10GBASE-LR SFP+ Transceiver Overview

by www.fiber-mart.com

SFP+, an enhanced version of SFP (small form-factor pluggable), can support data rates of 10 Gbit/s. 10G SFP+ transceiver is a popular industry format supported by many network component vendors. It plays an important role in today's network applications. There are different types of SFP+ modules, like 10GBASE-SR SFP+ module, 10GBASE-LR SFP+ module, 10GBASE-LRM SFP+ module, 10GBASE-ER SFP+ module, and 10GBASE-ZR SFP+ module. This article will introduce one of them, 10GBASE-LR SFP+ module.
10GBASE-LR SFP+ transceiver is designed for single-mode fiber and operates at a nominal wavelength of 1310nm. The 10GBASE-LR transmitter is implemented with a distributed feedback laser (DFB). DFB lasers are more expensive than VCSELs but their high power and longer wavelength allow efficient coupling into the small core of single-mode fiber over greater distances. Compared with 10GBASE-SR, the maximum range of 10GBASE-LR is 10 km.
10GBASE-LR SFP+ transceiver is a hot-swappable SFP+ module that plugs into SFP+ slots on switches. You can connect a 10GBASE-LR SFP+ transceiver while the system is powered on without causing any problems. This permits modules to be added or removed without interrupting the network. The SFP+ form factor is smaller than other form factors such as Xenpak, X2, and 10G XFP, ensuring lower costs, lower power disruption, and higher port density. It provides the necessary signal amplification for data to be transmitted to the network cable from the port, and vice versa, for the port to receive data from the network cable. 10GBASE-LR SFP+ transceiver supports 10G Ethernet, which results in very fast data transmissions of up to 10 Gbit/s. This is 10 times faster than Gigabit Ethernet and enables the switch to handle faster and higher data transmissions, making it very suitable for business needs.
Two Types of 10GBASE-LR SFP+
SFP-10G-LR-S 10GBASE-LR SFP+: The Cisco SFP-10G-LR-S compatible 10GBASE-LR SFP+ transceiver, as shown in the following picture, supports a link length of 10 kilometers on standard single-mode fiber (SMF) (G.652). It is implemented with a DFB laser to support longer distances. And it uses a duplex LC connector.
SFPP-10GE-LR 10GBASE-LR SFP+: The Juniper SFPP-10GE-LR compatible 10GBASE-LR SFP+ transceiver, as shown in the following picture, is guaranteed 100% compatible and functional in its intended equipments. This 1310nm DFB 10Gbps SFP+ transceiver is designed to transmit and receive optical data over single mode optical fiber for link length of 10km. Every SFPP-10GE-LR is environmentally tested in its specific port/platform prior to shipping to ensure that they are in perfect physical and working condition.
SFP+ transceiver is widely used to support communication standards including synchronous optical networking (SONET)/synchronous digital hierarchy (SDH), gigabit ethernet and fiber channel. Fiberstore manufactures a complete range of SFP+ transceivers. Fiberstore 10GBASE SFP+ module series transceivers offer a wide variety of 10G Ethernet connectivity options for data centres, enterprise wiring closets, and service provider transport applications. All of our 10GBASE-LR SFP+ transceivers are tested and fully compatible with major brands like Cisco, HP, Juniper, Brocade and Finisar. We offer high performance and low cost 10GBASE-LR SFP+ transceivers to fulfill customers' requirements.
