  • Page 9: Introduction

    Introduction The DECrepeater 90FS (also referred to in this manual as the module) is an Ethernet repeater that provides two external 10BaseFL fiber-optic ports and one external AUI port. In this manual, the term 10BaseFL refers to the International Standards Organization (ISO) 8802-3/ANSI/IEEE 802.3 fiber-optic local area networks (LAN) standards.

    A non-responder port provides only partial fault detection because it does not signal the master if a failure occurs in its receive link. NOTE: The DECrepeater 90FS and the DECrepeater 900FP are the only DECrepeaters that can be configured as redundant port repeaters.

  • Page 65: Redundant Fiber-Optic Link Operation

    The active link always remains enabled (active) until a failure is detected on that link. Redundant Fiber-Optic Link Operation When you initially configure the DECrepeater 90FS for redundant operation, the primary port is the active port and the secondary port is the standby port. In operation, the active port communicates with its remote responder port until the master detects a link failure or until the port is internally partitioned.

  • Page 67: Complex Redundant Link Configuration

    Redundant Fiber-Optic Link Configuration (Cont.) Complex Redundant Link Configuration The DECrepeater 90FS also supports a more complex redundant link topology. In general, the redundant link consists of a pair of master ports on one module, each connected to enabled remote ports. The remote ports must reside on the same LAN (or extended LAN), but can be on separate modules as shown in the following illustration.

  • Page 68: Partial Fault Detection

    – Internally detected MAU failure When the DECrepeater 90FS fiber-optic ports are connected to a non-responder repeater, such as the DECrepeater 90FL, 90FA (as shown in the following illustration), or any IEEE 802.3 10BaseFL repeater port, partial fault detection is available.

  • Page 69: Full Fault Detection

    Redundant Fiber-Optic Link Configuration (Cont.) Full Fault Detection The DECrepeater 90FS supports full fault detection. This feature enables the master module to react to failures at either end of the receive or transmit media. If a failure occurs in the responder’s receive port, the responder signals its partner master port.

    DECrepeater 90FS. Note the labeling on the fiber-optic cable that is being installed with the DECrepeater 90FS. Cables are tagged according to fiber type (for example, 50/125-, 62.5/125-, 85/125-, or 100/140-micron fiber) and the attenuation of each cable is also characterized and recorded.

  • Page 72: Foirl Compatibility

    –12.0 dBm average for FOIRL and 10BaseFL devices, respectively. When calculating the loss budget for fiber-optic devices, ensure that the higher output from the DECrepeater 90FS, in conjunction with the increased launch power into the two largest fiber sizes (85/125 and 100/140 microns), does not overload the receivers.

    –12.0 –9.8 –6.5 When the DECrepeater 90FS is connected to short lengths of 85/125-micron or 100/140-micron fiber-optic cable, the connection might require additional attenuation to prevent exceeding the –9.0 dBm peak (–12 dBm average) received power level. To make that determination, do the following: 1.
