Eska™ Mega
Eska™ MEGA - for Digital Home Appliance Interface
- Mitsubishi Rayon's original high bandwidth POF for consumer market developed in 1994.
- Recognized as a standard by ATM Forum and IEEE1394.
- Expected to be utilized as a PMD for Digital Home Appliance Interface.
Characterisitics
- Low NA of 0.3, Bandwidth of 230Mbps/50m
- Good against repeated bending
- Compliant with ATM standard
- Compliant with IEEE1394.b (S200) document specification
- Best suited for digital home appliances (S400/20m).
Can be utilized with ATM-LAN, 100Base, IEEE1394 (100, 200Mbps), PBX, and High speed FA interface.
Red line below is the shorter than red line above . These two lines show optical transmission time.
The difference between straight line(not shown) and red line is smaller in Low NA optical fiber than that of conventional NA optical fiber.
This means Low NA optical fiiber has smaller dispersion of transmission time.
That is why Low NA optical fiber is superior in bandwidth than conventional NA optical fiber.
