The Features And Remarks With Gigabit Interface Converter(GBIC)

GBIC transceiver is short name for the Gigabit Interface Converter, it is a media conversion device between Gigabit Ethernet and fiber optic networks, From this single device, connections can be made using single- or multi-mode fiber optic ports as well as copper wiring. It is possible to benefit from it in many point-to-point communications applications that involve interconnecting components and exchanging data between Ethernet and fiber optic networks. Via the GBIC transceiver, Gigabit network equipment can directly connect to copper wires, single mode fiber ports or multimode fiber ports.


The GBIC design can be used for hot-swap. GBIC is interchangeable products meet international standards. Gigabit switch with GBIC interface designed interchangeable flexible, account for a large market share in the market.GBIC Series product specifications are complete, including 850nm, 1310nm, 1550nm ,1470-1610nm four series. Requirements, all products have been rigorously tested, fully meet the IEEE 802.3z and GBIC-rev-5.5 standard, the performance targets were met or exceeded standards compatible with Gigabit Switch companies can use the Cisco whole series of switches and 3COM, INTEL, ALCATEL, AVAYA, EXTREME brand switches and other switches comply with GBIC specification.

GBIC transceiver as a function of the input / output transceivers. Its one end is inserted into the Gigabit Ethernet ports, such as port network switching equipment. On the other end, connected to said transceiver to the optical fiber network, usually through an optical fiber jumper. The apparatus characterized by the features, such as wavelength, it can be processed, and how quickly and efficiently transmit data, the power needs to operate, and the distance it can transmit data. These are the main factors to consider when purchasing a GBIC transceivers, to ensure that it meets the requirements of network performance.

The GBIC has become a standard form factor optical transceivers, and can support a variety of physical media, from traditional copper long-wave single-mode optical fiber length of several hundred kilometers. GBIC is an attractive, because of its flexibility, the standard network equipment. The various optical technology deployed in the network, IT personnel can purchase gbic module requires a specific type of link. The GBIC standard drive flexibility to reduce costs and provide greater flexibility for IT administrators. The GBIC standard non-proprietary and SFF-8053i files defined by the SFF Committee.


When install the GBIC modules, please note at the alignment groove at the side of the transceiver, and make sure it fit for the Ethernet interface slot and try the insertion, sometimes you may need to turn it 180 degree to fit for the interface.

Although GBIC fiber optic transceiver modules are plug and play, we strongly suggest you disconnect all the fiber optic patch cords connected to it before you install or remove it.

Relationship Between The Coupler And Splitter

Relationship between the coupler and splitter:In fact, splitter is named for the function of the device, coulper named for its working principle, splitter may be based coupler, and may be based on the waveguide or the separating element, coupler can be done either the splitter, but also can be done WDM, attenuator.


Fiber optic couplers either split optical signals into multiple paths or combine multiple signals on one path. Optical signals are more complex than electrical signals, making optical couplers trickier to design than their electrical counterparts. Like electrical currents, a flow of signal carriers, in this case photons, comprise the optical signal. However, an optical signal does not flow through the receiver to the ground. Rather, at the receiver, a detector absorbs the signal flow. Multiple receivers, connected in a series, would receive no signal past the first receiver which would absorb the entire signal. Thus, multiple parallel optical output ports must divide the signal between the ports, reducing its magnitude. The number of input and output ports, expressed as an N x M configuration, characterizes a coupler. The letter N represents the number of input fibers, and M represents the number of output fibers. Fused couplers can be made in any configuration, but they commonly use multiples of two (2 x 2, 4 x 4, 8 x 8, etc.).


Fiber optic splitter is a device that split the fiber optic light into several parts by a certain ratio. The simplest couplers are fiber optic splitters. These devices possess at least three ports but may have more than 32 for more complex devices.Fiber optic splitters are important passive components used in FTTX networks. But two kinds of fiber splitters are popular used, one is the traditional fused type fiber optic splitter (FBT splitter), which features competitive prices; the other is PLC fiber optic splitter, which is compact size and suit for density applications. Both of them have its advantages to suit for different requirement.

Fiber optic splitter typical parameter include input and output part cable length, splitting ratio, working wavelength and with what kind of fiber optic connectors. Just like fiber patch cable, fiber splitters are usually with 0.9mm, 2mm or 3mm cables. 0.9mm outer diameter cable is mostly used in stainless steel tube package fiber optic splitters, while 2mm and 3mm cables are mostly used in box type package fiber splitters. Based on working wavelength difference there are single window and dual window fiber optic splitters. And there are single mode fiber splitter and multimode fiber splitter. Typical connectors installed on the fiber optic splitters are FC or SC type.

Fiber optic couplers or splitters are available in a selection of styles and sizes to separate or combine light with minimal loss. All couplers are produced employing a proprietary procedure that produces reliable, low-cost devices. They’re rugged and impervious to common high operating temperatures. Couplers can be fabricated with custom fiber lengths or with terminations of any type.
