Power and Environmental Savings
OLS vs. Traditional LAN Architectures
• Once the equipment energy consumption is totaled, the following
formula can be used to calculate cost savings for commercial
power between traditional copper/fiber and OLS:
– Equipment wattage x 1.1 x 2/1000 = KW
– KW x 8760 hrs per year = KWH
– 0.107€ (European Average cost per KWH) =
annual energy costs for the equipment
• Copper Solution example (700 users)
– MDF has a router, servers, an analog gateway and a LAN switch
– Each floor is equipped with multiple LAN switches and gateways
Combined AMPS = 229
Combined Watts = 82,368
Combined BTU = 52,948
• OLS Solution example (700 users)
– MDF has the same level 3 WAN router, an Optical Line Terminal
(OLT), an edge router, and DC power distribution units
– Each floor is equipped with low power consumption Optical Network
Terminals (ONTs) at each user and all other equipment is passive
Combined AMPS = 279
Combined Watts = 24,088
Combined BTU = 41,330
• The results – copper solution uses 50 AMPS less than OLS, however:
– OLS saves 58,280 watts over copper solution (70%)
– OLS saves 11,618 BTUs (22%)
Annual energy cost for copper solution: 77,205€
Annual energy cost for OLS solution: 22,578€
Projected Savings: 54,627€ year-over-year savings
