1000BASE-T Gigabit Ethernet over Category 5 copper cabling is an attractive option for network managers for several reasons. It addresses the exploding bandwidth requirements on current networks that are the result of implementation of new applications and the increasing deployment of switching at the edges of the network. Gigabit Ethernet leverages the organization’s existing investment in Ethernet and Fast Ethernet infrastructures, and it provides a simple, cost-effective performance boost while continuing to use the dominant horizontal/floor-cabling medium.

1000BASE-T Key Specifications

1000BASE-T is specified to run over four pairs of Category 5 balanced cabling. The 1000BASE-T standard leverages the existing cable...

The small form-factor pluggable (SFP) is a compact, hot-pluggable transceiver used for telecommunication and data communications. 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 transceivers can support SONET, Gigabit Ethernet, Fibre Channel, and other communications standards. SFP transceivers are upgraded from the traditional version with more flexibility but a smaller size.

Pluggable fiber optic transceivers refer to hot-swappable or hot-pluggable optical transceivers which can be quickly plugged into an interface of fiber optical devices. An optical transceiver can best be described as a device that converts high-speed data from a cable source to an optical signal for communication over optical fiber. Optical transceivers are used to update the communications networks to manage broadband, to update the data center networks to make them manage traffic with higher speeds, and to implement the backbone network for mobile communications.

Pluggable fiber optic transceivers provide connectivity options for Ethernet over twisted pair copper and fiber optic cables with transition speeds from 100 Megabits per...

1000BASE is a term describing various technologies for transmitting Ethernet frames at a rate of a 1,000,000,000 bits per second, as defined by the IEEE 802.3-2008 standard. 1000BASE SFP transceiver is a hot-swappable input/output device that plugs into a Gigabit Ethernet port/slot, linking the port with the fiber optic network. It can be intermixed in combinations of IEEE 802.3z- compliant 1000BASE-SX, 1000BASE-LX/LH (GLC-LH-SM or GLC-LH-SMD), or 1000BASE-ZX interfaces on a port-by-port basis. Here are the most common types of 1000BASE SFP transceiver modules.

1000BASE-LX SFP Transceiver

LX stands for long wavelength. 1000BASE-LX is a physical layer specification for Gigabit Ethernet over fiber optic cabling as defined in 802.3z....
