What is the difference between a 100G ZR DCO module and a traditional 100G optical transceiver?

A traditional 100G optical transceiver usually uses direct-detection technology, while a 100G ZR DCO module uses digital coherent optics with advanced modulation and FEC processing. Coherent technology provides better tolerance to dispersion and enables significantly longer transmission distances for metro and transport networks.

What transmission distance can this 100G ZR QSFP28 DCO module achieve?

The module supports up to 80km transmission without optical amplification under loss-limited conditions and can reach approximately 120km in dispersion-limited applications. Extended-reach configurations may support longer distances depending on network design and optical amplification.

Is this module compatible with DWDM networks?

Yes. The QSFP28 DCO transceiver features tunable C-band wavelength operation and supports 50GHz or 100GHz channel grids, making it suitable for DWDM systems that require flexible wavelength allocation.

What type of fiber is required for this coherent transceiver?

This module is designed for standard single-mode fiber (SMF), commonly deployed in telecom and carrier networks. Proper optical link budget calculation, dispersion analysis, and network planning are recommended for long-distance deployments.

Does this module support both Ethernet and OTN applications?

Yes. The transceiver supports 100GE CAUI-4 Ethernet interfaces as well as 100G OTN OTL4.4 host interfaces, allowing deployment in both packet networks and optical transport systems.
