D1 |
Polarization-maintaining fibre suitable for use at 980 nm |
This category of polarization-maintaining fibre is optimised for polarization-maintaining ability in the 980 nm region. This fibre is used for erbium-doped fibre amplifier. |
|
D2 |
Polarization-maintaining fibre suitable for use at 1 310 nm |
This category of polarization-maintaining fibre is optimised for polarization-maintaining ability and connection property of category B fibres in the 1A 310A nm region. |
|
D3 |
Polarization-maintaining fibre suitable for use at 1 550 nm |
This category of polarization-maintaining fibre is optimised for polarization-maintaining ability and connection property of category B fibres in the |
