High-Density Fiber Management for Enterprise Networks
Telhua's COSH-144 4U Left Swivel Module revolutionizes fiber optic infrastructure by combining splicing and patching in a single, space-efficient unit. Designed for data centers and enterprise networks requiring high port density and rapid deployment, this solution addresses critical pain points in modern fiber management.
Key Features and Benefits
Optimized Space Utilization
The 4U chassis accommodates 144 ports while maintaining full accessibility through the innovative left-swivel design. This configuration maximizes rack space efficiency, allowing more connections per square foot compared to traditional patch panels.
Integrated Splicing and Patching
Eliminate separate splicing trays and patch panels with this unified solution. The combined design reduces installation time by up to 40% and minimizes points of failure in your fiber network.
Enhanced Reliability and Accessibility
The swivel mechanism provides full front access to all connections without disrupting adjacent equipment. This design significantly reduces maintenance downtime and improves overall network reliability.

Telhua Engineer's Tip
For optimal performance when connecting to an ethernet switch with fiber port, pre-terminate your fiber cables using angled physical contact (APC) connectors for single-mode applications. This reduces back-reflection by up to 70% compared to UPC connectors, significantly improving signal integrity in high-speed networks. When planning your fiber management, allocate 20% additional capacity in the COSH-144 module for future expansion and maintenance loops.
Standards and Compliance
The COSH-144 module meets or exceeds all relevant industry standards, including IEC 61754 for fiber optic connector interfaces, TIA/EIA-568 for telecommunications infrastructure, and RoHS directives for environmental safety. This ensures compatibility with existing infrastructure and future-proofs your investment.
