Why Needs Cisco GLC-LH-SM Transceiver

Fiber optic technology has proven itself as an indispensable component for network backbone and other high-demand applications as it generally offers greater bandwidth than traditional copper cable. However, fiber optic cables are made of a specialized glass-like material that costs more to manufacture than traditional copper networking cables. Additionally, the interfaces on either end of […]

1000BASE-SX SFP Transceivers for Gigabit Ethernet

Standardized by the IEEE, Gigabit Ethernet is a term describing various technologies for transmitting Ethernet frames at a rate of a Gigabit per second, which has been considered to be a viable solution for increased bandwidth requirements for growing networks. 1000BASE SFP transceiver is a hot-pluggable input/output device that plugs into a Gigabit Ethernet port/slot, […]

Dig Deeper Into SFP Transceivers

Small form-factor pluggable (SFP) is a prevailing type of optical transceivers in the market widely utilized for Gigabit Ethernet application. As it has the same function with GBIC but with a smaller size, SFP transceiver is also called mini-GBIC. Optical transceivers are typically designed to both transmit and receive electrical optical signals under the Multi-Source […]

The Basics of 1000BASE-SX and 1000BASE-LX SFP

Gigabit Ethernet has been regarded as a huge breakthrough of telecom industry by offering speeds of up to 100Mbps. Gigabit Ethernet is a standard for transmitting Ethernet frames at a rate of a gigabit per second. There are five physical layer standards for Gigabit Ethernet using optical fiber (1000BASE-X), twisted pair cable (1000BASE-T), or shielded […]

What Does DOM Mean for a SFP Transceiver?

If you take a look at the description of a SFP transceiver module, you will see the “DOM support” appeared in the product details. What does it mean? In fact, DOM or Digital Optical Monitoring as the words implies, is used for monitoring some parameters of the transceiver, which can help to identify the location […]
