What is the difference between GLC SX MMD and GLC-SX-MM?
GLC-SX-MM is a legacy model, it doesn’t feature DOM function and is EOL, it comes with the lowest price compared with the others. GLC-SX-MMD is the replacement of GLC-SX-MM which features an enhanced DOM interface, but with a more expensive price.
What is a GLC-SX-MM?
Cisco GLC-SX-MM compatible SFP transceiver supports up to 550m link lengths over multi-mode fiber (MMF) using a wavelength of 850nm via an LC connector.Each SFP transceiver module is individually tested to be used on a series of Cisco switches, routers, servers, network interface card (NICs) etc.
What is GBIC Cisco?
The industry-standard Cisco Gigabit Interface Converter (GBIC) is a hot-swappable input/output device that plugs into a Gigabit Ethernet port or slot, linking the port with the network.
What does SX mean in fiber?
short
The SX in 1000BaseSX stands for short, and it indicates that this version of Gigabit Ethernet is intended for use with short-wavelength transmissions over short cable runs of fiber-optic cabling.
Is GLC-SX-MMD single mode or multimode?
Standard. GLC-SX-MMD, compatible with the IEEE 802.3z 1000BASE-SX standard,operates on legacy 50 μm multimode fiber links up to 550 m and on 62.5 μm Fiber Distributed Data Interface (FDDI)-grade multimode fibers up to 220 m.
What is the difference between SX and LX fiber?
1000BASE-LX single-mode SFP module will work with single-mode fiber in order to perform both transmission and reception of data. Whereas 1000BASE-SX multimode SFP transceiver will work with multimode fiber, which has a thicker core and allows higher speed at shorter distance.
What does GLC SX MMD stand for?
Cisco 1000BASE-SX short wavelength SFP module
GLC-SX-MM typically stands for Cisco 1000BASE-SX short wavelength SFP module. It is also a part number of compatible 1000BASE-SX SFP transceiver with the same function and performance supplied by many other 3rd party vendors.
What is 1000BASE-SX?
1000BASE-SX is a fiber optic Gigabit Ethernet standard for operation over multi-mode fiber using a 770 to 860 nanometer, near infrared (NIR) light wavelength. The standard specifies a distance capability between 220 meters and 550 meters.
What is the difference between a GBIC and an SFP?
They are used to convert optical and electrical signals. GBIC stands for Gigabit Interface Converter and SFP stands for Small Form-factor Pluggable. Although relative models of each technology are equal in performance, SFP’s are generally considered as an upgraded version of a GBIC module, because they are smaller.
What is GLC in Cisco?
GLC-LH-SM is the Cisco 1000Base LX/LH SFP transceiver module, which is one of the most commonly used SFP module. It is hot-swappable and designed to plug directly into SFP/GBIC interface port or slot in your router and switch for Ethernet & Fibre Channel network applications.
What does GLC-TE mean?
The GLC-T is referring to 1000BASE-T Small Form-Factor Pluggable (SFP) Gigabit Interface Converter. It is a hot-swappable I / O device that plugs into Gigabit Ethernet ports or slots to connect ports to the network.
