==== Fiber run measurements, April 2024: ====


- From Nasmyth focus to top of pier needs measurement of exact route, but roughly 62.25 inches estimated

- From top of pier to bottom of pier: 4' 6"

- from bottom of pier to J3 junction box (concrete): 22' 3", including some estimate of service loop for azimuth motion

- from J3 junction box to J4 junction box : 98'

- from J4 junction box to J5 junction box : 25' 6"

- from J5 junction box to big box on wall of SDSS pier: 24'

- from big box to small junction box where conduit enters APOGEE raceway:  40' 4"

- from small junction box up to wall in MARVELS room:  21' (but may need additional if service loops are needed for tight turns, e.g. from building entrace through APOGEE room heading up


Total length from Nasmyth to MARVELS room 

- in inches :  62.25 + (4*12+6) + (22*12+3) + (98*12) + (25*12+6) + (24*12) + (40*12+4) + (21*12) = 2889.25

- in meters : 73.38 m total

MARVELS room wall length ~6 meters, so need additional depending on where spectrograph is located
