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.

What is SX in Cisco?

Cisco TelePresence SX Series Quick Set These flexible and highly scalable codec and camera sets can easily turn any flat panel display into a video collaboration system for small-to-medium size meeting rooms and huddle spaces. The SX10 is ideal for small meeting rooms and huddle spaces.

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 SFP and GLC?

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℃).

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 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 SX SFP?

Comparatively, multimode SFP transceivers are identified with “SX”. This MMF SFP optics is specially for short distance data transmission. The common multimode SFP modules work in 850nm wavelength and is only used for short distance transmission reaching 100m and 500m.

How fast is 1000BASE-SX?

Operating speed of 1000Base-SX Gigabit Ethernet is 1 Gbps (1,000,000,000 bits per second). Gigabit Ethernet supports distances between 220 to 550 meters.

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.

Can I use a multimode SFP on single mode fiber?

So technically speaking – it is possible to connect multimode SFP with Single mode fiber – but connection will be unreliable, unpredictable and very short.

What is 1000BASE SX?

What is GLC 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.
