1, two switches on the fiber adapter how interconnection? Whether any equipment? What is there seems to hold the transmitter? 2, switchboard see these parameters :
Temperature (° C) -5-45
Working humidity 10% - 95%
Working height (m) 3000
Storage temperature (° C) -20-70
Storage humidity 10% - 95%
Storage height (m) 4500
Storage and work in highly What does this mean?
You think ah, a very clear among Chinese. Altitude of 3,000 meters below? The first issue, prawn
I have not yet in store over 4,500 high above the Eastern estimated certainly stimulate ~~~ ~ ~ PDH optical signal transmitted sites chant ~~`
Fiber Adapter two switches connected with it if the transmitter? Some higher than 3000m above sea level in Tibet's cities can not be used? Want to know
Fiber Jumper ~~~ not good on both sides of the joints, a variety of different ~~~ ~ ~ Perhaps most LC-ST or LC-SC with the jumper, two switches direct-mouth can, but only one wave Jumper LC I (then - I), the need for a jumper wiring box, which has coupler link, then even wave jumper, it can connect to another switch-mouth; A converter is also useful in transmitting the signals into optical signals, respectively. UTP and fiber converter ends. But this is 10 times lower than the rate of direct I know cisco 2955 switches can be created in the normal use of high altitude. Still at a very low temperature (minus the number of degrees) where normal use. However, such equipment generally is not long used. [ Closed window ]
