The Features And Remarks With Gigabit Interface Converter(GBIC)

Posted on by

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.

Features:

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.

Remarks:

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.

The Laser Safety And Warning With Cisco SFP Modules

Posted on by

Cisco SFP is also hot plugable, this make it easy to change and easy for maintenance compared with traditional modules. SFP fiber transceiver modules make the fiber optic network or fiber-Ethernet network easier to upgrade or maintain, users can replace a single SFP module during the process instead of replace the whole board with many modules on it.

SFP(Small form-factor pluggable) is a compact optical transceiver used in optical communications for both telecommunication and data communications applications. Cisco Transceiver Modules support Ethernet, Sonet/SDH and Fibre Channel applications across all Cisco switching and routing platforms. Cisco pluggable transceivers offer a convenient and cost effective solution for the adoption in data center, campus, metropolitan area access and ring networks, and storage area networks. Cisco portfolio of hot pluggable interfaces offers a rich set of choices in terms of speeds, protocols, reaches and supported transmission media.

Cisco SFP can be regarded as the upgrade version gbic module, SFP is short for Small Form-factor Pluggables, unlike GBIC with SC fiber optic interfaces is with LC interface and the main body size of SFP is only about half of GBIC, which makes SFP space saving. Signal transmitting rate of these modules range from 100Mbps up to 4Gbps or more, working distance of these SFP transceiver modules can be from 500 meters to 100 kilo meters, working wavelength of different SFP modules are typically 850nm, 1310nm and 1550nm, there are also CWDM type SFP transceivers available.

Laser Safety

Before you install SFP modules in a Cisco device or attempt to operate or service a Cisco device equipped with SFP modules, you must read and observe the important safety information in this article. Refer to the Regulatory Compliance and Safety Information publication or the Site Preparation and Safety Guide that supports your Cisco device for the complete list of translated safety warnings and agency approvals that apply to your Cisco device.

The Cisco SFP Transceiver Modules are equipped with a Class 1 Laser, which emits invisible radiation. Do not stare into open optical ports. These warnings apply to the cisco sfp modules.

Warning
  • 1,Class 1 laser product.
  • 2,Because invisible laser radiation can be emitted from the aperture of the port when no fiber is connected, avoid exposure to laser radiation and do not stare into open apertures.
  • 3,Laser radiation is present when the system is open and interlocks bypassed.
  • 4,Only trained and qualified personnel should be allowed to install, replace, or service this equipment.
