High Density CWDM And Compact CWDM Multiplexer 2 Channels To 18 Channels

Feature: Breakthrough Ultra-Low Insertion Loss (CCWDM vs. Traditional CWDM)
Pain Points Solved/Value Benefits: CCWDM, with its cascaded optics design, achieves a qualitative leap in insertion loss control. For example, in a fully configured 18-channel module, the maximum insertion loss of traditional CWDM is 4.2 dB, while our CCWDM is only an extremely low 2.5 dB. In 4-channel and 8-channel configurations, the CCWDM insertion loss is even lower, at an astonishing 0.8 dB and 2.0 dB respectively. This saves extremely valuable optical power budget for your 5G fronthaul and metro ring networks, significantly extending repeaterless transmission distances.

Feature: Ultra-Compact Footprint
Pain Points Solved/Value Benefits: Traditional 18CH CWDM typically requires a large LGX box or rack space. Our 18CH CCWDM module measures only 53.50 × 50.00 × 6.00 mm, while the 4CH/8CH module is even smaller at 45 × 25 × 6 mm. This extremely compact size, less than a quarter the size of traditional modules, perfectly fits the confined spaces of 5G small cells, high-density fiber optic distribution boxes, and edge computing nodes.

Features: Glue-Free Metal-Bonded Packaging
Solved Pain Points/Value: Completely eliminates the use of epoxy resin and other organic adhesives in the core optical path area. This not only fundamentally eliminates optical path misalignment caused by adhesive aging or moisture, but also ensures decades of long-term carrier-grade reliability for the components in environments ranging from -5°C to 65°C (and even more demanding conditions).

Features: High channel isolation and excellent in-band flatness
Solved Pain Points/Value: Adjacent channel isolation ≥30 dB, non-adjacent channel isolation ≥40 dB, combined with a wide channel spacing of 20 nm and a channel passband of ±6.5 nm. This gives the system extremely strong resistance to wavelength drift, allowing signals from inexpensive lasers without temperature control to be perfectly isolated and transmitted even in environments with drastic outdoor temperature differences, completely eliminating channel crosstalk.

Feature: Customizable Monitor Port
Solved Pain Points/Value: Optional integrated special monitor port allows operations teams to access instruments for real-time network health checks without interrupting the 5G bearer network or CATV live streaming services.
