About the Cisco GLC-EX-SMD
The Cisco GLC-EX-SMD is a hot-swappable SFP 1000BASE-EX optical transceiver for 1 Gbps Ethernet links over single-mode fiber, with an LC interface and reach of up to 40 km. Cisco description: 1000BASE-EX SFP with DOM, EXT temp (5 dB inline attenuator needed back-to-back). Cisco IOS XE, NX-OS, IOS XR and ONS software read the Cisco coding at insertion, so a genuine module avoids 'unsupported transceiver' messages. Typical uses: Gigabit uplinks, campus and inter-building fiber, access and WAN hand-off links on Cisco Catalyst, Nexus, ASR / NCS router and UCS platforms.

GLC-EX-SMD: frequently asked questions
What is the Cisco GLC-EX-SMD?
The GLC-EX-SMD is an SFP 1000BASE-EX module for 1 Gbps Ethernet links. It is used for Gigabit uplinks, campus and inter-building fiber, access and WAN hand-off links on Cisco Catalyst, Nexus, ASR / NCS router and UCS platforms.
What is the maximum distance of the GLC-EX-SMD?
Cisco documentation lists the GLC-EX-SMD for 40km.
Which fiber and connector does the GLC-EX-SMD need?
The GLC-EX-SMD uses an LC connector on single-mode fiber (OS2). Wavelength: 1310 nm. Both ends of the link must use the same optical standard.
Which Cisco devices support the GLC-EX-SMD?
Cisco's Transceiver Module Group (TMG) compatibility matrix lists the GLC-EX-SMD for 109 Cisco device families (for example Cisco Catalyst, Nexus, ASR / NCS router and UCS platforms). Support depends on the exact line card and software release, so send us your device model and release and we check the matrix before dispatch.
Is your GLC-EX-SMD genuine Cisco?
Yes. Next Gen Networks supplies original Cisco parts, not third-party lookalikes or grey-market stock. Every unit is checked before dispatch and we share serial numbers on request so you can verify them in 'show inventory' / the transceiver page. If you want a lower-cost Cisco-coded compatible module for non-critical links, ask us and we quote both options.
What is the GLC-EX-SMD price in India and how do I order?
The Cisco GLC-EX-SMD price in India depends on quantity, delivery city and current stock. Next Gen Networks supplies it with a GST invoice (input tax credit ready) and pan-India dispatch from New Delhi. Send the part number, quantity and delivery city on WhatsApp +91-7827955775 or email Sales@nextgennetworks.in and we reply with a GST quote.
