Media Converter for Gigabit Fibre

The StarTech.com ET91000SM402 converts a 1000 Mbps Gigabit Ethernet link to single-mode SC fibre. It extends the connection up to 40 km or 24.8 miles. The unit operates standalone or mounts in the ETCHS2U rackmount chassis. Installation is quick and simple.

Suits long copper-to-fibre links; not for short runs

Network managers who need to bridge copper and single-mode fibre over distances up to 40 km will use this converter. It supports full or half-duplex operation and includes link-loss forwarding with remote monitor status. Builders needing multi-mode fibre, shorter reach or additional RJ-45 ports should look at other models.

40 km single-mode SC reach decides fit

The decisive specification is the maximum fibre cable length of 40 km over a single SC port. This distance determines whether the converter matches the planned link budget. If the required span exceeds 40 km or uses a different fibre type, another device is required.

Questions about this item

How is the ET91000SM402 installed, and what step is often missed?

Connect the RJ-45 port to your copper network and the SC port to single-mode fiber; the step often missed is enabling link-loss forwarding so the far-end device detects a break immediately.

What maintenance or replacement will the ET91000SM402 need later?

The SC connector and fiber patch cord should be inspected and cleaned periodically; the converter itself has no moving parts or user-replaceable modules.

What limit appears first on the ET91000SM402 under sustained 1000 Mbps traffic?

The 40 km single-mode fiber distance ceiling is reached before any throughput bottleneck on the Gigabit interfaces.
