Page 8: Functional Description
Functional description Router TP/FT interface – optical fibre The LRW-112 (LRW-112PP) is a fibre optic router that converts between L ® orks TP/FT, and fibre optical link. Router – optical fibre links The LRW-112 routes LON packets between a TP/FT-10 channel and a fibre optic channel. The communication channels consist of a fibre optic interface and a TP/FT-10 interface. The fibre optic interface is equipped with either one (PP-version) or two sets of fibre optic ports, each with its separate transmitter and receiver, and the TP/FT-10 channel orks ® consists of one L FTT-10A transceiver. Single or multimode LC fibre connectors The LRW-112 (LRW-112PP) uses Small Form Factor Pluggable (SFP) transceivers that are in compliance with Multi-Sourcing Agreement (MSA). A wide range of different fibre transceivers and connectors can be used. 6650-2260... - Page 9 Point-to-point communication (LRW-112PP) via fibre optic network With only two network segments, the most cost effective solution is to use two point- to-point LRW-112PP units to create a single fibre optic connection. The point-to-point connection provides a totally transparent fibre link which means that all data received on one units TP/FT port will be forwarded unchanged to the other port, as illustrated in the figure.

This involves recovery from bus/multi drop network to Redundant ring A/B when ring is up and running and recovery from Ring B to Redundant ring A when the ring is up and running. The time to recover from the failure status depends on total length of fibre ring. This is typically 10–20 ms. During that time the transferred data frames should be seen as corrupted or missed. 6650-2260...
- Page 12 Bus or multidrop communications via fibre optic network CH 2 CH 1 CH 2 CH 1 CH 2 CH 1 CH 2 CH 1 Network Network Network Network The data is transferred via the fibre optic network to the serial ports of all units. If LRW-112 is connected to two optical fibre links (mid unit) converted data will be trans- mitted in both directions, via both CH 1 and CH 2. With only one optical fibre link (end unit) converted data will be transmitted in one direction, via CH 1 only. Data received from one LRW-112 optical fibre port will be repeated through the other optical fibre port and it will also convert the frame to serial data. Optical fibre link functionality and status indication At power on, all LED's will be active during an initiation sequence followed by an auto- matic initiation of the optical fibre links. The alarm will be set until the fibre optical links are in operation and ready to transfer serial data. Data can be transferred over a fibre optical link as long as the link is in operation, indi- cated by active CH1 respective CH2. When any of the fibre optical links is out of operation and this is a faulty state, will it be indi- cated by a local alarm and set the alarm output. It will also send a remote alarm via the other link, if possible. When the link returns to operations mode, the alarm will reset automatically. Redundant power supply, galvanic isolated (2 kVAC) to other ports.

Page 13: Network Installation
Network installation The LRW-112 is installed in the network as any standard LON router. The FO-10 standard channel may be used when creating a channel object. Note: LRW-112 and LRW-102 cannot be used in the same fibre optic network. It is pos- sible to connect LRW-112 and LRW-102 via the LON interface. Status interface This interface enables supervision of fibre optic link state.<8 ohm means that status is OK. The fault state will be set if: … Local or remote fibre link errors exist. … The unit is out of service, e.g. no power supply. LON Channel delay On the fibre channel the devices are attached in a daisy-chain fashion. The signal path is through each device, that is the packet passes through each device on its way. The signal is regenerated each time it passes through a device, thus very long distances network could be built.: The time of propagation depends on the distance and the number of devices to pass through. The propagation delay affects the channel communication parameters. By default the LRW-112 has been programmed with communication parameters suitable for a relative small to medium fibre network that follows the below equation: Fibre distance (m) / 200 + Number of units < 72 For example the above equation would allow four LRW-112 units to use maximum fibre optic cable length of 13.6 km (8.5 mi). For larger networks the LRW-112 can be programmed with communication parameters compensating for longer propagation delays. With parameters for large network the following equation can be used. Fibre distance (m) / 200 + Number of units < 576 For example, the above equation would allow eight LRW-112 units to use maximum fibre optic cable length of 13.6 km (8.5 mi). Observe however that the maximum allowed fibre length between two LRW-112 units is 20 km (12.4 mi) (using singlemode cable) depend- ing on the performance of the fibre optic transmitter and receiver. See page 15 for power budget tables. ® It is recommended to use a LON protocoll analyser to verify network perfomance dur- ing high peak channel access. The above discussion considers the limitation in maximum distace due to protocoll parameters involving media access and network idle detection. As with all fibre optic ... -

The allowed link length is calculated from the Optical Power Budget (OPB), (the available optical power for a fibre-optic link), and the attenuation of the fibre, comprising losses due to in-line con- nectors, splices, optical switches and a margin for link aging (typical 1.5 dB for 1300 nm). The worst-case Optical Power Budget (OPB) in dB for a fibre-optic link is determined by the differ- ence between the minimum transmitter output optical power and the lowest receiver sensitivity.
