The company is an award-winning designer, developer and manufacturer of networking, broadband, digital electronics, voice and data communications solutions for the digital home, Small Office/Home Office (SOHO), Small to Medium Business (SMB) and Workgroup to Enterprise environments. D-Link’s products are aimed at the networking and communications market. There is a number of products provided by D-link. Today, we’ll only introduce an essential part of the switches product line – the D-Link SFP transceiver.

D-Link SFP Module Series

D-Link’s highly integrated transceivers offer low jitter performance for extended optical link support without degradation. D-Link’s new line of Gigabit Interface Converters (GBICs) and Small Form-Factor Pluggables (SFPs) transceivers represent an industry leading combination of performance and affordability. D-Link’s new Gigabit transceivers are available in two form-factors: standard (GBIC) or (SFP) /mini-GBIC.


D-Link DEM-211 SFP

D-Link’s DEM-211 100BASE-FX Multimode LC SFP Transceiver provides a high performance solution for serial optical data communication applications. The DEM-211 has a duplex LC connector and provides an IEEE 802.3u compliant link for up to 100Mbps in half duplex mode (200Mbps full-duplex mode) for fibre cable applications. The high performance DEM-211 enables reliable data transfer in short, intermediate, and long distances for building, factory, campus, and metropolitan networking applications. When two switches are connected together using a DEM-211 transceiver on both ends, link speeds of up to 155Mbps can be attained. The DEM-211 allows you to provide 100BASE-FX SFP fibre optic connectivity on Gigabit combo SFP ports for D-Link switches.

D-Link 1000BASE-T SFP

D-Link DGS-712 SFP

D-Link’s DGS-712 1000BASE-T Copper SFP transceiver is based on the SFP Multi Source Agreement. It is compatible with the Gigabit Ethernet and 1000BASE-T standards as specified in IEEE 802.3z and 802.3ab and supports a maximum cable distance coverage up to 300m link lengths. The DGS-712 plugs into any standard SFP interface allowing for 1000Base-T Gigabit transmission over standard Category 5 twisted pair copper.

D-Link 1000BASE-SX SFP

Cisco GLC-LH-SM SFP Transceiver Modules

SFP transceivers(Small form factor pluggable) is prefered to  easier to change and easier for maintenance rather than traditional modules and is expected to perform at data speeds of up to five gigabits per second (5 Gbps), and possibly higher.

SFP interfaces between communication devices like switches, routers and fibre optic cables, and performs conversions between optical and electrical signals. SFP transceivers support communications standards including synchronous optical networking (SONET)/synchronous digital hierarchy (SDH), gigabit ethernet and fibre channel. They also allow the transport of fast Ethernet and gigabit Ethernet LAN packets over time-division-multiplexing-based WANs, as well as the transmission of E1/T1 streams over packet-switched networks.

SFP Transceivers have a wide range of detachable interfaces to multimode/single-mode fibre optics, which allows users to select the appropriate transceiver according to the required optical range for the network. Signal transmitting rate of SFP modules range from 100Mbps up to 4Gbps or more, working distance of these SFP transceiver modules can be from 500 meters to 100 kilo meters, working wavelength of different SFP modules are typically 850nm, 1310nm and 1550nm, there are also CWDM type SFP transceivers available. There are SFP product numbers below:


GLC LH SM is the Cisco 1000Base LX/LH SFP transceiver module, it is one of the most commonly use SFP. SFP units like the GLC-LH-SM in general have different transmitter and receiver types that allow the consumer to select the best option for their specific situation. Its primary function is to interface with a networking cable and increase the connectivity between two network devices such as mother boards, routers and media converters.

There are many options when it comes to finding a GLC-LH-SM. The GLC-LH-SM SFP Transceiver from the reseller is a Cisco brand mini-GBIC but can be used to work with anyone that builds SFP ports such as HP, Finistar, and Juniper among many others. Finding a compatible transceiver can eat up valuable time for IT pros who are upgrading networks and T3 systems provides the best value and support.

Cisco GLC-LH-SM transceiver is a tool utilized to join Cisco machines like wan interfaces or network switches that make use of sfp transceiver module technological expertise. It is characterized by an LC type interface with a higher density as well as a smaller fibre optic connecter. It is suitable for both single and multimode use and has a working distance of 10 kilometers or 550 meters over MMF. It is compliant to IEEE standards in line with Gigabit Ethernet and comes in a variety of styles to ensure users have the exact choice for their needs.

The GLC-LH-SM is a SFP fibre optic transceiver works at a 1300nm wavelength. When utilized as GLC-SX-MM SFP, the unit has a tier-one laser of 1,300nm for medium range fibre applications. In MMF configuration, the maximum distance is 1,800 ft and on SMF the max distance is 10 Km (6.2 miles).
