ATOP SF63 Serial to Fibre Media Converter
Request a price
The ATOP SF63 is a DIN-rail serial-to-fibre media converter that carries RS-232, RS-422 or RS-485 signals over one 100BASE-FX fibre port in a metal housing. Multi-mode versions reach up to 2 km and single-mode versions up to 30 km, with SC or ST connectors. The fibre link isolates the serial line electrically, which suits long runs between buildings and electrically noisy plant areas.
Max. Transmission Distance2 km multi-mode, 30 km single-mode

Description
The ATOP SF63 is an industrial serial-to-fibre media converter that carries RS-232 and RS-422/485 serial signals over optical fibre, extending communications well beyond the limits of copper. It converts between 100BaseFX fibre and serial, using multi-mode SC or ST connectors for distances up to 2 km, or single-mode SC or ST for up to 30 km. Fibre also gives complete electrical isolation and immunity to the electromagnetic interference found around motors, drives and high-voltage plant. The rugged design is intended for harsh industrial environments and complies with FCC and CE standards. Typical UK uses include linking serial devices across large sites, between buildings, or through electrically noisy areas. See our serial to fibre media converters.

Specifications taken from the manufacturer datasheet.
Which version do I need?
This page covers the SF63 series. ATOP's brochure lists four codes: SF63-TB-DB-1Fm-SC-2 (multi-mode, SC, 2 km), SF63-TB-DB-1Fs-SC-30 (single-mode, SC, 30 km), SF63-TB-DB-1Fm-ST-2 (multi-mode, ST, 2 km) and SF63-TB-DB-1Fs-ST-30 (single-mode, ST, 30 km). In the code, 1Fm means one multi-mode fibre port, 1Fs one single-mode port, and the final number is the maximum distance in km. Choose the fibre mode to match the cable already installed, or single-mode for runs over 2 km, and the connector to match your patch panel.
Typical applications for the SF63
- Extending RS-485 or RS-422 links between buildings on a large site
- Serial links through electrically noisy areas around motors, drives and high-voltage plant
- Breaking ground loops on long serial runs through fibre isolation
- Connecting remote serial instruments up to 30 km away over single-mode fibre
- Re-using existing multi-mode fibre for a serial link up to 2 km
- DIN-rail cabinet installations needing a metal-housed converter

SF63 — frequently asked questions
How far can the SF63 transmit?
Up to 2 km on multi-mode fibre with the 1Fm codes, and up to 30 km on single-mode fibre with the 1Fs codes.
Which serial standards does it carry?
RS-232, RS-422 and RS-485. ATOP's brochure lists one serial port per converter, on a TB5 terminal block.
Should I choose SC or ST connectors?
Both are offered at each distance: codes ending -SC-2 or -SC-30 use SC connectors, and -ST-2 or -ST-30 use ST. Choose the one that matches your existing fibre terminations or patch panel.
Why use fibre instead of a longer copper RS-485 run?
Fibre gives complete electrical isolation between the ends and is immune to interference from motors, drives and high-voltage plant. It also extends the link to 2 km on multi-mode or 30 km on single-mode.
Does it support redundant power?
Yes. ATOP states that all of its media converters come with redundant power inputs. The SF63 mounts on DIN rail in a metal housing.
Which standards does it comply with?
The product datasheet states compliance with FCC and CE standards.
