Planet MGB-SX SFP-Port 1000BASE-SX mini-GBIC module - 550m

The PLANET MGB-SX is a 1 Gbps 1000BASE-SX mini-GBIC transceiver with a stated reach of 550 m, suited to network deployments that need a short-range SFP optical link.

Recommended For

• Network technicians linking two PLANET switches with SFP slots over existing multimode fiber for a 1 Gbps connection within the module’s 550 m reach.
• IT teams connecting nearby network closets or buildings over multimode fiber when the link needs Gigabit Ethernet and does not exceed 550 m.
• Technicians adding or replacing an optical link in a compatible SFP port who want a hot-pluggable module that can be installed without interrupting host equipment operation.
• Administrators using PLANET media converters or third-party equipment that supports compatible SFP transceivers and needs a 1000BASE-SX multimode-fiber connection.

Real-World Use Scenarios

• Link two compatible PLANET switches in separate network closets over multimode fiber; when the fiber path and optics at both ends are compatible, it provides a 1-Gbps link over distances up to the module’s rated 550 m.
• Add a fiber connection between a PLANET switch and a compatible PLANET media converter; the converter can bridge the fiber segment to an Ethernet-cabled device or network, subject to the converter’s supported SFP type.
• Extend a wired LAN connection between nearby buildings or distant areas of a site using an existing multimode-fiber route; within the supported reach, the link can carry Gigabit Ethernet without relying on a long copper run.
• Upgrade a compatible switch’s SFP uplink from copper networking to fiber; the module supplies a 1000BASE-SX optical connection, provided the switch supports it and the fiber and far-end optic match.
• Install or replace the transceiver in a compatible PLANET switch or media converter without powering down the host; the fiber link itself will be interrupted while the module is being changed.
