NP200/NP200E

Basic function

NP200/NP200E:

• 80 x ODU0/80 x ODUflex/40 x ODU1/10 x ODU2/10 x ODU2e/2 x ODU3/1 x ODU4<->1 x OTU4
• Supports mixed transmission of ODU0, ODU1, ODUflex, ODU2 and ODU2e signals.

NP200:

• Multiplexes and demultiplexes two optical signals. That is, the NP200 board receives one OTU4 optical signal from the NP200E board and converts its own OTU4 optical signal and the received OTU4 optical signal into one multiplexed optical signal.

Cross-connect capabilities

Supports the cross-connection of 80 channels of ODU0/ODUflex signals or 40 channels of ODU1 signals or 10 channels of ODU2/ODU2e signals or 2 chanels of ODU3 signal or one chanel of ODU4 signal between the NP200/NP200E and the cross-connect board.

OTN function

• Supports the OTU4 interface on the WDM side.
• Supports the OTN frame format and overhead processing by referring to the ITU-T G.709.
• OTU4 layer: supports the SM function.
• ODUk (k=0, 1, 2, 2e, 3, 4, flex) layer: supports the PM and TCM function, and PM and TCM non-intrusive monitoring functions.

WDM specification

Supports ITU-T G.694.1-compliant DWDM specifications.

ESC function

Supported

PRBS function

Supports the PRBS function on the WDM side.

LPT function

Not supported

FEC coding

SDFEC2

Alarms and performance events monitoring

• Monitors BIP8 bytes (Bursty mode) to help locate line failures.
• Monitors parameters such as the bias current, temperature, and optical power of the laser.
• Monitors OTN alarms and performance events.

ALS function

Not supported

Latency measurement

Supported

Test frame

Not supported

IEEE 1588v2

Not supported

Physical clock

Supported (ODU0/ODU1/ODU2/ODU2e/ODU3/ODUflex)

Protection scheme

• Supports ODUk SNCP.
• Supports tributary SNCP protection.

Over-temperature protection

If the temperature of a board exceeds the upper threshold and services are affected, the board will automatically reset the key chips to prevent a board damage.

Loopback

• Supports system-side channel inloops and outloops.
• Supports WDM-side inloops and outloops.
