Page 4: Introduction
This document details the installation and operation of the Navicor 1550 Externally Modulated 1RU Transmitter (C-COR NA15T Series) and the Navicor 1550 Erbium Doped Fiber Amplifier or EDFA (C-COR NA25E Series). The transmitter converts RF signals to optical signals on optical fiber. The EDFA amplifies an input from several optical fibers and outputs it to one optical fiber. -

Page 10: Fiber Care And Cleaning
Fiber Care and Cleaning The fiber optic medium does not suffer from problems associated with copper-based coaxial cables, such as electromagnetic interference and increasing loss of signal power at higher frequencies and cable lengths. However, the ability of the optical fiber, a thin, flexible strand of silica glass, to enable light to travel through it with as little impedance as possible depends on the purity of the glass, the manner of its construction, and its care during handling, splicing, and installation. -
Page 11: Fiber Cleaning
Fiber Cleaning Using compressed air improperly on fiber cable connectors or bulkhead connectors can scratch the fiber endface or leave a residue and thereby degrade signal performance. Caution Dust caps do not keep connectors completely free of dust or contaminants. Perform the procedures below each time fiber is handled and connections are made. -
Page 12: Fiber Connectors
Fiber Connectors Before connecting fiber cable connectors to bulkhead connectors, use an optical power meter to ensure that the received optical power is within the specified range. Received optical power greater than the specified maximum level can damage forward optical receivers. 0.05 Caution FC connectors must have a keyway no wider than... -

Page 14: Unpacking
Examine all units for any damage due to transit. If damage is discovered, file a claim with the carrier immediately. Notify your C-COR representative as soon as possible. Product deemed defective by the original purchaser must be returned to C-COR prepaid in the original packing material (or equivalent) with a Return Material Authorization (RMA) from the C-COR Equipment Service Center (+1-814-231-4444). - Page 15 Unpacking MX0860 Revision B...

Table 5. Transmitter Controls and Indicators Item Label Function STATUS LED LED lights green to indicate that RF is present and that the transmitter is functioning normally with laser active. LED lights yellow (Minor Alarm) to indicate a parameter that will not cause damage or affect operation of the transmitter, but may be near an operational limit. - Page 19 Table 5. Transmitter Controls and Indicators (continued) Item Label Function VIDEO LED LED lights when in Video mode. In Video mode, the AGC accounts for power and carrier peak level changes associated with carrier modulated envelopes and maintains proper RF gain through the path to provide correct operation with actual carriers.
