Standard Requirements for Wiring Color of Power Cabinets
The mandatory colors for power wiring in the National Electrical Code (NEC) are Green, Bare, or Green/Yellow (a yellow stripe or band on green) for the protective ground (PG), and White (or alternatively Gray) for the neutral wire. Colour identification by using common colours is permitted, provided that there is no risk of confusion and no GREEN or YELLOW is used, except in the two-colour combination GREEN-YELLOW. When using color codes for the identification of current conductors, it is recommended to use the following. Wiring color codes vary by region and are designed to meet local standards and regulations for AC (Alternating Current) single-phase, AC three-phase, and DC (Direct Current) systems. By using standard or custom color codes, technicians can install, inspect, and repair systems quickly and reliably. Customers occasionally inquire about the use of wire color versus other identification methods.

Optical module transmit power decreases
If the transmit power is much lower than the transmit power specification of the optical module, possible causes are as follows: Optical bores of the optical module are contaminated. Use a cotton swab to clean the optical bores. Cover idle optical modules with. Optical fiber loss usually decreases with wavelength lengthening, 850nm loss is less, 900~1300nm loss becomes higher; and 1310nm becomes lower, 1550nm loss is the lowest, and loss above 1650nm tends to increase. So 850nm is the so-called short wavelength window, and 1310nm and 1550nm are long. Use an optical power meter to measure the transmit power of the optical module. Use a cotton swab to clean the. Transmitter power characterizes the average optical power output from the laser under rated conditions, while receiver sensitivity indicates the minimum detectable power required to maintain a low bit error rate. Many sfp modules also have DOM/DDM, which lets you see digital diagnostic monitoring data on network equipment.
