Standalone Media Converter Mount

The Perle SMI-110-S2ST40 is a managed media converter mount designed for network administrators extending copper links over single-mode fibre. It bridges 10/100BASE-TX equipment to 100BASE-EX optical segments in campus or metropolitan deployments.

100BASE-EX Single-Mode Interface

The ST connector operates at 1310 nm and supports links up to 40 km or 24.9 miles. Maximum frame size is 2048 bytes, and the RJ-45 copper port auto-negotiates at 10 or 100 Mbps over 100 m or 328 ft. A USA power cord is included for immediate operation.

DIN-Rail or Wall Installation

The compact chassis mounts on standard DIN rail or a flat surface without tools. Common issues arise when fibre polarity is reversed at the ST patch panel or when the copper link partner forces half-duplex, causing collisions on the 100BASE-EX segment. Managed features require browser access to the IP address assigned by DHCP or static configuration.

Questions about this item

Will the ST fibre connector or RJ-45 port on the SMI-110-S2ST40 need periodic cleaning or replacement?

The ST single-mode connector and RJ-45 jack are passive interfaces; they require no scheduled replacement, only occasional inspection and cleaning if signal loss appears.

What is the maximum frame size the converter can handle before dropping packets?

The unit supports a maximum frame size of 2048 bytes; frames larger than this will be discarded.

How much heat does the SMI-110-S2ST40 produce when running continuously?

The converter is passively cooled with no fan; it dissipates low heat suitable for desktop or rack mounting without active airflow.
