Fiber Optic Transceivers Effect

- Sep 04, 2017 -

Fiber optic transceivers, is a short distance twisted pair electrical signals and long distance optical signal interchangeable Ethernet transmission media conversion unit, in many places also known as the photoelectric converter. The product is generally used in the actual network environment where the Ethernet cable can not be covered and must be used to extend the transmission distance, and is usually located in the broadband layer network access layer applications; such as: monitoring security engineering high-definition video image transmission; Helping to connect the last mile of fiber to the metro network and the outer network also played a huge role.

Function: Fiber optic transceivers are generally used in Ethernet networks where Ethernet cables can not be covered and must be used to extend the transmission distance in the actual network environment while also helping to connect the last mile line of fiber to the metro and more outer networks A great effect. With fiber optic transceivers, but also for the need to upgrade the system from copper to fiber, for the lack of funds, manpower or time to provide users with a cheap program. The role of fiber optic transceivers, we want to send the electrical signal into optical signals, and sent out at the same time, can receive the optical signal into electrical signals, input to our receiver.

Advantage

Referred to fiber optic transceivers, people often can not help but will be fiber optic transceivers with optical switches to compare the following main talk about the advantages of fiber optic transceivers relative to the optical switch.

First of all, fiber optic transceivers plus ordinary switches in the price is much cheaper than the optical switch, in particular, some optical switch in the plug-in module will lose one or even several electrical ports, so that operators can make a large extent Reduce pre-investment.

Second, because most of the switch's optical modules are not uniform standards, so the optical module once the damage from the original manufacturers need to replace the same module, so that the late maintenance to bring a lot of trouble. But the fiber optic transceivers between different manufacturers of equipment in the interconnection between the no problem, so once the damage can also use other manufacturers to replace the product, it is easy to maintain.

Also, fiber optic transceivers are more complete than optical switches at transmission distances. Of course, optical switch in many ways also has advantages, such as unified management, unified power supply, etc., here is no longer discussed.

Connection method

The backbone backbone network is constructed by using SPANNING TREE to construct the backbone of the metro area. This structure can be deformed into a mesh structure, which is suitable for the high density central area on the metropolitan area network, forming a fault-tolerant core backbone network. Ring backbone network support for IEEE.1Q and ISL network features can guarantee compatibility with most mainstream backbone networks, such as cross-switch VLAN, TRUNK and other functions. Ring backbone network for the financial, government, education and other industries set up broadband virtual private network.

The chain-type backbone network can save a large number of backbone light quantity by chain connection, which is suitable for constructing high-bandwidth and low-cost backbone network at the edge of the city and the suburbs. The model can also be used for highway, oil and transmission Lines and other environments. Chain backbone network IEEE802.1Q and ISL network characteristics of the support, can guarantee compatible with the vast majority of the backbone network, for the financial, government, education and other industries set up broadband virtual private network. Chain backbone network is able to provide image, voice, data and real-time monitoring of integrated transmission of multimedia networks.

User access system using 10Mbps / 100Mbps adaptive and 10Mbps / 100Mbps automatic conversion function, you can connect any client device, without preparing a variety of fiber optic transceivers, the network can provide a smooth upgrade program. At the same time the use of half-duplex / full-duplex adaptive and half-duplex / full-duplex automatic conversion function, you can configure the user inexpensive half-duplex HUB, several times to reduce the cost of the client network, improve network operators The competitiveness of the.
