1310nm - ANSWERS-A commonly used fiber optic wavelength used in broadband
telecommunications with a loss of ~ .33dB/km.
1550nm - ANSWERS-A commonly used fiber optic wavelength used in broadband
telecommunications with a loss of ~ .25dB/km.
Used for optical links of 120km or greater.
CFR - ANSWERS-Code of Federal Regulations
Cable system rules published by the FCC and federal government.
CT - ANSWERS-Central Tube
The principle protective tube located inside of a fiber cable
CWDM - ANSWERS-Course Wavelength Division Multiplexing
A technique in which an increased number of different light signals are simultaneously
transmitted (e.g., typically 8 to 16) increasing data rates on fiber optics. CWDM offers a
, lower data rate than DWDM. Ratio of two power levels, P1 and P2, expressed
mathematically as dB =
10log10(P1/P2). Commonly used as an expression of gain or loss.
CLT - ANSWERS-Central Loose Tube
A fiber cable in which the coated fiber is located inside of an oversized protective tube
which is filled with optical gel.
dB - ANSWERS-decibels
Ratio of two power levels, P1 and P2, expressed mathematically as dB =
10log10(P1/P2). Commonly used as an expression of gain or loss.
dBm - ANSWERS-decibels milliwatt
Unit of power expressed in terms of wattage, defined as decibels relative to 1 mW.
Mathematically, dBm = 10log10(Px /1 mW), where Px is the power in milliwatts that is to
be converted to dBm. Commonly used as a metric for signal power measurements in
optical networks, microwave and other radio applications.
DFB - ANSWERS-Distributive Feedback Laser
A type of optical fiber laser where the active region of the device is periodically
structured as a diffraction grating.
DGD - ANSWERS-Differential Group Delay
Measured in pico seconds, the difference in propagation time between the two principal
states of polarization (PSP).
DoSS - ANSWERS-Director of Safety and Health
Person in charge of managing and overseeing Safety procedures with regards to fiber
cable manipulation, installation and maintenance
DS - ANSWERS-DownStream
