OPTICAL SYSTEMS DESIGN OSD2151 FRONT AND REAR PANELS There is one fixed copper port for 10/100/1000Base-T and one SFP port on the front panel. The SFP device is sold separately giving the user choice to use either one or two fiber communications with various optical power outputs depending on the distance required.
OPTICAL SYSTEMS DESIGN 2 INSTALLATION AND OPERATION INTRODUCTION This section outlines the methods required to install and operate the OSD2151 successfully. It should be studied carefully if damage to the equipment or poor results are to be avoided. This equipment has been fully tested prior to dispatch and is ready for immediate operation. However it is advisable to check for external transportation damage before operation.

OPTICAL SYSTEMS DESIGN 2.2.6 CONTROLS The OSD2151 has a 3-way DIP switch to control a number of functions. Table 4 outlines the function of each switch. For correct operation, set the required switch settings before powering the unit. Fault Detection...
OPTICAL SYSTEMS DESIGN 2.2.7 FITTING SFP CONNECTORS Care should be taken when inserting/removing the SFP connectors from the SFP port as SFP modules are Electrostatic (ES) sensitive and Electrostatic Discharge (ESD) precautions should be taken when installing. Ensure that the SFP is fully engaged and latched into position.
OPTICAL SYSTEMS DESIGN OSD2151 OPERATION This section outlines the OSD2151 connections and switch settings. Read this section carefully for trouble free set up and operation. There are two possible configurations for the OSD2151 namely Single Unit Configuration and Dual Unit configuration.
OPTICAL SYSTEMS DESIGN The following tables outline the recommended switch settings for the OSD2151. Any changes in switch settings require power up to take effect. Table 5: CONFIGURATION WITH LLF ENABLED Configurations Case1 Case2 Case3 Case4 Switch Setting 1. LLF detects fiber &...
OPTICAL SYSTEMS DESIGN Examples Figure 12 is an example of a copper connection loss. The OSD2151 will detect that there is no copper connection received and then disable the transmission to the fiber port. The 1000Base-X switch will thus be notified that there has been a copper link loss.
OPTICAL SYSTEMS DESIGN 3 MAINTENANCE INTRODUCTION The following section outlines the fault-finding procedure for the OSD2151 modems. Please take note of the following: Personnel without appropriate training should not attempt any maintenance except that outlined ▲ below. If further maintenance is attempted you are warned that every care should be taken to ensure that ▲...
