Product Identity

The 3Com 3C900B-FL-ST Etherlink 10 PCI Fiber network card is a new network interface card that connects to a PCI bus and provides a 10 Mbps fibre link using an ST connector. It is intended for systems that need a legacy fibre connection on a PCI expansion slot.

Who It Suits

This card fits administrators maintaining older infrastructure that relies on 10 Mbps fibre over ST connectors and has an available PCI slot. It is not for builders who need Gigabit or faster Ethernet speeds, nor for systems that only offer PCI Express or USB connectivity.

Deciding Specification

The 10 Mbps fibre interface with ST connector is the single specification that determines whether this card matches the network segment and cabling you are connecting to.

Questions about this item

Will the ST fiber connector need replacement after extended use?

The ST connector is a passive mechanical interface with no moving parts or consumable components, so it does not require scheduled replacement under normal operation.

What limits throughput on this 10 Mbps PCI card during sustained transfers?

The 10 Mbps Ethernet PHY and the shared PCI bus bandwidth cap the maximum sustained data rate, which is reached well before the host CPU or memory become a bottleneck.

Does the 3C900B-FL-ST generate noticeable heat or fan noise when running continuously?

The card has no active cooling and draws very little power, so it runs silently and adds only minimal heat inside the chassis during all‑day operation.
