Eska™ Mega - for digital home appliance interface
- Mitsubishi Rayon's original high bandwidth POF developed for the consumer market in 1994.
- Recognized as a standard by ATM Forum and IEEE1394.
- Expected to be utilized as a PMD for digital home appliance interface.
Characteristics
- Low NA of 0.3, bandwidth of 230Mbps/50m
- Withstands repeated bending
- Compliant with ATM Forum PHY-0079
- 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 shorter than red line above. These two lines depict optical transmission time.
The difference between the straight line (not shown) and red line is smaller in low NA optical fiber than in conventional NA optical fiber.
This means low NA optical fiber has smaller dispersion of transmission time, and therefore is superior in bandwidth to conventional NA optical fiber.
