Why SFP Transceivers Are Widely Used In Communication

SFP transceivers (small form-factor pluggable) are modules act to connect the electrical circuitry of the module with the optical or copper network, widely used for both telecommunication and data communications applications. The SFP transceiver is not standardized by any official standards body, but rather is specified by a multi-source agreement (MSA) between competing manufacturers.
 Advantages The SFP was designed after the GBIC interface, and allows greater port density (number of transceivers per cm along the edge of a mother board) than the GBIC, which is why SFP is also known as mini-GBIC.

 SFP transceivers are expected to perform at data speeds of up to five gigabits per second (5 Gbps), and possibly higher. Because SFP modules can be easily interchanged, electro-optical or fiber optic networks can be upgraded and maintained more conveniently than has been the case with traditional soldered-in modules. Rather than replacing an entire circuit board containing several soldered-in modules, a single module can be removed and replaced for repair or upgrading. This can result in a substantial cost savings, both in maintenance and in upgrading efforts.
 Types SFP transceiver  have a wide range of detachable interfaces to multimode/single-mode fiber optics, which allows users to select the appropriate transceiver according to the required optical range for the network. SFP transceivers are different types working with different wavelength for various kinds of distances. 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. For example, 1000BASE-SX SFP  use 850nm for max 550 meters, LX SFP use 1310nm for max 10km, ZX SFP could reach 80km.
 There are also copper SFP transceivers with copper cable interfaces, which allow a host device designed primarily for optical fiber communications to also communicate over unshielded twisted pair networking cables. Modern optical SFP transceivers support digital diagnostics monitoring (DDM) functions, also known as digital optical monitoring (DOM). This feature gives users the ability to monitor the real-time parameters of SFP, such as optical output power, optical input power, temperature, laser-bias current and transceiver supply voltage. DOM function for SFP is optional, it help users detect real time SFP working status.
 Applications SFP interfaces a network device motherboard (for a switch, router, media converter or similar device) to a fiber optic or copper networking cable. SFP transceivers support communications standards including SONET, Gigabit Ethernet, Fiber Channel and other communications standards. They also allow the transport of fast Ethernet and gigabit Ethernet LAN packets over time-division-multiplexing-based WANs, as well as the transmission of E1/T1 streams over packet-switched networks.

Three Point To Understand The SFP Modules

There is number 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 to ensure that modules are created under this strict agreement. All optical transceivers are made available for 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 collaborate 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+ LR transceiver (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 addition than double of ports. Other functions of SFP module are done 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 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 housed, 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 markets 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.

Availability of new tunable DWDM SFP+ pluggable transceivers

Optical module supplier fiberstore has announced the general availability of new tunable DWDM SFP+ pluggable transceivers, uTune Director support, and SFP+ Next Day Dense Wave (NDDW) DWDM optical transceivers. The company says the tunable optical modules can enable operators of telecom, datacom, and enterprise 1GB DWDM transceiver networks to significantly reduce sparing costs, improve operational efficiency, and turn up new customers or circuits more quickly than with conventional fixed-wavelength transceivers.
The company supplies the MSA-compliant tunable 1000BASE-T SFP module  for support of distances up to 80 km. The transceivers can be tuned to any of 102 standard ITU channels, at C-band 50-GHz spacing. They are available in both linear and limiting electrical interfaces (1.65 W max – limiting version) and carry a five-year warranty.
Fiberstore uTune Director, a standalone device, enables end users to select any DWDM channel for each tunable SFP transceiver , tune it, and set it as a fixed channel on demand. Meanwhile, the Next Day Dense Wave initiative is designed to eliminate the typical 8 to 12 week lead time for DWDM components.

"We are excited to continue our track record of providing the industry with innovative solutions that solve real-world problems. With our new portfolio of tunable SFP+ products, our customers’ ROI will be measured in weeks or months – not years," said Young Mandy.

Benefits Of Sfp+ Transceiver And Dwdm

One of the main benefits of fiber optic transceiver  is that it offers a large number of ports per card for a 10-Gbit/sec light transceiver unit. Considering thermal factors, each one of the board would provide maximum ports. In comparison to Gigabit optical Ethernet transceiver module, this transceiver module offers higher port density.
The next advantage of using the SFP+ transceiver is its potential for reducing costs without affecting relative performance. It offers cost reduction due to two factors. The first is the smaller area that eliminates the need for more amount of costly silicon, and the second is that the basic design helps reduce costs of production. Thus, one can have an inexpensive but high-end GB Ethernet transceiver. In fact, the costs are even lower than X2, XFP and XENPAK.
These Transceivers have more compact form compared to XFP and X2, and they can be connected directly with similar type X2, XFP,1000BASE-T SFP module and XENPAK. The transceiver complies with the protocols SFF-8432, SFF-8431 and IEEE802.3ae, and it is a mainstream design.
Dense Wavelength Division Multiplexing or DWDM technology is used for increasing fiber optics capacity resulting in faster data transfers. It would take multiple signals and transmits them forward at different wavelengths concurrently through one fiber. This helps in making the most out of a single fiber, transforming it virtually into several fibers. Currently, the fastest data transmission from the technology has been found to be 400 GB per second.
It can be used for sending 80 wavelengths simultaneously. This means that the technology can be used for converting 1 GB per second capacity into 80 GB per second transmission.
The faster data transfer capabilities of DWDM offer benefits for SONET, ATM and IP transfers. This would help computer systems to operate networks faster and better, overall. This growth in efficiency helps increase data transmission speed at a dramatic level.
The next advantage of the technology is that it avoids the need for laying new fiber because it can help make the most out of the existing fiber. Due to this reason, the technology is not just more convenient but more financially beneficial because laying down new fiber can dramatically increase the costs.
The development of the technology has helped dramatically increase transmission capacity. it is helpful in increasing wavelengths by 2 to 3 times by suppliers. There is no need for improving or restoring the fibers already laid down because it is possible to upgrade links simply through upgrading or reorganizing.

The DWDM fiber network delivers the essential infrastructure required for supporting current and future technologies by offering unlimited bandwidth capacity. The integrated resources offered would help in meeting the ever-increasing telecommunication needs. Thus, the new technologies in the form of the Transceivers and higher-capacity fiber networks enable the telecommunications and other industries to keep up with the ever-increasing demands.
