GLC-EX-SMD 1000BASE-EX SFP Transceivers

GLC-LH-SMD stands for Gigabit Ethernet SFP, Long-Haul, with a Serial ID (digital diagnostics support). The 'LH' denotes long-haul/long-wavelength operation, while 'SMD' indicates the module includes a digital optical monitoring feature required by newer Cisco platforms.

Both are long-haul Gigabit SFP transceivers, but GLC-LH-SMD includes a Serial ID chip enabling digital diagnostics monitoring (DOM), which is required for compatibility with newer Cisco IOS versions. GLC-LH-SM lacks this feature and may not be recognized by systems requiring the Serial ID.

The GLC-EX-SMD is rated for extended-reach transmission over single-mode fiber, typically supporting distances up to 40 km depending on fiber quality and network conditions, making it suitable for connecting distant data center or campus network locations.

The GLC-EX-SMD is designed to be compatible with a wide range of Cisco switching and routing platforms that support GE SFP modules with LC connectors. Confirm compatibility with your specific Cisco hardware model and IOS version before deployment.

The GLC-EX-SMD uses a standard LC connector, which is common across Gigabit Ethernet SFP transceivers, allowing straightforward integration into existing single-mode fiber optic cabling infrastructure without requiring adapters.

Yes, every GLC-EX-SMD transceiver sold by Terabit Systems is backed by a warranty following a rigorous 5-step quality assurance and testing process, along with a 1-year replacement or full refund guarantee for added peace of mind.
