Three Main Types of SFP Transceiver

SFP stands for “Three Main Types of SFP Transceiver” and transceiver means a device that can both transmit and receive data. This article “Three Aspects You Should Know About SFP Transceiver” is intended to describe all about SFP transceivers in detail that could help network professionals understand about SFP optics and its types.

 

What Is SFP Transceiver

 SFP is a new generation of fiber optic module transceivers, known for its compact size, flexibility and high level of performance. It is specified by MSA (Multisource Agreement) and it is available with a variety of transmitter and receiver types, allowing users to select the appropriate transceiver for each link to provide the required optical reach over the available optical fiber type. SFP transceiver is generally with two ports, one is TX port which is used to transmit the signal, and the other one is RX port which is used to receive signals.

 

Features of SFP Transceiver

SFP transceivers are used in network switches, firewalls, routers, and network interface cards. SFPs are also used in storage interface cards or fiber channel storage switches, supporting different speeds such as 2Gb, 4Gb, and 8Gb. SFP transceivers comply with the Multi Source Agreement between different manufacturers. Optical SFP transceivers come with digital monitoring features with the help of which one can monitor the performance of SFP in real time. This feature can be used to monitor SFP’s performance parameters like working temperature and wavelength, supply voltage, optical input and output etc. These transceivers have a PCB in them which connects to an electrical connector designed for SFP. SFP transceiver also has a 256 byte EEPROM memory. SFP transceivers are housed in a metal enclosure and their power dissipation is low. They operate over a wide temperature range and support a large number of different types of cable. An improved version of SFP standard called SFP+ can support transmission rates up to 10Gbps.

 

Types of SFP Transceiver

  • CWDM SFP

The CWDM SFP (small form-factor pluggable) transceiver is really a compact optical transceiver used in optical communications for both telecommunication and data communications applications on the wavelength. CWDM SFP are used to link the ports to the fiber optic network, typical CWDM SFP like Cisco’s could support both Gigabit Ethernet and Fiber Channel. CWDM SFP transceiver modules make use of the SFP interface for connecting the equipment and use dual LC PC fiber connector interface for connecting the optical network. Gigalight CWDM SFP transceivers can be found with a variety of different transmitter and receiver types, allowing users to decide on the appropriate transceiver for each link to provide the required optical reach over the available optical fiber.

  • DWDM SFP

The Dense Wavelength-Division Multiplexing (DWDM) transceivers offer DWDM transport with dramatically lower power and cost in a standard pluggable SFP package. Gigalight DWDM SFP is available in all 100 GHz C/L-band wavelengths on the DWDM ITU grid. As multirate interfaces they support any protocol from 100 Mbps to 4.25 Gbps. The modules meet the requirements of the IEEE802.3 Gigabit Ethernet standard and ANSI Fiber Channel specifications, they are suitable for interconnections in Gigabit Ethernet and Fiber Channel environments. The DWDM SFP is designed to accept DWDM SONET/SDH (with or without FEC) for 200km links and Ethernet/Fiber Channel protocol traffic for 80km links.

  • 10G SFP

The 10G SFP Transceiver Modules refers to 10G SFP Plus Transceivers,someone know that the sfp+ is an enhanced version of the SFP that supports data rates up to 10 Gbit/s. Several standards for 10G SFP has been released, 10GBase-SR is for OM3 multimode optical fiber, relevant SFP plus working distance 300 meters max, 10GBase-LR is for single mode optical fiber, relevant SFP plus working distance 10km, 10GBase-LRM is for FDDI multimode fiber, the SFP plus working distance 220 meters.
