Page 9: Installation Requirements
Welcome to Cabletron Systems FOT-F3 Fiber Optic Transceiver User’s Manual . This manual serves as a simple installation and reference guide for the FOT-F3 transceiver. You should have a general working knowledge of Ethernet or IEEE 802.3 type data communications networks and their physical layer components before installing the FOT-F3. -
Page 10: Conventions
AUI interface (the AUI port connects the transceiver to a device or workstation via an AUI cable). The FOT-F3 also has the Cabletron Systems LANVIEW diagnostic system that monitors network activity and can help to quickly diagnose physical layer problems using its LEDs. -

Version 2, and/or IEEE 802.3 equipment through an AUI port. However, the FOT-F3 uses 1300 nm wave-length optical transmitters and receivers and should be used only with Cabletron Systems Ethernet single mode products such as the FOMIM-36, FOMIM-32, and the FOMIM-38. FOT-F3 USER’S MANUAL... -
Page 12: Chapter 1: Introduction
However, Cabletron Systems only supports a distance of 5 kilometers. If using 62.5/125 multimode cable, signal distance is about 2 km. An AUI cable, up to 50 meters long, is used to connect an Ethernet device to the AUI port on the transceiver. -
Page 13: Lanview Leds
The FOT-F3 incorporates Cabletron Systems LANVIEW diagnostic and monitoring system. LANVIEW is a series of LEDs incorporated into all Cabletron Systems products. If a problem arises, troubleshooting of power failures, collisions, cable faults, or many other problems can be diagnosed rapidly using these LEDs. - Page 14 CHAPTER 1: INTRODUCTION PWR (Power) When on, this green LED indicates that the FOT-F3 is receiving power. SQE (Signal Quality Error) Test Function When on, this yellow LED indicates that SQE is enabled. XMT (Transmit) This green LED flashes to indicate that the FOT-F3 is transmitting frames onto the network.
-
Page 15: 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. - Page 16 (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.

Page 19: Chapter 2 Installation Requirements
INSTALLATION REQUIREMENTS Before installing the FOT-F3 Fiber Optic Transceiver, all conditions, guidelines, specifications, and requirements included in this chapter and Appendix A must be met to ensure satisfactory performance from the FOT-F3. Failure to follow these guidelines may result in unsatisfactory network performance. -
Page 20: Aui Cable Requirements
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. -
Page 21: Chapter 3 Installation
This chapter contains instructions for unpacking the FOT-F3 Transceiver, connecting the FOT-F3 to an Ethernet device and the network, surface mounting the transceiver (if necessary), and cable support installation. Verify that all the requirements listed in Chapter 2, Installation Requirements, and Appendix A, Specifications, are met before installing the transceiver. -

Page 25: Connecting The Fiber Optic Cable
Note: It is recommended to label the fiber optic cable to indicate which fiber is Receive and which is Transmit. When you buy fiber optic cable from Cabletron Systems, at one end of the cable, one fiber is labeled 1, and the other fiber is labeled 2. This pattern is repeated at the other end of the cable. - Page 26 CHAPTER 3: INSTALLATION ST connectors attach to ST ports much like BNC connectors attach to BNC ports. See Figure 3-3. The connector is inserted into the port with an alignment key on the connector inserted into the alignment slot on the port. The connector is then turned to lock it down.
- Page 27 ST Connectors Figure 3-3 ST Connectors Check that the LNK LED on the FOT-F3 is on. If the LED is off, perform each of the following steps until the LED is on: Check that the power is on for the device at the other end of the link.
