850 nm RFL - 4700MHz•km (3.5dB/km)
1300 nm - 500MHz•km (1.5dB/km)
✔✔Modal Distortion - ✔✔A light distortion problem unique to MMF fiber-optic cable.
Happens when light signals are sent at the same time.
✔✔chromatic dispersion - ✔✔The broadening of a pulse due to different propagation
velocities of the spectral components of the light pulse. Begins at the light source
✔✔Modal Bandwidth is described in terms of... - ✔✔(MHz)(km)
✔✔Ferrule
Key
Latching Mechanism - ✔✔flat or pre-radiused end
assures consistent connector orientation within couplers
locks in place
✔✔Straight Tip (ST) - ✔✔One of the most common fiber-optic connectors, similar in
style to the BNC connector in coax
✔✔subscriber connector (SC) - ✔✔A square snap coupling for fiber-optic cable, about
2.5 mm wide, used for cable-to-cable connections or to connect cables to network
devices. It latches with a push-pull action similar to audio and video jacks.
✔✔Small Form Factor (SFF) - ✔✔LC and MU
✔✔an example of array connectors... - ✔✔MPO
Can terminate 6-72 optical fibers into a single ferrule
✔✔Ohm's Law - ✔✔V=IR
