10GBaseSR
B.
10BaseT
C.
100BaseFX
D.
1000BaseT
Explanation:
10GBASE-SR (“short range”) is a port type for multi-mode fiber and uses 850 nm lasers. Its
Physical Coding Sublayer 64b/66b PCS is defined in IEEE 802.3 Clause 49 and its Physical
Medium Dependent PMD in Clause 52. It delivers serialized data at a line rate of 10.3125 Gbit/s.
