SFP transceiver for 550 m multimode links

The PLANET MGB-SX is a hot-pluggable SFP module that delivers a 1 Gbps 1000BASE-SX connection over LC duplex multimode fibre up to 550 metres. It complies with the SFP MSA and IEEE 802.3z so it fits any MSA-compliant port without powering down the host equipment. The unit is built for standard commercial operating temperatures.

Suitable for Gigabit uplinks in campus

Network engineers extending links between switches or servers across multimode fibre runs within 550 metres will find this module a direct fit. It is not intended for single-mode distances beyond 550 metres, nor for industrial environments that demand a -40 °C to 75 °C operating range; the MGB-T series addresses that wider temperature envelope.

Tool-less insertion into any SFP MSA slot

Slide the transceiver into an empty SFP port until it clicks, then connect LC duplex patch cords; no software configuration is required on most managed switches. The only common issue is a link that stays down because the Tx and Rx fibres are crossed — swapping the two connectors at one end restores the signal.

Questions about this item

What type of switch port is required to use this SFP module?

The module fits any SFP MSA compliant port on a switch or router, allowing hot-pluggable installation without powering down the host equipment.

Can this 1000BASE-SX transceiver link to older 100 Mbps fiber equipment?

No, it operates at 1 Gbps under the IEEE 802.3z Gigabit Ethernet standard and does not negotiate down to 100 Mbps fiber speeds.

How can I verify the link is operating at the full 550 metre reach?

Check the switch port status for a 1 Gbps link light and confirm the received optical power falls within the multi-mode receiver sensitivity range.
