Different Versions of GLC-SX-MMD Compared

Below are a few versions discussed of this Module

GLC-SX-MMD vs GLC-SX-SMD

GLC-SX-MMD	GLC-SX-SMD
They are designed for the multi-mode fiber	This type is compatible with both Multi mode fiber and single mode fiber
Supports distances up to 550 meters on OM2 MMF	Supports up to 10 kilometers on SMF and 550 meters MMF
The wavelength can be operated up to 850 nm	Its wavelength can be supported up to 1320 nm, and that’s why it’s quite suitable for longer distance data transfer
It is best for short range buildings and enterprises like data center and offices	Can convey its range to the longer distance of distant buildings and data campuses.

GLC-SX-MMD vs GLC-SX-MM

GLC-SX-MM	GLC-SX-MMD
The GLC-SX-MMD does not support Digital Optical Monitoring (DOM). It lacks the real time monitoring of optical parameters.	GLC-SX-MMD supports DOM. It allows the technologists to operate the module’s operational status in real-time.
The GLC-SX-MM provides reliable Gigabit Ethernet connectivity over Ethernet.	Mostly used in critical Network environments where monitoring and uptime are crucial for the Network.
This Module type is less expensive as compared to the recent one.	It is likely to be more expensive due to the additional features in the module like DOM and temperature range.
It operates in the temperature range up to 70 degrees where the temperature is commercial and can be controlled amongst the data centers and enterprises.	It operates in the temperature which range from -5 to 85 degrees and it’s installed in buildings and industries where the conditions are likely to be less controlled.

GLC-SX-MMD vs GLC-SX-MMD=

GLC-SX-MMD	GLC-SX-MMD=
This is the model’s name of Cisco transceiver usually used Gigabit over Ethernet by multimode fiber	This is exactly the same transceiver as the Cisco sfp GLC-SX-MMD with the addition of the ‘=’
When it is purchased as the larger part of the system. It is given by the warranty of the system.	Since it’s the complete system it came with its own warranty from the larger system of the warranty but it’s the same in terms of its working.
It is purchased with the new equipment or if wanted to upgrade the network.	GLC-SX-MMD= is usually purchased for the replacement or as a spare for other equipment.

GLC-SX-MMD vs GLC-SX-MMD++

GLC-SX-MMD	GLC-SX-MMD++
It is the standard version of the 1000BASE-SX SFP transceiver	It is the other increased version of the GLC-SX-MMD with enhanced features over the real one
It is likely to take more power as compared to the other module types	It is power efficient and likely to take less power than the previous one.
It provides reliable performance to the more distance u to 550 meters distance with multi-mode fiber	It has better performance while performing complex tasks
