Extenders

Extenders

Extenders carry a signal further than its native medium allows, by converting it to fiber for the long leg and converting it back at the far end. This category presents three extender families — serial to fiber with 35 sitemap locations, Ethernet over coaxial with 34, and DVI / HDMI with 27 — with no representative model page evidenced in the sampled material, so the category page below describes each family in general terms.

Serial to fiber extenders

Serial to fiber extenders carry serial data over fiber, for industrial control, telemetry, and legacy equipment where serial ports remain in service but the distance exceeds what copper serial cables can carry. They suit factories, utilities, and transport systems, where a serial device must reach a distant controller, and where fiber's immunity to electrical interference suits an electrically noisy environment. A buyer who needs serial extension should ask for the serial standard, the distance, and the fiber type in the inquiry, naming the exact equipment.

Ethernet over coaxial extenders

Ethernet over coaxial extenders carry Ethernet over existing coaxial cable, for installations where coaxial cable is already in place — older buildings, hotels, hospitals — and where replacing it with Ethernet cable would cost more than the installation is worth. They suit retrofits, where the cable exists but the network must be modern, and where the coaxial run's length suits the extender's design. A buyer who needs coaxial extension should ask for the cable type, the distance, and the rate in the inquiry, naming the exact installation.

DVI / HDMI extenders

DVI and HDMI extenders carry display signals over fiber, for professional audio-visual installations where a display sits far from its source, and where a copper display cable would lose signal or pick up interference over that distance. They suit conference rooms, control rooms, and digital signage, where the display must show a source from another room or another floor. A buyer who needs display extension should ask for the display standard, the distance, and the fiber type in the inquiry, naming the exact equipment.

What to confirm before ordering

Name the extender family, the signal type, the distance, the equipment at both ends, the quantity you have in mind, and the market you sell into. Ask for the model, the specification for the exact model, the minimum order quantity, the lead time with its meaning, the warranty terms, the payment and shipping terms, and the certificates that apply to your market, by name, with documents attached. No model page for these families is published, so the inquiry is the route to a model.

Before payment, confirm the minimum order quantity, lead time, payment, shipping and warranty terms for your order. Certificates are available upon request.
