WBM-20 is a Coarse Wavelength Division Multiplexing (CWDM) system that delivers up to 8 channels and 20Cbit/s over a single fiber pair. Its rack-mountable 19 in. chassis supports hot swappable modules to make it an affordable and scalable solution for large enterprises and service providers.

The WBM-21 is a Compact (1.5U) 19" rack-mount, managed Small Form factor Pluggable (SFP) media connect WDM system, which delivers up to 8 channels (CWDM or DWDM) with a total bandwidth of 20Gbps over a pair of fiber strands for distances of up to 120Km.

The ST-M1 series are compact SDH multiplexers with STM-1 optical interfaces. The 1U box ST-M1-B1 provides up to 8/16/21 E1 tributaries.The 1.5U box ST-M1-B1 Plus provides versatile tributary interfaces: up to 63 E1/T1 and up to 3 E3/T3. All interfaces are fully compliant with the relevant ETSI standards and ITU-T Recommendations.
