Copper-to-fibre conversion

This media converter bridges a 10/100/1000T RJ-45 copper port to a 1000LX/LC single-mode fibre port. It operates at a 1310nm wavelength and extends the link up to 20 km. The unit is TAA compliant and built for commercial network infrastructure.

Network extension scenarios

It suits administrators who need to push a gigabit connection beyond the 100 m copper limit using single-mode fibre. It also fits environments requiring IEEE 802.1Q VLAN tag transparency. Buyers who need multi-mode fibre, SFP flexibility, or 100 Mbps-only fibre ports should look at other models.

Maximum reach decides fit

The 20 km single-mode distance is the specification that determines whether this converter matches the planned link length. Shorter campus runs or longer metro spans will require a different wavelength or power budget.

FeatureExtend Networks
The MMC Series are available in 100Mbps or 1000Mbps models. Depending on the model chosen, the fiber-optic port has options for fixed SC, ST, LC or SFP connectors capable of multi-mode or single-mode fiber connectivity. The twisted-pair copper port has an RJ-45 connector supporting either 100Mbps or 1000Mbps, with a maximum operating distance of 100 meters (328 feet).
VLAN Support
Many new backbone switch products now support the industry-standard IEEE 802.1Q specification for Virtual LANs (VLANs) that send extra-long data packets on the network. The MMC Series are fu

Questions about this item

Should I pick the 100Mbps or 1000Mbps model for my link?

Choose the 1000Mbps model when you need full gigabit throughput over the 20 km single-mode run; the 100Mbps model caps at 100 Mbps and uses the same 1310 nm wavelength.

What does the 20 km figure mean once the converter is installed?

It is the maximum reach on single-mode fiber at 1310 nm; actual distance depends on link budget, splice loss and connector cleanliness, so allow margin for patch cords and aging.

How does the RJ-45 to LC interface limit speed in practice?

The copper port negotiates 10, 100 or 1000 Mbps up to 100 m, while the LC fiber port runs at 1000 Mbps; the slower side sets the link speed.
