RGB Spectrum 920 12400 – Single-Mode Fiber Transceiver for XtendPoint

Product Overview

The 920 12400 is a single-mode fiber optic transceiver supplied by RGB Spectrum for XtendPoint KVM-over-IP appliances. Each XtendPoint transmitter and receiver provides an RJ-45 gigabit port and an SFP cage, and RGB Spectrum states that the cage supports either a multi-mode or a single-mode transceiver. This part is the single-mode option, which is the one specified when the KVM link has to travel further than multi-mode fiber or copper will carry it — between buildings on a campus, or from a secure equipment room to a distant operator position. It is a plug-in optic, so no configuration is involved on the appliance.

Product Description

XtendPoint transmitters and receivers connect an operator's keyboard, video, mouse and USB peripherals to a computer that lives somewhere else, and the link between them is an ordinary IP path. On short runs that path is copper. Once the distance exceeds what structured cable supports, or the route crosses between buildings where an electrical connection is undesirable, the fiber option becomes the design. The 920 12400 populates the SFP cage on an XtendPoint appliance so that the KVM link runs over single-mode fiber, which is the fiber type used for the longest reaches in campus and government infrastructure.

Fiber transceivers are ordered in matched pairs — one at each end of the link, or one in each appliance and one in the switch port that serves it — so a single-transmitter, single-receiver link normally needs two of this part. The related multi-mode option is the 920 12399, which is the correct part where the site's existing fiber plant is OM3 or OM4 rather than OS1 or OS2. XtendPoint appliances themselves — the two-signal and four-signal transmitters and receivers — are live RGB Spectrum products and each carries its own SFP cage; a receiver-side deployment can be aggregated with the XP LINK KM aggregator, mounted with the XP RAK 1RU rackmount tray, and driven to the operator's CM 43 curved monitor.

Before ordering, confirm the fiber type already installed on the route, because a single-mode optic will not work over multi-mode fiber and the two are not interchangeable. Confirm the connector type on the existing patch panel, the measured link distance, and the optical budget of the route including every splice and patch. RGB Spectrum publishes no wavelength, reach or optical budget figures for this part number, so those values should be confirmed before the design is committed and the fiber is terminated.

Key Features

• Fits the XtendPoint SFP cage — RGB Spectrum specifies the SFP cage on XtendPoint appliances as supporting a multi-mode or single-mode transceiver, and this is the vendor single-mode option.
• Single-mode fiber for the longest reaches — Single-mode is the fiber type used where a KVM-over-IP link has to cross a campus or connect separate buildings.
• Electrically isolated link — A fiber path between operator position and equipment room removes copper between the two, which suits routes that cross power domains or building boundaries.
• No appliance configuration — The optic plugs into the existing cage and needs no setup on the XtendPoint appliance beyond the network configuration already in place.
• Ordered per port — Quantities are simple to plan: one transceiver in every appliance or switch port that terminates the fiber link.
• Vendor-supplied optic — Sourcing the RGB Spectrum part avoids the compatibility and coding problems that third-party optics can create in a vendor SFP cage.
