Knowledge in one place.
The DM936 D48CH14 (48 channels CH14–CH61) is the newest member of Datacom's DWDM ecosystem. This complete solution combines passive MUX/DEMUX, advanced optical amplification with EDFA (Erbium Doped Fiber Amplifier) and RAMAN modules, chromatic dispersion compensators (DCM), optical protection cards (OPS), and high-capacity DCI (Data Center Interconnect) platforms.
High Density with Modular Architecture
Today's optical networks require solutions capable of expanding fiber transmission capacity while ensuring operational simplicity and a predictable evolution path. In this context, Datacom's DM936 line was developed to enable modular expansion of DWDM links, meeting different stages of network maturity—from metropolitan structures to longer-range regional systems.
The new DM936 D48CH14 expands the passive multiplexer family, adding 48 DWDM channels (CH14 to CH61, according to the ITU-T G.694.1 grid) in a 1U module for installation in standard 19-inch racks. Featuring LC/UPC connectors and a dual-fiber uplink, the solution enables transmission of up to 480 Gbit/s per fiber pair using 10 Gbit/s SFP+ optical modules in each channel, enabling high-density point-to-point links with excellent utilization of existing optical infrastructure.
Features:
The DM936 family includes 8-, 16-, 32-, and 48-channel versions, with single- or dual-fiber operation options. All models follow the same mechanical and connectorization concept, simplifying field standardization and reducing deployment and maintenance time.
Optical Amplification and Compensation for Longer-Range Links
For applications requiring longer links or requiring optical loss and dispersion compensation, Datacom offers complementary modules. The DM936 EDFA is an optical amplifier with 20 dBm aggregate output power, designed for the 1535nm to 1565nm band. The module can be used to stably increase the range of DWDM links, allowing for distances of up to 80 km with 8-, 32-, or 48-channel MUX/DEMUX.
For even greater distances in specific configurations, the DM936 DCM40, a passive chromatic dispersion compensation module, can be used in conjunction with the amplifier. In systems with an 8-channel MUX/DEMUX, the combination of both modules can extend the range to up to 110 km.
These additional optical elements enable gradual network expansion without structural changes to the original design, maintaining the coherence of the Datacom DWDM ecosystem.
Integration with DCI platforms for high-capacity links
When demand evolves to rates of 100 Gbps to 400 Gbps per channel, integration is possible with the DM4920 platform, Datacom's DCI solution. This system supports transponders of up to 400 Gbps and an aggregate capacity of up to 1.6 Tbps per chassis.
The DM4920 is designed to operate with specific models of the DM936 line, such as the DM936 D8CH33 and the new DM936 D48CH14 (48 Channels). One of the great advantages of this architecture is the flexibility to combine different generations of services on the same link. For example, it is possible to maintain 10Gbps channels operating alongside new 400Gbps channels over the same MUX/DEMUX, ensuring the initial investment is preserved. This coexistence requires careful planning of the link's power budget to ensure optimal performance for each service, allowing for gradual network evolution. See an example:
Conclusion
Datacom's DWDM line offers a complete set of optical solutions to expand transport network capacity, combining high channel density, modular architecture, and full integration between passive and DCI layers.
With the new DM936 D48CH14, the company expands expansion possibilities in metropolitan and regional links, reinforcing its commitment to high-performance solutions, standardization, and operational efficiency for providers and operators across the country.
