supports framing. Finally, the output signal is serialized and connected to the trunk front end with a

direct modulation laser. The trunk receive signal is converted into an electrical signal with an avalanche

photodiode (APD), is deserialized, and is then sent to the TADM framer and FPGA.

The MXPP_MR_2.5G is the same, except a 50/50 splitter divides the power at the trunk interface. In the

receive direction, there are two APDs, two SERDES blocks, and two TADM framers. This is necessary

to monitor both the working and protect paths. A switch selects one of the two paths to connect to the

client interface.

You must use a 20-dB fiber attenuator (15 to 25 dB) when working with the MXP_MR_2.5G and

MXPP_MR_2.5G cards in a loopback configuration on the trunk port. Do not use direct fiber loopbacks

with the MXP_MR_2.5G and MXPP_MR_2.5G cards. Using direct fiber loopbacks causes irreparable

damage to the MXP_MR_2.5G and MXPP_MR_2.5G cards.

The MXP_MR_2.5G and MXPP_MR_2.5G cards have several safety labels that provide laser radiation

and electrical shock warnings.

warning labels before working with these cards. The hazard level label warns the personnel against

exposure to laser radiation of Class 1M limits calculated in accordance with IEC60825-1 Ed.1.2.
