Network Extension Up To 30 Km

This desktop media converter extends a Fast Ethernet network over single-mode fibre up to 30 km. It bridges one RJ-45 copper port and one duplex SC optical port. The unit is powered by an included 12 V DC AC adapter. It suits installers who need to link buildings or remote cabinets beyond copper reach.

Capacity And Headroom

The converter handles 10/100 Mbps full-duplex traffic over twisted pair and 100Base-FX over fibre. Maximum span is 30 km on single-mode cable at the specified wavelength. Bandwidth tops out at Fast Ethernet rates, so gigabit or multi-gigabit links are not supported.

Single-Mode SC Duplex Interface

The single-mode SC duplex port is the decisive specification; it only mates with matching single-mode patch cords and SFP optics. Multi-mode fibre, LC connectors or bi-directional single-strand links will not work with this unit.

Questions about this item

Will the 10/100 Mbps RJ-45 port link reliably with older 10 Mbps switches I still use?

Yes, the 10/100Base-TX port auto-negotiates down to 10 Mbps half- or full-duplex, so legacy 10 Mbps equipment will connect without configuration.

How can I confirm the SC single-mode link is operating at the full 30 km reach after installation?

Verify the converter's FX Link LED is solid green and check the switch port counters for zero CRC errors; a clean link at 100Base-FX indicates the 30 km budget is being met.

Does the package include the single-mode duplex SC patch cord needed to reach the remote site, or must I order it separately?

The box contains the media converter, a universal 12 V DC power adapter with Type M plug, a grounding screw and an instruction manual; the SC patch cord is not included and must be purchased separately.
