SFP Transceiver—an Important Role in 10G Ethernet

In order to meet the never-ending requirement for faster rates of data transmission, Ethernet technology has continually evolved since 1970s. 10 Gigabit Ethernet, which is a group of computer networking technologies for transmitting Ethernet frames at a rate of 10 gigabits per second (10×109 or 10 billion bits per second), becomes the ideal foundational technology for companies that want to upgrade their data centers to meet evolving business needs. To connect the cabling to the network, specific devices need to be taken into consideration. Transceivers provide the interface between the equipment sending and receiving data and the cabling transporting it. SFP transceivers are among the various transceivers available to 10 G Ethernet.

Why SFP Transceiver Plays an Important Role in 10 G Ethernet

There are four defined types of transceivers for 10 G Ethernet—XENPAK, XPAK, XFP and SFP+. XENPAK is the first 10 G pluggable transceiver on the market to support the 802.3ae standard transmission optics. Now it is thought to be overly large for high density applications. XPAK is mainly used in Network Interface Card (NIC) and Host Bus Adapter (HBA) markets for use in Servers and NAS devices. XFP is the newest pluggable transceiver on the market. It relies on a high-speed interface, high-priced serializer/deserializer (SERDES) which are expensive. Thus XFP adds an unacceptable cost to the base system. SFP+ transceiver is a 10 G optics using the gigabit SFP. It provides a flexible and cost-effective solution for enterprise networks, data centers, etc. Thus it is popular nowadays.

SFP Transceiver

SFP Transceiver is a small transceiver that plugs into the SFP port of a network switch and connects to fiber channel and Gigabit Ethernet (G) optical fiber cables at the other end. SFP Transceivers are widely used in CWDM system and DWCM system. DWDM SFP transceivers are based on the SFP form factor which is an MSA standard build. It has a specific tuned laser which emits a “color” which is defined in the DWDM ITU grid. There are many kinds SFP transceivers for the DWDM system in the market. DWDM SFP10G 58.98, which is among the various DWDM SFP transceivers, is designed to deploy in the DWDM networking equipment in metropolitan access and core networks. With a wavelength of 1558.98 nm, it is available in all C-Band Wavelengths on the 100GHz.

SFP+ Transceiver

SFP+ Transceivers, which are first published on May 9, 2006, are enhanced versions of the SFP transceiver that supports data rates up to 16 Gbit/s. They offer customers a wide variety of high-density. 10G SFP+ transceiver has been widely used for 10G Ethernet and other high speed transmissions with the rapid development of fiber optic technologies. 10G CWDM SFP+ transceiver, for example, is small form factor pluggable module for bi-directional serial optical data communications such as IEEE 802.3ae 10GBASE-LR/LW/ER/ZR. It can be used with single fiber CWDM system or dual fiber CWDM system. Cisco DWDM SFP+ transceiver is another type of SFP+ transceiver manufactured by Cisco. Supporting 10-Gigabit data rates from 9.9G to 11.1G to accommodate different applications, the Cisco DWDM SFP+ transceiver allows enterprises and service providers to provide scalable and easy-to-deploy 10-Gbps LAN, WAN, and optical transport network (OTN) services in their networks.

10 G functionality can provide immediate performance benefits and safeguard a company’s investment well into the future. To make full use of the 10 G Ethernet, the SFP transceiver plays an important role in connecting the cabling to the network. Fiberstore manufactures and supplies a complete range of optical transceiver modules which can be customized, including the aforesaid 10g CWDM SFP+, Cisco DWDM SFP+ and DWDM SFP10G 58.98.
