3M Intros Coarse Wavelength Division Multiplexers and PLC Optical Splitters

3M (News - Alert), a provider of networking solutions, has introduced two new Coarse Wavelength Division Multiplexers (CWDM) designed to help cable operators increase capacity while reducing containing costs. The new families of optical components, which are unveiled at Cable-Tec Expo, boast the thinnest form factors available in the market.

The CWDM technology has the ability to increase capacity without adding new fiber. This is achieved by using different wavelengths of light to multiply the number of optical carrier signals on a single fiber. Another advantage of CWDM technology is that it enables bi-directional communication on the same strand of fiber.

“Cable operators using 3M CWDM to enable multi-wavelength technology can now cost-effectively extend capacity and bandwidth in fiber poor environments with the reliability of 3M products designed to meet and exceed Telcordia (News - Alert) GR-1209, GR-1211 requirements,” company officials said in a statement.

With the cost of deploying new fiber ranges between $10,000 and $70,000, the new CWDM solution offers a great cost savings to cable operators. They can leverage the multi-wavelength technology to extend capacity and bandwidth in fiber poor environments in a cost-effective way.

3M also introduced Planar Light Circuit (PLC) Optical Splitters that integrate with a broad range of architectures and platforms. The PLC splitters are designed for carriers looking to deploy RFoG or PON FTTH networks. They are available in many split ratios, with bare-fiber or connectors, including the commonly deployed: 1x2, 1x4, 1x8, 1x16, 1x32.

The use of PLC splitters in FTTH networks helps to reduce the number of feeder fibers originating from the head-end to the serving area.

The 3M PLC splitters are fully passive optical branching devices exhibiting uniform signal splitting for the most advanced optical networks. They are manufactured and tested to GR-1209/1221 requirements to ensure performance and reliability in harsh environments.

Both CWDMs and PLC Optical Splitters can be integrated into all 3M fiber closures, terminals and FDUs, enabling a complete solution for cable operators.

In a recent development 3M announced it is acquiring Ceradyne. The deal was valued at $35 a share, and works out to a total of $860 million. Ceradyne’s board has approved the offer. The transaction is expected to close during the Q4 of 2012 upon approval by regulators and shareholders.
