The Simplex 4100-6120 is a left-port, single-mode fiber modem assembly for the Simplex 4120 fire alarm network. Specifically, it links network nodes over single-mode fiber-optic cable. As a result, panels communicate reliably across long distances.
Simplex 4100-6120 Fiber Modem Overview
This assembly serves the left port of a network media connection. In a fiber link, a left port always pairs with a right port. Therefore, you connect the 4100-6120 to a matching right-port modem at the next node.
Single-mode fiber supports longer runs than multi-mode fiber. As a result, this modem suits campus and high-rise network spans. It installs onto the 4100/4120 network interface hardware.
Ordering the Correct Fiber Modem
Fiber modems come in left-port and right-port versions. They also come in single-mode and multi-mode types. First, identify your fiber type and port; then call our team to confirm the right pairing.
