Rub the salmon with 1 tablespoon of the brown sugar.  Sprinkle with 1 teaspoon of the lemon pepper and 1/2 teaspoon of the garlic powder.  Rub the seasoning into the fish.

Combine the soy sauce and olive oil in a small saucepan. Stir in the remaining brown sugar, lemon pepper and garlic powder, as well as the ginger.  Place over medium heat and bring to a simmer.  Let the mixture simmer until the sugar has dissolved.  Remove from the heat and stir in the orange juice.

Place the fish and the marinade in a large ziplock bag.  Refrigerate overnight, or at least 4 hours.

Line a baking sheet with foil.  Preheat the broiler. Place the fish on the baking sheet, reserving the marinade.

Broil the fish for 2 minutes, then baste with the reserved marinade, then broil for 2 additional minutes.  Turn the fish over and broil until the fish flakes easily, about 4 more minutes.  Watch the salmon carefully while broiling, as the marinade on the baking sheet can start to smoke because of the sugar.

Remove the fish from the oven and allow to sit for 5 minutes before serving.
