Three Point To Understand The SFP Modules

There are a number of small form pluggable optical modules and network accessories from which to choose on the market. Most optic modules normally attempt to both emit and receive electronic optical signals. All of those module transceiver form-factors are created underneath the Multi-Source Agreement. Industry professionals ensure that modules are created under this strict Agreement. All optical transceivers they fit into module sections by their speed rates of transmission. Each pluggable module supports rates from 1Gbps to 10Gbps. Each support rate will help choose which networking accessory will work good for you. Now, Fiberstore have detail of SFP Transceiver Module,and you makes it good for you.

The principle of SFP optical module

SFP Transceiver Modules - hot-pluggable module, the greatest rate as high as 10G, multi-use LC interfaces. SFP(small form pluggable) can easily be understood since the upgrade version of GBIC. SFP module volume ratio reduced by half than GBIC module, the identical panel can be configured in more than double of ports. Other features of SFP Module are do i think the GBIC basicly . Things like Cisco SFP Modules(cisco mini gbic) are usually smaller and therefore are just about half the dimensions of GBIC optics. These modules send speeds that vary from 100Mbps to about 4+Gbps. Their transmission length begins at approximately 500 meters and goes up to 120+ kilometers.

The composition of SFP optical module

Laser (includes transmitter TOSA with the receiver ROSSA)and board IC and external components.External accessories are housing, base, PCBA, pull rings, clasps, unlock, rubber stopper composition. For straightforward to recognize ,generally the type of module of understand along with pull ring parameters.

The method of SFP classification

Divided by rate :155M/622M/1.25G/2.125G/4.25G/8G/10G,155M and 1.25G companies are used more, 10G technologies are maturing, demand is always to increase quickly.

Divided based on the wavelength : 850nm/1310nm/1550nm/1490nm/1530nm/1610nm, the 850nm wavelength is SFP multimode , and the transmission distance is 2KM below .1310/1550nm is SFP single-mode , as well as the transmission distance is more than 2KM. 850nm/1310nm/1550nm price relatively cheaper than another three.

The bare module is easy to confuse if they have no mark,the manufacturers is likely to make the colour of pull ring to tell apart generally, for example: black pull ring is multi-mode, the wavelength is 850nm; blue is the 1310nm module; yellow will be the 1550nm module ; purple will be the 1490nm module and so forth.
