Coherent transponder Service Boards
Transponder Service Card LC-MP100-II - 100G (QSFP28 to CFP-DCO)
Coherent optical module 100G CFP (DCO)
The 100G CFP Coherent Optical Module (DCO) is designed to operate over dual fibre optical cable. On the transmit side, the module converts 25.78 Gbps (CAUI-4) or 27.95 Gbps (OTL4.4) electrical input channels into a single Single Lambda 100G optical signal. The module has a minimum guaranteed optical budget of 18.5 dB, which in most cases is sufficient to reach a distance of 80 km without signal amplification (with signal amplification, the module can reach distances up to 2400 km). The transceiver supports real-time DDM/DOM optical link diagnostics. In addition, it has an in-built generator and Line & Client PRBS checker to help diagnose and test memory status. The module has a dual LC connector facing the line side. On the host side, there is a 148-pin CFP2 MSA compatible connector.
Muxponder Service Card LC-MP200-II- 200G (2xQSFP28 to CFP2-DCO)
Coherent optical module 200G CFP2 (DCO)
The 200G CFP2 coherent optical module (DCO) is designed to operate over dual fibre optical cable. On the transmit side, the module converts 25.78 Gbps (CAUI-4) or 27.95 Gbps (OTL4.4) electrical input channels into a single 100G/200G Single Lambda optical signal. The transceiver has a minimum guaranteed optical budget of 18.5 dB, which in most cases is sufficient to reach a distance of 80 km without signal amplification (with signal amplification, the module can reach distances up to 1000 km (200G). The coherent module supports the PM-16QAM light signal modulation method for 200G speeds. The transceiver provides real-time diagnostics of the DDM/DOM optical link. In addition, it has a built-in Line & Client PRBS generator and checker to help diagnose and test memory status. The module has a dual LC connector facing the line side. On the host side, there is a 104-pin CFP2 MSA compatible connector.
Muxponder Service Card LC-MP400-II - 400G (4xQSFP28 to CFP2-DCO)
Coherent optical module 400G CFP2 (DCO)
The 400G CFP2 Digital Coherent Optics (DCO) transceiver provides multi-speed coherent signal transmission for data centre interconnection as well as metro and long distance backbone applications. On the host side, the module supports a variety of signal types including 100GE, 200GE, 400GE, OTU4 and OTUCn (FlexO). On the line side, 100G, 200G, 300G, and 400G interfaces with various modulation formats and forward error correction (FEC) codes. Multiple 100G clients can be multiplexed onto a single 200G, 300G or 400G line-side interface. The optical transceiver is RoHS and CFP MSA CFP2 equipment specification compliant with the extensions specified in the OIF CFP2-DCO implementation agreement.

Coherent transponder line cards and optical modules are essential components of DWDM systems, enabling reliable and stable long-distance data transmission over fiber-optic lines. They minimize signal loss and ensure high connection quality even at ultra-high transmission speeds.
Features and Advantages of DWDM Optical Modules and Line Cards
DWDM transceiver line cards and optical modules offer a number of key benefits:
- high data transmission density – support simultaneous transmission of hundreds of channels over a single optical fiber;
- long-distance transmission without signal loss – thanks to EDFA optical amplifiers and service boards, data can be transmitted over thousands of kilometers without the need for intermediate regeneration;
- support for high speeds – coherent transponders support speeds up to 400 Gbps and beyond;
- compatibility with various fiber types – work with nearly all fiber types, including PON systems.
Additionally, their modular architecture allows flexible network scaling by replacing or adding components without complex modifications.
Where DWDM Optical Transceiver Modules Are Used
DWDM line cards and optical transceivers are widely used across various sectors. Most commonly, they are deployed in backbone and metropolitan communication networks, as well as in data centers, where channel redundancy and high fault tolerance are essential.
How to Choose a DWDM Optical Module
When selecting a line card or DWDM optical module, consider the following key factors:
- Data transmission speed – e.g., 100G, 200G, 400G or higher, depending on network requirements;
- Equipment compatibility – ensure seamless integration with chassis, line cards, and other hardware;
- Fiber type and transmission distance – use multimode fiber for short distances and single-mode for long-distance transmission;
- Number of channels and frequency range – determine spectral efficiency and channel capacity;
- Diagnostics and monitoring features – allow real-time network health monitoring and troubleshooting.
