OK, I am reading right now description for Trendnet Mini-GBIC Features:
--------------------------------------------------------------------
(TEG-MGBSX, TEG-MGBS10, TEW-MGBS40, TEW-MGBS80)
Compliant with IEEE 802.3z Gigabit Ethernet and Fiber Channel Standards
Industry standard SFP package
Duplex LC connector
1.0625Gbps Fiber Channel Compliant
1.25Gbps Gigabit Ethernet Compliant
--------------------------------------------------------------------
So, I guess that 100Mbit and 1000Mbit is not set in stone and you can
actually achieve higher speeds than "standard".
BTW:
1 megabit = 106 = 1,000,000 bits which is equal to 125,000 bytes.
100 megabit = 12,500,000 bytes = 12,5MB
Or I am wrong?
