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.
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 GLC-LH-SMD and GLC-LH-SM?
Digital optical monitoring is the main difference, but there are still some other differences between Cisco GLC-LH-SM and Cisco GLC-LH-SMD. Cisco GLC-LH-SM can bear the operating temperature range from 0 to 70°C (32 to 158°F), while Cisco GLC-LH-SMD can bear the range from -5°C to 85°C (23 to 185°F).
What is the difference between GLC SX MMD and GLC SX MMD?
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.
Will single mode work over multimode?
A: Generally speaking, the answer is “no”. Large optical loss will occur if a multimode transceiver is connected with single mode fiber. However, the opposite will work. For example, 1000BASE-LX single mode SFP can work on multimode fiber cable by using mode conditioning fiber cable.
What is SX in 1000BASE-SX?
What is 1000Base-SX? 1000Base-SX is a type of standard for implementing Gigabit Ethernet networks. 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.
What is the difference between GLC SX MM and GLC SX MMD?
What speed is GLC LH SMD?
1.25Gbps
Introduction to Cisco GLC-LH-SMD The Cisco GLC-LH-SMD module is designed for single-mode fiber and operates at a nominal wavelength of 1310 nm. The transmitter section uses a DFB laser. It operates data rate up to 1.25Gbps and up to 10 km over single-mode fiber. GLC-LH-SMD interfaces duplex LC connector interface.
