Cisco (Linksys) compatible MGBSX1 Description
EdgeOptic's MGBSX1 compatible is a Cisco-coded version of the EdgeOptic 1.25G-SFP-550D multi-vendor 1000BASE-SX transceiver, a drop-in replacement for the Cisco MGBSX1 Gigabit SX Mini-GBIC SFP. It runs Gigabit Ethernet at 1.25 Gbps (IEEE 802.3z) and 1G Fibre Channel SW at 1.0625 Gbps over duplex multimode fiber, with an 850nm VCSEL transmitter and a PIN photodiode receiver.
The EdgeOptic module carries a minimum guaranteed optical budget of 7.5 dB and reaches up to 550m over OM2 multimode fiber (50/125, 500 MHz·km) and 275m over OM1 (62.5/125) per IEEE 802.3z. Cisco's original MGBSX1 datasheet specifies a maximum reach of 500m. It uses a duplex LC/UPC interface and supports DDM/DOM diagnostics for live monitoring of optical power, bias current, and temperature. The module operates over the commercial 0 to 70°C range, built to the INF-8074i SFP MSA, +3.3V supply, CE/RoHS, Class 1 laser safety.
MGBSX1 is a Cisco Small Business (formerly Linksys) optic. EdgeOptic codes the EEPROM so it is accepted on Cisco Small Business switches, including the SF and SG series. It is not qualified for Cisco Catalyst, Nexus, or other enterprise platforms; for those switches, order the matching enterprise-series SFP instead. Confirm your switch model against Cisco's MGBSX1 documentation before ordering.
Backed by 15+ years of EdgeOptic compatibility engineering across vendor optical platforms. Ships next business day from EU stock with a lifetime warranty. For switch-compatibility questions or a quote, contact our sales team.
Frequently Asked Questions
Is the MGBSX1 compatible with Cisco Catalyst or enterprise switches, or only Cisco Small Business switches?
MGBSX1 is a Cisco Small Business (formerly Linksys) SFP designed for Cisco SF and SG series switches. It is not qualified for Cisco Catalyst, Nexus, or other enterprise platforms; for those switches, order the matching enterprise-series 1000BASE-SX SFP for your platform.
What reach does the MGBSX1 support over multimode fiber?
Cisco's MGBSX1 datasheet specifies a maximum reach of 500m. The EdgeOptic compatible reaches up to 550m over OM2 multimode fiber (50/125, 500 MHz·km) and 275m over OM1, the IEEE 802.3z 1000BASE-SX limits for those fiber grades. Both ends of the link must use the same fiber type, and actual distance depends on connector and splice loss in your plant.
