A Brief Introduction to SFP in the Fiber Telecom Industry

Abbreviates Small Form Pluggable, SFP is a hot pluggable fibre transceiver. SFP stands for Small Form-factor Pluggable is a hot-pluggable fibre transceiver. The mechanical, electronic, and optical design and performance are based on a Multisource Agreement (MSA) in the fibre telecom industry.

The MSA is an agreement among fibre optic industry leaders including Agilent, IBM, Lucent, Infineon, Tyco, Molex, Finisar, etc. The requirement is maintained by the SFP committee.

SFP requirement is compliant with GR-253-CORE, ITU-T G.957, SFF-8472, etc. It offers a fully standard compliant interface amid the photonic layer & the electrical layer.

The major parts in a transceiver include a FP laser; a PIN optical receiver with TIA built in, a post amplifier, a laser driver, and a microprocessor.

Where it’s employed?

SFP fibre optic transceivers are employed for both telecommunication & data communication. It connects a switch, router, PLC splitter or other network devices to a fibre cabling plant.

Transceivers have been manufactured for most of the fibre networking standards such as SDH/SONET, Ethernet, Fibre Channel, etc.

SFP can be discovered in metro access network, metro core network, Wide Area Networks, etc.

Types of SFP Transceiver:

In addition to supporting the fiber optic communication standards mentioned above, transceivers are available for all types of physical cabling: multimode fiber and single mode fiber, 850nm VCSEL, 1310nm and 1550nm laser, etc. Here lists just a few.

• 1000Base-SX
• 1000Base-LX/LH
• 1000Base-ZX
• CWDM SFP
• SFP+ 10G
• 1000Base-EX
• 1000Base-BX10
• Fibre Channel shortwave SFP

Advantages:

SFP transceiver is absolutely compliant with most networking standards like SONET, Fibre Channel etc. It has a Digital Diagnostic Monitoring Interface. It can also automatically control output power and extinction ratio over a wide temperature range to compensate for laser degradation.

SFP+ is an improved version of SFP and is intended for higher data rates, lower expenditure, and improved thermal performance.

In the world of IT, SFP means Small Form-Factor Pluggable. SFP modules are being added into the network switch in order to hook up it in the structure of fibre optic with the Ethernet system. The Cisco SFP transceivers are manufactured to change the serial electric signals to the serial optical signals which mainly sustain the Gigabit Ethernet, Fibre Channel and the Sonet/SDH where it provides a positive approach in acquiring a resolution for the process of adoption in university grounds, data hubs, metropolitan locations, ring networks and the storage network location.
