1000Base-SX SFP module for data networking

This HPE 453151-B21 transceiver provides a single 1000Base-SX port for Gigabit Ethernet links over multimode fibre. It is built for network administrators who need to add or replace a fibre uplink in a compatible HPE switch or router. The mini-GBIC form factor allows hot-swappable installation without powering down the chassis.

Passive operation with no active cooling

The module draws minimal power directly from the host switch port and has no moving parts, so it adds no audible noise to the rack. Thermal output is negligible in normal operation, leaving the existing chassis airflow unchanged. Its passive design suits dense switch deployments where fanless optics are preferred.

One 1000Base-SX port at 1 Gbps maximum

The only link speed available is 1000 Mbps over multimode fibre, so the module cannot negotiate 10 Gbps or 100 Mbps connections. Buyers who need higher throughput, single-mode reach or copper RJ-45 connectivity must select a different transceiver. Compatibility is limited to equipment that explicitly supports the 453151-B21 part number.

Questions about this item

How do I install the 453151-B21 SFP module and which step is often missed?

Insert the module into a compatible SFP port until it clicks, then connect a duplex LC multimode fibre patch cord; the step often missed is removing the dust caps from both the module and the cable before linking them.

What maintenance or replacement will the 453151-B21 need over time?

The module itself has no moving parts or consumable components; periodic maintenance is limited to inspecting and cleaning the LC fibre connectors if signal loss appears.

What is the first limit that appears on the 453151-B21 during sustained 1000 Mbps traffic?

The single 1000Base-SX port caps throughput at 1000 Mbps, so sustained loads saturate that bandwidth ceiling before any other constraint arises.
