About the Cisco MFEBX1
The Cisco MFEBX1 is a hot-swappable SFP 100BASE-BX BiDi optical transceiver for 100 Mbps Ethernet links over single-mode fiber, with an LC simplex interface and reach of up to 20 km. Cisco description: Cisco Small Business 100BASE-BX single-strand BiDi SFP (Tx 1310/Rx 1550). 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 Business / Small Business switches.

MFEBX1: frequently asked questions
What is the Cisco MFEBX1?
The MFEBX1 is an SFP 100BASE-BX BiDi module for 100 Mbps Ethernet links. It is used for Fast Ethernet fiber uplinks, legacy and industrial links on Cisco Business / Small Business switches.
What is the maximum distance of the MFEBX1?
Cisco documentation lists the MFEBX1 for 20km.
Which fiber and connector does the MFEBX1 need?
The MFEBX1 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 MFEBX1?
The MFEBX1 is documented for Cisco Business / Small Business switches. Support depends on the exact chassis, line card and software release; send us your device model and release and we confirm it against Cisco's documentation before dispatch.
Is the MFEBX1 still available?
The MFEBX1 appears in Cisco documents but not in a current Cisco ordering table, so it is supplied from stock on request. Tell us the quantity and we confirm availability or suggest the current equivalent.
Is your MFEBX1 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 MFEBX1 price in India and how do I order?
The Cisco MFEBX1 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.
