More Information

Overview Manuals Optical Budget Fiber Pairing Host Interface Link Diagnosis

Features:

  • Two SC optical ports extend a compatible SCALANCE switch with gigabit fiber links.
  • Each port uses 850 nm multimode transmission over a paired-fiber path.
  • The host switch supplies power and presents module and port status.
A link requires compatible optics at both ends as well as the correct fiber type.

Transmit power and receiver sensitivity define the usable optical budget.

The plug-in slot connects the optical interfaces to the host switching fabric.

The Siemens 6GK5992-2AL00-8AA0 SCALANCE MM992-2 Media Module may remain available for quotation and support beyond End-Of-Life (EOL) by the manufacturer (OEM).

Relating transmitter output to received signal margin

  • Transmit level: The laser launches within the documented power range.
  • Path loss: Fiber attenuation and every connector consume part of the budget.
  • Receiver limit: The far-end signal must remain above the sensitivity threshold.
  • Distance result: The complete loss calculation must fit inside the 750 m multimode limit.

Keeping transmit and receive strands correctly assigned

  • Local TX: One strand carries light from the first device to the remote RX.
  • Local RX: The return strand carries the remote transmitter back to the local receiver.
  • SC ferrules: Clean connectors reduce reflection and insertion loss.
  • Peer optics: The remote module must use compatible rate, wavelength and fiber type.

Connecting the plug-in optics to the switching fabric

  • Module slot: The MM992-2 seats in a supported SCALANCE media-module position.
  • Power path: Operating power enters from the host switch rather than a separate supply.
  • Data path: Each optical port feeds the host switching matrix.
  • Diagnostics: The switch reports the port and module states used during commissioning.

Separating optical faults from host-switch conditions

  • Module recognition: Confirm that the switch detects the installed media module.
  • Port state: Check administrative enable and negotiated gigabit operation.
  • Light path: Inspect polarity, connector cleanliness, patch type and received level.
  • Environmental check: Verify enclosure temperature and the IP20 installation boundary.
Description
Installed in a compatible SCALANCE switch, Siemens 6GK5992-2AL00-8AA0 functions as the MM992-2 plug-in media module that adds two 1000 Mbit/s SC optical interfaces. It converts the switch backplane connection into two multimode fiber paths for network links that cannot use the base unit alone.

Light leaves each port of 6GK5992-2AL00-8AA0 at 850 nm and returns through a separate multimode fiber. The transmitter power, receiver sensitivity, cable attenuation and connector losses together determine whether the optical budget supports the intended distance up to the documented limit.

Both SC connections on 6GK5992-2AL00-8AA0 carry gigabit Ethernet, so the two strands and transmit-receive orientation must remain consistent at each end. Dirty ferrules, crossed fibers or a single-mode patch lead can prevent a link even when the host switch recognizes the media module.

Installed in the assigned SCALANCE slot, 6GK5992-2AL00-8AA0 relies on the host switch for power, configuration and port diagnostics. Its IP20 construction and temperature limits therefore apply together with the enclosure, airflow and operating limits of the complete switch.

FAQS

The following is a list of questions commonly asked by our customers. Please contact us if you have a question about our process that is not answered below.
Why does Siemens 6GK5992-2AL00-8AA0 show no fiber link after installation?
Check Siemens 6GK5992-2AL00-8AA0 host-switch compatibility, module seating, port enable, SC polarity, connector cleanliness, multimode fiber, peer optics, and received power.
What determines the usable distance of 6GK5992-2AL00-8AA0?
The 6GK5992-2AL00-8AA0 transmit range, receiver sensitivity, fiber attenuation, connector losses and remote optics must fit within its 750 m multimode limit.
Can single-mode patch cable be used with Siemens 6GK5992-2AL00-8AA0?
Siemens 6GK5992-2AL00-8AA0 is specified for 850 nm multimode fiber; use the documented multimode cable and compatible peer optics.
Which items should be inspected before replacing 6GK5992-2AL00-8AA0?
Inspect the 6GK5992-2AL00-8AA0 host slot, both SC ferrules, fiber labels, transmit-receive pairing, remote module type, and current port diagnostics.
Does 6GK5992-2AL00-8AA0 require a separate power supply?
No. 6GK5992-2AL00-8AA0 receives power through the supported SCALANCE host slot, while the host switch provides the network configuration and diagnostics.
