Notes:

1.

For SONET/SDH applications the jitter specifications are defined as per [9].

2.

If the CDRs are in bypass mode, the Tx jitter is compliant to the specification defined in [4].

General Specifications

Bit rates: CDR’s lock at 8.5Gb/s, and from 9.83Gb/s to 11.3168Gb/s bit rates. With

CDR’s in bypass mode 6.144Gb/s CPRI is also supported.

Notes:

Tested with a 2

2.

Assuming that the optical link loss due to fiber attenuation is 0.38dB/km.

3.

The actual min. link length may differ as it is affected by the receiver overload limit.

4.

Assuming FTLX1772M3BCL transceivers on both side of the link. If a PIN receiver is on the other

side of the link, the optical link budget may not be enough to support 40km of fiber attenuation loss.
