Informations about PIC Network Interface Cards

Network interface card is the full name of NIC, also known as a network adapter, LAN adapter. It is a computer hardware being used to connect the computers to the networks by preparing, sending, and controlling data on the network. FiberStore provides PCI/PIC-Express 100M, 1000M and 10G fiber optic network cards, they are available in both multimode and single mode configurations with ST, SC, MTRJ, or LC connectors, and SFP for Gigabit.

Network Interface Cards
As we know from the Wikipedia, a network interface card, known as Fiber Optic Network Interface Card, which is simply a computer circuit board or card that is installed in a computer so that to connect to the network. Personal computers and workstations on a local area network (LAN) typically contain a network interface card specifically designed for the LAN transmission technology, such as Ethernet or token ring. NIC adapter hardware is the form factor os an add-in card such as PCI card.

NIC cards work with wired or wireless connection, as they support either wired Ethernet or Wifi wireless standards. Ethernet NICs plug into the system bus of the PC an include jackets for network cables, while WiFi NICs contain built-in transmitters/receivers. In most computer nowadays, many NICs are pre-installed by the manufacturer. They features a speed rating such as 11 Mbps, 54 Mbps or 100 Mbps that suggest the general performance of the unit.

PCI and PCI Express
PCI is short for Peripheral Component Interconnect. It is regarded as a local computer bus for attaching hardware device in a computer. PCI is part of local bus standard. The PCI bus supports the functions found on a process bus but in as standardized format that is independent of any particular processor’s native bus. PCI has been a versatile, functional way to connect sound, video and network cards to a motherboard.

As processors, video cards, sounds cards and network has gotten faster and more powerful, the shortcoming of PIC appears. Because PCI has a fixed width of 32 bits and can handle only 5 devices at a time. To overcome these shortcomings, the PCI Express appears with improvements over the old PIC, including higher maximum system bus throughput, lower I/O pin count and smaller physical footprint, better performance-scaling for bus devices, a more detailed error detection and reporting mechanism and native hot-plug functionality.

A key difference between PCI Express bus and older PCI is the bus topology. PCI uses a shard parrel bus architecture, where the PCI host and all devices share a common set of address/data/control lines. In contrast, PCI Express is based on point to point topology, withe separate serial links connecting every device to the root complex.

Gigabit PCI Express Network Card
Gigabit PCI Express network card is gigabit based network adapter card that offers a versatile solution that allows servers and desktop PCs to connect to a Gigabit network through a PCI-E slot.

TDM and WDM Technologies Introduction

Current increasing in the demand for high speed network and higher bandwidth has motivated the development of the ultra-broadband systems based on photonic networking technologies. Optical time division multiplexing (TDM) and wavelength division multiplexing (WDM) are two main solutions to cater for this demand, because the wide bandwidth of photonic components combined with the flexibility of TDM and WDM routing technologies, and the high speed capabilities of optical devices, which includes optical switches, optical gates, opitcal wavelength conversion equipment, etc. to offer the potential speed of several Terabits per seconds for switched networks. This article is aimed to introducing characteristics and WDM and TDM, as present a comparision on between them.

TDM is used to transmit a wide variety of signals, including HDMI, DVI, 3G-SDI, RGB, HD and SD component video, S-video, composite, USB, audio and RS-232 control. Time Division Multiplexing is a method of carrying multiple signal over the same channel and each signal periodically getting the entire bandwidth for a short duration. In the TDM network, a specialized circuit, called serializer, allocates parallel input streams into time slots in the series output. The serial bit stream is transmitted as a single wavelength down a fiber optical cable On the far end of the channel, a deserializer reconstructs the original parallel signal from the serial bit streams. The serial data rate must be sufficiently fast to ensure no data is missed. Fiber optic transmitters and receivers for high resolution AV signals typically operates at 4-6 Gbps data rate.

Wavelength-division multiplexing (WDM) is based on frequency division multiplexing or FDM. It multiplex a number of optical carrier signals onto a single optical fiber utilizing different
wavelengths of laser light. Each wavelength can carry a different signals that is independent of other wavelengths. The WDM transmitter and receivers enables transmission of an HDMI/DVI signal over fiber optical cable. The transmitter have five inputs and one output. Each inpu has its own E-to-O converter with a laser diode that operates at a unique wavelength. A special devices named a WDM multiplexer/De-multiplexer combines the various wavelengths for transmission down a fiber optic cable.

A WDM system can transmit bidirectional signals over a single fiber using a unique wavelength for the the return data. While In a TDM system, single wavelength transmission is unidirectional. To achieve the bidirectional transmission, another fiber is needed. A popular device used in multimode WDM HDMI and DVI extenders has a specified maximum instance around 300 meters (984 feet) before the skew exceeds 1.78 ns. The same device can operate up to 400 meters (1,312 feet) for an HDMI or DVI signal with a 165 MHz pixel clock to allow a maximum skew of 2.42 ns.

A TDM system transmits the fiber optic signal at a single wavelength, such that the entire signal propagates at the same speed. A well-managed loss budget and use of high-bandwidth, laser-optimized OM4 fiber enables multimode TDM systems to achieve distances up to 2 km (6,561 feet), as shown in Figure 6. As a result, TDM systems achieve much greater transmission distances than WDM systems used for AV signal extension. Singlemode systems use long wavelengths around 1310 nm or 1550 nm. At these wavelengths, WDM systems experience less inter-channel skew to achieve longer transmission distances. A typical WDM single-mode system for HDMI/DVI signals transmits up to 12 km (7.5 miles), compared to 30 km (18.75 miles) for a TDM single-mode system.

Daisy-chaining allows a signal to be delivered to multiple destinations without the need for routing or distribution equipment, or multiple transmitters. An AV signal from a single transmitter, or from a single output on a matrix switcher, is sent to a receiver with daisy-chain capability. The receiver providers a loop-out signal that is sent to the next receiver in the daisy-chain. In a TDM system, the second fiber used for bidirectional communications is often available as a loop out for creating a daisy-chain configuration. Since there is a single bit streams, requiring multiple optical converters and an additional WDM multiplexer/demultiplexer to implement a loop-through. As a result, a WDM receiver typically has only a single fiber connection, and cannot be connected in a daisy-chain configuration.

A high speed digital matrix switcher in a TDM system operates efficiently, typically using less power than a WDM matrix switcher. The efficient design also let a TDM matrix switcher to occupy less rack space. Like the picture which is Extron FOX Matrix 14400 144x144 fiber optic matrix switcher that occupies eight rack units. It is compatible with the complete family of FOX Series transmitters and receivers to supports HDCP-compliant HDMI, DVI, 3G-SDI, RGB, HD/SD component, S-video, composite video, USB, stereo audio, and RS-232 control signals. A matrix board is also available to provide local 3G-SDI signals.
