What is the difference between GLC-SX-MMD and GLC-SX-MM?

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.19 Jun 2017

Is GLC-SX-MMD multimode or single mode?

The GLC-SX-MMD 1000BASE-SX SFP is made for Multimode Fiber only. The 1000BASE-SX SFP, 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 SFP Single-mode. SX stands for short wavelength. The “LX” in 1000BASE-LX stands for long wavelength, indicating that this version of Gigabit Ethernet is intended for use with long-wavelength transmissions (1270 1355nm) over long cable runs of fiber optic cabling.7 Dec 2017

What is GLC connector?

The GLC-LH-SM is used for short to medium fiber connections (up to 25 miles using single mode duplex cable). This mini GBIC is carrier-class quality and can be fully trusted for your most demanding LAN/WAN applications, voice projects, or network deployments.

What is a GLC-SX-MM?

GLC-SX-MM typically stands for Cisco 1000BASE-SX short wavelength SFP module. It is a 1000BASE-SX SFP transceiver that allows users to use existing cable runs in distances up to 550m on 50/125, 220M on 62.5/125 and 1km over 50/125 OM3 fiber cables.2 Apr 2019

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.12 Jul 2017

What does SX mean in fiber?

Name Media Mode | Wavelength ---- ------------------------- ----------------- SX Fiber Optic Short Range Multi|850 nm LX Fiber Optic Long Range Single | 1310 nm ZX Fiber Optic Long Range Single | 1550 nm SR Fiber Optic Short Range Multi | 850 nm

What is GLC in SFP?

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.19 Dec 2017

What is GLC module?

Cisco GLC-T SFP Transceiver Basis Cisco industry-stand 1000BASE-T GLC-T SFP module is a hot-swappable input/output copper transceiver which operates on Cat5 wiring of up to 100m link length. Here is the datasheet of Cisco GLC-T SFP copper module.

What is difference between GLC and SFP?

The first big difference between the two SFP modules is SFP-GE-L SFP supports DOM (digital optical monitoring) while GLC-LH-SM module doesn't. The temperature range of Cisco GLC-LH-SM SFP is 32℉to 158℉(0℃ to 70℃), while the extended operating temperature range of SFP-GE-L module is 23℉ to 185℉ (-5℃ to 85℃).14 Oct 2017

What is GLC in Cisco?

Cisco GLC-T SFP is a 1000BASE-T Small Form-Factor Pluggable RJ45 interface converter. It can be inserted into Gigabit Ethernet ports to connect ports to the network. GLC-T SFP transceiver provides 1Gbps data transmission. Besides, it supports the full-duplex Gigabit Ethernet connection for the high-end workstation.16 Oct 2018

What is LX port?

The “LX” in 1000BASE-LX stands for long wavelength, indicating that this version of Gigabit Ethernet is intended for use with long-wavelength transmissions (1270–1355 nm) over long cable runs of fiber optic cabling.13 Jun 2017
