What is the difference between LH and LX modules?

The 1000BASE-LX, 1000BASE-LH and 1000BASE-LX/LH all refer to Gigabit Ethernet transmission. Among them, the 1000BASE-LX is a standard specified in IEEE 802.3 Clause 38 which uses a long wavelength laser, while the 1000BASE-LH and 1000BASE-LX/LH are just terms widely used by many vendors. Long Haul (LH) denotes longer distances while Long Wavelength (LX) denotes less energy which is obviously shorter distance. The 1000BASE-LX SFP modules compatible with the IEEE 802.3z 1000BASE-LX standard can achieve a distance up to 10km over single mode fiber. Unlike 1000BASE-LX SFP modules, 1000BASE-LH SFP modules operate at a distance up to 70km over single mode fiber.

Can 1000BASE-LX be compatible with 100BASE-LX?

1000BASE-LX and 100BASE-LX are very different standards. 1000BASE-LX SFP (GLC-LH-SMD) and 100BASE-LX SFP (GLC-FE-100LX) are two module types, one for GE and one for FE slots. The GLC-LH-SMD does not operate at 100Mbps. You will need to use a 100Mb module to connect to another device at 100Mb. Check optical transceiver compatibility with your equipment by reviewing the Cisco Fast Ethernet SFP module compatibility document and choose the one it says is compatible.

Does GLC-LH-SMD work with GLC-LH-SM?

Yes. Both the GLC-LH-SM and GLC-LH-SMD transceivers support the IEEE 802.3 1000BASE-LX/LH standard and so are compatible with each other. The difference between the two is that the GLC-LH-SMD transceiver has additional support for Digital Optical Monitoring capability.

Can the GLC-LH-SMD replace the SFP-GIG-LX?

The optical modules of the same rate and the same type are theoretically compatible. But only through the specific practice test can we know whether it can be placed. Using the optical modules of the same brand with the switch is recommended.
