Which of the following is used for SONET connections and requires a wavelength of 1310nm?
The correct answer is C. 10GBASELW. 10GBASELW (Long Wavelength WAN) is specifically designed for SONET/SDH WAN connections and operates at a wavelength of 1310nm over single-mode fiber. The 'W' suffix indicates WAN/SONET compatibility. 10GBASESR uses 850nm for short-range multimode connections. 10GBASELX4 also…

Explanation
10GBASELW (Long Wavelength WAN) is specifically designed for SONET/SDH WAN connections and operates at a wavelength of 1310nm over single-mode fiber. The 'W' suffix indicates WAN/SONET compatibility. 10GBASESR uses 850nm for short-range multimode connections. 10GBASELX4 also uses 1310nm but is a LAN standard, not SONET-compatible. 10GBASECX4 uses copper twinax cabling rather than fiber.
