About the Cisco S1G-SX-PM-D-I
The Cisco S1G-SX-PM-D-I is a hot-swappable SFP IEEE 1000BASE-SX optical transceiver for 1 Gbps Ethernet links over multimode fiber, with an LC interface and reach of up to 550 m. 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 ASR 900 / ASR 9000, NCS 540 / 560 / 5500 / 5700 and Cisco 8000 routers.

S1G-SX-PM-D-I: frequently asked questions
What is the Cisco S1G-SX-PM-D-I?
The S1G-SX-PM-D-I is an SFP IEEE 1000BASE-SX 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 ASR 900 / ASR 9000, NCS 540 / 560 / 5500 / 5700 and Cisco 8000 routers.
What is the maximum distance of the S1G-SX-PM-D-I?
Cisco documentation lists the S1G-SX-PM-D-I for 550m.
Which fiber and connector does the S1G-SX-PM-D-I need?
The S1G-SX-PM-D-I uses an LC connector on multimode fiber (OM3/OM4). Wavelength: 850 nm. Both ends of the link must use the same optical standard.
Which Cisco devices support the S1G-SX-PM-D-I?
Cisco's Transceiver Module Group (TMG) compatibility matrix lists the S1G-SX-PM-D-I for 5 Cisco device families (for example Cisco ASR 900 / ASR 9000, NCS 540 / 560 / 5500 / 5700 and Cisco 8000 routers). 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 S1G-SX-PM-D-I 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 S1G-SX-PM-D-I price in India and how do I order?
The Cisco S1G-SX-PM-D-I 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.
