Why Choose Tunable 4x28G DWDM CFP module for metro network

Why Choose Tunable 4x28G DWDM CFP module for metro network?

Menara Networks announces the new product of tunable DWDM CFP 100G MSA module. The tunable DWDM CFP 100G module supports the industry’s lowest cost 100G DWDM transport solution for metro applications. The DWDM CFP module provides interoperability with installed 100GHz and 50GHz DWDM systems for application on carrier backhaul and data center interconnect.

The DWDM CFP MSA compliant module supports both CAUI and OTL-4.10 electrical interfaces, allowing for Forwarding Error Correction addition enabling transmission distances up to 400km. Power consumption is contained below the MSA limits, allowing the DWDM CFP use in dense Ethernet switch and IP router line cards and DWDM transport systems. Utilization of direct detection technology provides a significant cost advantage over current coherent solutions, allowing carriers to accelerate 100G deployments in the metro network with a shortened Return on Investment time period.
Immense amounts of backhaul traffic from ISPs and carrier aggregation points drive the customer demand for 100G transport in the metro network, this 100G DWDM CFP solution provides a low-cost 100G transport solution fitting the needs of these applications.

In this blog, we'll take three to compare tunable vs. fixed-wavelength Optics and tell why choose tunable DWDM CFP module for metro network.

Wavelength Adaption
The wavelength is fixed when DWDM is designed, so each module can only be used at the required network node. For example, you can only connect an SFP+ transceiver with C21 wavelength to the port of C21 wavelength. With the tunable SFP+, network operators can use DWDM to connect any ports on the same MUX through fiber cables, since the transceiver can be tuned to adapt to different wavelengths.

Reduction of Inventory
Fixed DWDM optical modules are traditionally deployed in networks that require little channel change or addition to avoid unnecessary replacements. This often requires stocking each channel your network requires, reducing flexibility by tying up the budget in a lesser spare quantity. When you need more wavelength flexibility, tunable DWDM optical transceivers can serve as an excellent spare unit since they can be modified to fit any need on the fly. It’s far more cost-effective and timely to tune an optic from stock as needed instead of stocking up to 40 different channel transceivers.

Long-Term Benefits
While the cost of a fixed-wavelength transceiver is lower than that of a tunable DWDM module, the long-term effects are that AddOn’s tunable optics will likely save money and benefit your business costs greatly. A 10G DWDM system with hundreds of nodes that use different wavelengths requires a large variety of backup SFP+ transceivers to avoid downtime, in turn increasing operating costs. When tunable optics are used in place of fixed-wavelength SFP+ transceivers, network operators benefit from reduced on-hand inventory, also making it easier to accommodate changing network demands.
