* Minimum Laser Effective Modal Bandwidth (EMB)
** For backward compatibility to LED based systems, overfilled launch(OFL)
ˆ 1310 nm CWDM lasers (10GBASE-LX4)
1. Reach assuming 3.0 dB maximum cabled attenuation at 850 nm and 1.3 dB total connection and splice loss
2. Supports 220 meter 10GBASE-LRM distance, or 300 meter 10GBASE-LRM distance with 300 meter capable equipment
3. 3.5/1.5 dB/km maximum attenuation applies for DX-Series cables greater than 36 fibers, and for all DX-Series cables with armor (corrugated steel tape or interlocked armor) or any other secondary outer jacketing
4. 10 km for 1310 nm 1000BASE-LH, and 5 km for 1310 nm 1000BASE-LX
5. 10 km for 1310 nm 10GBASE-LR, and 40 km for 1550 nm 10GBASE-ER
6. Typical Mode Field Diameter at 1310 nm
Note: Many other fiber types, fiber bandwidth, and attenuation performances are available.
