Module 2.5 Flashcards
Single mode cables support data rates up to ___________ Gbps and cable runs of many kilometers, depending on the quality of the cable and optics.
100
There are two grades of SMF cable; ________ is designed for indoor use, while ______ is for outdoor deployment
OS1 and OS2
_______ has a larger core (62.5 or 50 microns) and shorter wavelength light (850 nm or 1300 nm) transmitted in multiple waves of varying length
MMF
MMF uses less _____________ and consequently is less expensive to deploy than SMF. However, it does not support such high signaling speeds or long distances as single mode and so is more suitable for LANs than WANs
expensive optics
62.5-micron cable is ____________________
OM1
while early 50-micron cable is ____________________
OM2
OM1 and OM2 are mainly rated for applications up to___________ Gbps and use LED transmitters.
1
__________________ these are also 50-micron cable, but manufactured differently, designed for use with 850 nm Vertical-Cavity Surface-Emitting Lasers (VCSEL), also referred to as laser optimized MMF (LOMMF).
