About the Cisco GLC-FE-100BX-U
The Cisco GLC-FE-100BX-U is a hot-swappable SFP 100BASE-BX10-U BiDi optical transceiver for 100 Mbps Ethernet links over single-mode fiber, with an LC simplex interface and reach of up to 10 km. Cisco description: 100BASE-BX10-U single-strand BiDi SFP (upstream), COM temp. 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: Fast Ethernet fiber uplinks, legacy and industrial links on Cisco Catalyst, Nexus, ASR / NCS router and UCS platforms.

GLC-FE-100BX-U: frequently asked questions
What is the Cisco GLC-FE-100BX-U?
The GLC-FE-100BX-U is an SFP 100BASE-BX10-U BiDi module for 100 Mbps Ethernet links. It is used for Fast Ethernet fiber uplinks, legacy and industrial links on Cisco Catalyst, Nexus, ASR / NCS router and UCS platforms.
What is the maximum distance of the GLC-FE-100BX-U?
Cisco documentation lists the GLC-FE-100BX-U for 10km.
Which fiber and connector does the GLC-FE-100BX-U need?
The GLC-FE-100BX-U uses an LC simplex connector on single-mode fiber (OS2), single strand. Wavelength: Tx 1310 nm / Rx 1550 nm. BiDi optics use different wavelengths in each direction: pair a D (downstream) module with a U (upstream) module, or use the same BiDi model at both ends where Cisco specifies a symmetric BiDi.
Which Cisco devices support the GLC-FE-100BX-U?
Cisco's Transceiver Module Group (TMG) compatibility matrix lists the GLC-FE-100BX-U for 46 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-FE-100BX-U 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-FE-100BX-U price in India and how do I order?
The Cisco GLC-FE-100BX-U 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.
