There are numerous of small form pluggable optical modules and
network accessories to select from available on the market. Most optic
modules normally work to both emit and receive electronic optical
signals. All of these module transceiver form-factors are made beneath
the Multi-Source Agreement. Industry professionals ensure that modules
are created under this strict Agreement. All optical transceivers are
put 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 continue to work best
for you. Now, Fiberstore develop detail of SFP Transceiver Module,and you also ensure it is best for you.
The principle of SFP optical module
SFP
Transceiver Modules - hot-pluggable module, the greatest rate up to
10G, multi-use LC interfaces. SFP(small form pluggable) can be
understood since the upgrade version of GBIC. SFP module volume ratio
reduced by half than GBIC module, the identical panel
could be configured in additional than double of ports. Other functions
of SFP Module are do i think the GBIC basicly . Items like Cisco SFP Modules(cisco mini gbic)
tend to be smaller and so are just about half the dimensions of GBIC
optics. These modules send speeds that range between 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 all the receiver ROSSA)and board IC and
external components.External accessories are housing, base, PCBA, pull
rings, clasps, unlock, rubber stopper composition. For simple to
identify ,usually the form of module of recognize along with pull ring
parameters.
The means of SFP classification
Divided
by rate :155M/622M/1.25G/2.125G/4.25G/8G/10G,155M and 1.25G market is
used more, 10G technologies are maturing, demand is always to increase
quickly.
Divided according to 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 , and the transmission distance is more than 2KM.
850nm/1310nm/1550nm price relatively less expensive than another three.
The
bare module is straightforward to confuse should they have no mark,the
makers is likely to make the colour of pull ring to distinguish
generally, as an example: black pull ring is multi-mode, the wavelength
is 850nm; blue may be the 1310nm module; yellow is the 1550nm module ;
purple is the 1490nm module and so on.
