D-Link 1-port Mini-GBIC SFP to 1000BaseSX Industrial Transceiver

The D-Link DIS-S301SX is a mini-GBIC fiber optic transceiver module designed for 1 Gbit/s network links. With a compact, silver metal housing and a lightweight design (approximately 20 g), the module provides a standard SFP form factor that fits compatible D-Link equipment and other devices supporting mini-GBIC/SFP modules. It supports a maximum data transfer rate of 1000 Mbit/s and is intended to enable fiber connections where copper ports are not suitable or where extended link distances are required.

Advantages

The module’s small SFP/mini-GBIC format reduces occupied space in network equipment while providing full gigabit throughput. Its metal housing and standard connector interface ensure mechanical compatibility and straightforward hot-pluggable insertion into supported slots. The lightweight, compact design simplifies handling and installation in dense rack environments.

Suitable for

• Upgrading switch or router ports from copper to fiber at 1 Gbit/s
• Connecting network equipment across short to medium fiber links where SFP is supported
• Replacing or stocking spare SFP/mini-GBIC transceivers for D-Link devices

Key specifications

• Interface type: mini-GBIC (SFP) form factor
• Maximum data transfer rate: 1000 Mbit/s (1 Gbit/s)
• Weight: approximately 0.02 kg
• Product colour: Silver metal housing

How to use

Power off or follow hot-swap procedures for your network device according to the equipment manufacturer’s instructions before inserting the transceiver. Align the mini-GBIC/SFP module with the device slot and gently push until it clicks into place; secure any ejector latch if present. Connect compatible fiber patch cables to the transceiver’s optical ports, observing correct transmit/receive orientation. Confirm link status on the host device and verify network parameters such as speed and duplex through the device interface.

Recommendations

Handle the transceiver by its housing, avoid touching optical interfaces, and keep protective caps on the fiber ports when the module is not connected. Verify compatibility with the target switch or router and use fiber cable types appropriate for the intended link distance and fiber connector type.
