The LC MIL connector can be used in temperatures as low as -40°C and up to 75°C.

These are different terminologies. Tight packed refers to a cable construction where there is a large amount of aramid yarn under the primary cable jacket which improves crush resistance but does not allow for the inner fiber subunit to move with relation to the outer cable jacket. This is commonly seen in tactical or military spec cables. Tight buffered fiber refers to the bonding of the buffer material to the glass optical fiber, creating a bond between the glass and buffer. This is usually 900um or 600um in diameter. Tight buffered fiber can be found in standard cordage as well as tight packed cordage. In standard cordage, the inner subunit can piston with relation to the outer jacket, unlike with tight packed cable.

Yes, by adding a simple clip, simplex connectors can be joined to form a duplex connector.
