About the Cisco MGBBX1
The Cisco MGBBX1 is a hot-swappable SFP 1000BASE-BX BiDi optical transceiver for 1 Gbps Ethernet links over single-mode fiber, with an LC simplex interface and reach of up to 20 km. Cisco description: Cisco Small Business 1000BASE-BX single-strand BiDi SFP. 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 Business / Small Business switches.

MGBBX1: frequently asked questions
What is the Cisco MGBBX1?
The MGBBX1 is an SFP 1000BASE-BX BiDi 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 Business / Small Business switches.
What is the maximum distance of the MGBBX1?
Cisco documentation lists the MGBBX1 for 20km.
Which fiber and connector does the MGBBX1 need?
The MGBBX1 uses an LC simplex connector on single-mode fiber (OS2), single strand. Wavelength: Tx 1310 nm / Rx 1490 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 MGBBX1?
Cisco's Transceiver Module Group (TMG) compatibility matrix lists the MGBBX1 for 6 Cisco device families (for example Cisco Business / Small Business switches). 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 the MGBBX1 still available?
Cisco has announced end-of-sale for the MGBBX1. Next Gen Networks sources genuine new and surplus stock on request; tell us the quantity and we confirm availability or quote the current Cisco equivalent.
Is your MGBBX1 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 MGBBX1 price in India and how do I order?
The Cisco MGBBX1 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.
