Cisco (Linksys) compatible MGBBX1 Description
EdgeOptic's MGBBX1 compatible is a Cisco-coded version of the EdgeOptic BiDi-1.25G-SFP-21-AD multi-vendor Gigabit Ethernet BiDi SFP transceiver. MGBBX1 is the Cisco Small Business (formerly Linksys) ordering code in the MGE SFP family, identifying as an upstream 1000BASE-BX-U module built around a single LC/UPC connector on one strand of single-mode fiber. The module is programmed with Cisco-compatible EEPROM coding.
The optical path pairs a 1310 nm transmit wavelength with a 1490 nm receive wavelength, each inside a 40 nm passband. Launch power from the FP laser spans −9 to 3 dBm, and the PIN photodiode receiver holds −22 dBm sensitivity with −3 dBm overload. Chromatic dispersion is bounded at 140 to 160 ps/nm. Supported data rate runs 1.063 to 1.25 Gbps, covering Gigabit Ethernet applications. Reach is 20 km with a 15 dB average link budget on single-mode fiber, and digital diagnostic monitoring follows SFF-8472. Power draw runs on a single 3.3V supply across a standard 0 to 70°C operating range.
Cisco documents the MGE SFP family, which includes MGBBX1, for its 110 Series Unmanaged Switches and 220 Series Smart Switches. Certifications carried on this module include CE, RoHS, Class 1 FDA and IEC 60825-1 laser safety, and the INF-8074i SFP MSA form factor specification.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms, MGBBX1 ships with a lifetime warranty. For project-quantity pricing or an alternative vendor coding, contact our sales team.
Frequently Asked Questions
Which module do I pair with the Cisco MGBBX1?
MGBBX1 operates as the upstream half of a 1000BASE-BX pair. Cisco's Small Business Optical Module Quick-Start Guide documents it as upstream-only, so it must terminate against a downstream BX-D module on the same strand of fiber. EdgeOptic's Side-B compatible, transmitting at 1490 nm and receiving at 1310 nm, is the natural counterpart. Verify the exact downstream part number against the target switch model before ordering.
Is the Cisco MGBBX1 supported on Cisco Small Business switches?
Cisco's MGE SFP datasheet lists MGBBX1 for the 110 Series Unmanaged Switches and 220 Series Smart Switches. For any other Cisco Small Business switch model, check that model's own transceiver compatibility list before ordering.
What is the difference between the MGBBX1 and the Cisco GLC-BX-U?
GLC-BX-U is Cisco's enterprise ordering code for a 1000BASE-BX-U module. MGBBX1 is the Cisco Small Business (formerly Linksys) SKU covering the same upstream BiDi function. EdgeOptic carries both as separate compatible product pages, so match the ordering code to the platform family you are deploying.
