CHAPTER 1: INTRODUCTION A fiber optic cable is connected to the transceiver through ST fiber optic ports on the FOT-F3. This provides an optical link to connect the device to the network. 1.3.2 Distance and Cable Type The FOT-F3 supports single mode fiber optic cable for sizes such as 8.3/125 m m, 8.7/125 m m, 9/125 m m, and 10/125 m m. You can also use multimode cable such as 62.5/125 m m, but the signal distance will be much shorter. The signal distance is dependent o

OVERVIEW OF THE FOT-F3 The SQE test signal is generated after the FOT-F3 has transmitted a data packet. This signal is generated only between the FOT-F3 and the device; it is not transmitted onto the network. Note: Do not enable the SQE test feature when the FOT-F3 is attached to a repeater or Ethernet Version 1 equipment. Otherwise, network problems (excess collisions) will result. 1.3.3 LANVIEW LEDs The FOT-F3 incorporates Cabletron Systems LANVIEW diagnostic and monitorin

OVERVIEW OF THE FOT-F3 1.3.4 Application The FOT-F3 can be configured into your network in many ways. For example, in Figure 1-3, a fiber optic link segment (4) is attached to a Cabletron Systems Multi Media Access Center (MMAC) (5) with a FOMIM-32/36/38. The MMAC serves as an intelligent repeater hub that links the fiber optic link segment to other network segments, regardless of media type. The link segment is attached to the FOT-F3 (3). An Ethernet device, such as a workstation (1

CHAPTER 1: INTRODUCTION In another example, shown in Figure 1-4, a FOT-F3 (3) is connected to an MMAC (1) by an AUI cable (2) attached to an Intelligent Repeater Module (IRM) in the MMAC. A lengthy fiber optic link segment (4) of up to five kilometers runs from the FOT-F3 (3) to another FOT-F3 (5). The hardware connection is completed via another AUI cable (6) to a Cabletron Systems NBR-220 Ethernet Bridge (7) configured to provide an AUI interface. Through the bridge, the host dev

CHAPTER 2: INSTALLATION REQUIREMENTS • When determining the maximum fiber optic cable length, the fiber optic budget and total network propagation delay should be calculated and taken into consideration before fiber runs are incorporated into any network design. Fiber optic budget is the combination of the optical loss due to the fiber optic cable, in-line splices, and fiber optic connectors. Propagation delay is the amount of time it takes a packet to travel from the sending devic
