Codecom’s passive optical networking range includes fully customisable DWDM multiplexers and PON coexistence WDM filters, both designed around a core principle: your network shouldn’t have to conform to an off-the-shelf product.

The 40 Channel DWDM Multiplexer combines up to 40 independent optical channels onto a single fibre pair using 100GHz ITU-T G.694.1 channel spacing — delivering high-density, high-bandwidth transport with no active electronics and no external power required. Channel labelling, monitor ports, channel spacing, and starting channel are all configurable to your deployment.

The Custom CeX coexistence filter takes the same philosophy to PON network upgrades, enabling GPON, XGS-PON, 10G-PON, NG-PON2, and RF video to run simultaneously on existing fibre without disrupting live subscribers. Unlike fixed off-the-shelf coexistence filters, the CeX is built to match your current services and upgrade path — whether that’s an XGS-PON overlay today or a staged migration toward 25G or 50G PON tomorrow.

Both products are available in 1RU, LGX, and CMD form factors, integrate directly into existing Codecom ODF and patch panel infrastructure, and are engineered to specification. Contact Codecom to discuss your requirements.
