[1] Measured without connectors. For other wavelengths, please contact us.
[2] Cross talk is measured at 500kHz, which may be degraded at the higher repeat rate.
[3] It is defined as the rising or fall time between 10% and 90% of optical intensities.
[4] Defined at 1310nm/1550nm. For the shorter wavelength, the handling power may be
reduced, please contact us for more information.
[1b] NPLC version available for high power and low loss that incorporating fiber core
enlargement (expensive).
