Chapter 2: Overview 2. Overview 2.1 Introduction The Pure Networking Fast Ethernet Media Converters connect a 10/100BASE-TX network segment and a 100BASE-FX network segment. Use these units to join a 10/100BASE-TX segment to a 100BASE-FX segment on your network, or use them in pairs to extend the 328-foot (100-m) distance limitation of copper based Ethernet. The converters also feature LFP (Link Fault Passthrough, as described in Section 5.3).
Chapter 2: Overview 2.4 Connectors and Network Cables Supported The connectors and network cables supported by the converter are listed as follows. • Connectors: RJ-45, SC. • Network cables: CAT5 twisted-pair (TP), 1310-nm 62.5/125-µm, 50/125-µm single-mode/multimode fiber. Table 2-1. Connectors and network cable supported.

Chapter 3: Configuration 3. Configuration To expand a Fast Ethernet network, you can use the converter as described in the following examples: 1. Place two converters back to back between the end devices as shown in Figure 3-1. Device A Twistedpair cable Twistedpair cable Device B 10/100BASE-TX interface LHC201A or LHC202A 100BASE-FX interface LHC201A or LHC202A Single-mode or multimode fiber optic cable Figure 3-1. Application using two media converters.
Chapter 3: Configuration 2. Place one converter directly between a 10/100BASE-TX network segment and a 100BASE-FX network segment as shown in Figure 3-2. Device A 10/100BASE-TX interface Device B 100BASE-FX interface Figure 3-2. Application using one LHC201A or one LHC202A. Page 14 724-746-5500 | blackbox.
Chapter 4: Installation 4. Installation 4.1 Typical Installation 1. The SC fiber connector of an LHC201A transmits/receives data by 1310-nm short-wave laser on multimode fiber. 2. The SC fiber connector of an LHC202A transmits/receives data by 1310-nm short-wave laser on single-mode fiber. Figure 4-1 shows a typical installation. Device A Twistedpair cable Twistedpair cable Device B LHC201A or LHC202A LHC201A or LHC202A Multimode or single-mode fiber optic cable Figure 4-1.
Chapter 4: Installation 2. Connect two converters or a converter and a 100BASE-FX device. • Use an SC fiber cable to connect the two converters’ SC connector or the SC connecter of a converter and a 100BASE-FX device. 3. Turn on the power. Page 16 724-746-5500 | blackbox.
Chapter 5: Operation 5. Operation 5.1 LEDs on the Media Converters The converters have real-time LED indicators that can provide real-time status reports. Just look at the LEDs to determine the link status. Figure 5-1 shows the LEDs and Table 5-1 describes their functions. Figure 5-1. LEDs. 724-746-5500 | blackbox.
Chapter 5: Operation Table 5-1. LED functions. Name PWR Status Description ON Power to the unit is ON. OFF Power to the unit is OFF. ON The Link Fault Passthrough (LFP) function is enabled. OFF The Link Fault Passthrough (LFP) function is disabled. ON There is a valid link. Flashing The converter is receiving or transmitting data from the fiberoptic connector. LFP FX Link/Act OFF There is no valid link. ON The TP port is connected to 100BASE-TX.
Chapter 5: Operation 5.2 Switch The converters have a 4-position DIP switch. Figure 5-2 shows the DIP switch and Table 5-2 describes its functions. Figure 5-2. DIP switch. 724-746-5500 | blackbox.
Chapter 5: Operation Table 5-2. DIP switch functions. Switch Position Name Position Description TP-AUTO UP The TP port operates in autonegotiation mode. TP-DIS DOWN The TP port operates in FORCE mode. TP-100M UP The TP port operates in 100BASE-TX mode. TP-10M DOWN The TP port operates in 10BASE-T mode. TP_FDX UP The TP port operates in full-duplex mode. TP_HDX DOWN The TP port operates in half-duplex mode. LFP_OFF UP The Link Fault Passthrough function is disabled.
Chapter 5: Operation Table 5-3. Common configurations.
Chapter 5: Operation 5.3 Link Fault Pass Through Function In common situations, when one side of the link fails, the other side continues transmitting packets and waits for a response that never arrives from the disconnected side. With the Link Fault Passthrough function enabled (optional with switch LFP), the TP port and FX port of the same converter will tell each other the fault link status so that when one side of the link fails, the other side will force the link to shut down as soon as noticed.
