Basics of the Cisco GLC-T SFP Modules

In the fiber network, high speed connection is always needed to some type of equipment. As most high speed switches provide small form-factor GBIC slots, a variety of SFP transceivers are needed to handle with. The SFP Gigabit interface converter was developed by Cisco as the current standard. The Cisco compatible transceivers like Cisco GLC-T are used to plug into a Gigable Ethernet port or slot to link the port with the network, allowing for excellent data transmission rates between your Cisco equipments.

GLC-T SFP is a hot pluggable module with RJ45 interface, it is commonly used with 1000Base-T application, when a GLC-T transceiver is plugged into a standard SFP slot, the equipment generally auto detects the device and the hardware will work immediately when the media is connected. This 1000Base-T SFP transceiver supports1000 Mbps full duplex data-links with 5-level Pulse Amplitude Modulation (PAM) signals. All four pairs in the cable are used with symbol rate at 250Mbps on each pair. This GLC-T SFP is compliant to IEEE 802.3 and its dimension is 0.6 in x 2.8 in x 0.6 in.

Cisco SFP or Cisco compatible SPT is extremely preferred when shopping GBIC modules to make sure they are completely compatible with Cisco equipment. Many honest fiber optic manufacturers like Ingellen Technology Co. provide ranges of Cisco compatible SFP transceivers, The Cisco GLC-T SFPs are guaranteed to be 100% compatible with Cisco equipment and stable performance. The Cisco compatible GLC-T SFPs are widely used for the 1.25 Gigabit Ethernet over Cat 5 cable application and share the common features as below:

Up to 1.25Gb/s bi-directional data links
