link Smart Managed Switches within the same L2 network segment and display them onscreen for instant access.
