Performance Monitoring

The performance monitoring capabilities of the transponder card provide support for both transparent and

nontransparent signal transport. For SONET/SDH signals, standard performance monitoring, threshold-crossing

conditions, and alarms are supported per Telcordia GR-253, GR-474, and GR-2918; ITU G.828; and ETS 300 417-

1 standards. The digital wrapper channel is monitored per G.709 (OTN), G.8021. Optical parameters on the client

and DWDM line interfaces support loss of signal (LOS), laser bias current, transmit optical power, and receive

optical power. Calculation and accumulation of the performance-monitoring data are in 15-minute and 24-hour

intervals as per G.7710.

A detailed list of performance monitors is given in Table 8.

The transponder card incorporates faceplate-mounted LEDs to provide a quick visual check of the operational status

of the card. An orange circle is printed on the faceplate, indicating the shelf slot in which you can install the card.

Regenerator Configuration

The Cisco 40-Gbps Full-Band Tunable CP-DQPSK Transponder Card supports the OTU3 Regeneration function.

You can configure two cards to work in back-to-back mode, allowing the transponder to perform the OTN O-E-O

regeneration function as depicted in Figure 6.

Figure 6. OTU3 Regeneration Configuration for 40-Gbps Full-Band Tunable CP-DQPSK Transponder Card

The client can be OC768, STM-256, or OTU3. Regeneration is performed through the OTU3 client-to-client

interconnection, where OTU3 overhead is terminated, allowing ODU3 to transparently pass through. GCC0 are

properly terminated, and GCC1 and GCC2 are properly passed through.

In case of failure on one side, ODUk-AIS is generated and propagated and an OTUk-BDI is sent back as defined

by the ITU G.709 standard.

Application Description

The Cisco ONS 15454 MSTP 40-Gbps Full-Band Tunable CP-DQPSK Transponder Card adds the capability to

cost-effectively transport 40-Gbps services. Two main applications are expected.

●

40-Gbps router interconnection for business services and research networks: Cisco research indicates that

the total volume of worldwide IP traffic is doubling every two years, requiring an increase in transfer rate

from 10 Gbps to 40 Gbps. The transponder solution aims to provide DWDM interconnection between 40-

Gbps interfaces among routers across DWDM metro, regional, or long-haul networks. The advanced

modulation scheme is designed to cope with long-distance application performance requirements, allowing

the extension of 40-Gbps service over 1500 km.

●

OTU3 links in national carrier backbone networks: OTN technology is vital to backbone carrier networks. It

is the baseline method that offers intercarrier or interdomain transfer to any next-generation transport

network at 2.5-Gbps (OTU1), 10-Gbps (OTU2), or 40-Gbps (OTU3) rates. The Cisco 40-Gbps Full-Band

Tunable CP-DQPSK Transponder supports a fully standard OTU3 interface that can cope with signals from
