There are numerous types of transceivers available that can be used in a variety of applications including radio applications and telecommunications applications. Different specifications and designs are employed to meet the changing needs of designers. This article will introduce three primary types of transceivers used in today’s telecommunication systems.

SFP Transceiver

The small form-factor pluggable (SFP) is a compact and hot-pluggable transceiver used for both telecommunication and data communications applications. The form factor and electrical interface are specified by a multi-source agreement (MSA). It interfaces a network device motherboard (for a switch, router, media converter or similar device) to a fiber optic or copper networking cable. SFP was one of the most popular versions of transceivers until the enhanced version was introduced. Select the SFP devices for the best results.

Fiberstore’s SFP transceivers are available for designers to use in a variety of applications. These transceivers come in a variety of transmitter and receiver types. Users can select an appropriate transceiver by reviewing several different categories. Some common categories include: copper and fiber, single-mode and multi-mode, SX (transmits up to 550m at 1.25 Gb/s), LX (transmits up to 10 km), and BX (transmits up to 10 km). For example, HP J8177C compatible 1000BASE-T SFP copper transceiver is high performance and cost-effective transceiver for 100m distance over Cat 5 UTP cable.

SFP+ Transceiver

The enhanced small form-factor pluggable (SFP+) is an enhanced version of SFP and is designed to support data rates up to 10 Gbit/s. SFP+ was designed to have higher port density compared to SFP. The SFP+ specification was first published on May 9, 2006, and version 4.1 published on July 6, 2009. SFP+ supports 8Gbit/s Fiber Channel, 10 Gigabit Ethernet and Optical Transport Network standard OTU2. The SFP+ product family includes cages, connectors, and copper cable assemblies. The SFP+ transceiver modules are specified for 8Gbps/10Gbps/16Gbps Fiber Channel and 10-Gigabit Ethernet applications. In addition, they have the ability to connect to a variety of different types of optical fiber and are highly flexible. That’s why they are so desirable to designers.

XFP Transceiver

XFP transceiver is a hot-pluggable and protocol-independent 10 Gbit/s optical transceiver designed to help drive cost and power consumption out of 10 Gbit/s optical networking applications. This particular XFP specification was developed by the XFP Multi-Source Agreement Group. XFP transceivers are capable of operating at wavelengths of 850 nm, 1310 nm, and 1550 nm. They are capable of operating at a single wavelength or through the use of dense wavelength-division multiplexing techniques.

There are a variety of transceiver types available, but the most popular ones include: SR (850 nm and can transmit up to 300 m), LR, ER, and ZR. LR is 1310 nm and can transmit distances up to 10 km. For example, Juniper XFP-10G-L-OC192-SR1 compatible 10GBASE-LR XFP transceiver from Fiberstore operates at a wavelength of 1310 nm at up to 10km links. ER is characterized by 1550 nm and can transmit distances of 40 km. ZR can transmit distances up to 80 km. Designers prefer to use XFP packaging because it has a smaller footprint than other devices.

Choose the Best Transceiver for Your Design

There are also other types of transceivers apart from the above-mentioned. Since there are so many types of transceivers, try to find the best transceiver for your design and applications. When the design is optimized, everything seems to fall into place for the end user. The reliability of your design will improve, and your end-user will reap the benefits of a system that will stand the test of time and the rigors of a stressful environment.
