Etern Optoelectronics officially announced the landmark release of its new WDM optics series—the 25G SFP28 CWDM BiDi Transceiver. The product has successfully entered the New Product Introduction (NPI) phase and is actively being delivered to global tier-1 customers for network integration.
Technical Specifications & Key Features:
- Form Factor: Hot-pluggable SFP28 MSA compliant design ensuring seamless equipment interoperability.
- Optical Interface: Simplex LC connector topology for maximum fiber plant efficiency.
- Wavelength Spectrum: Spanning CWDM channels from 1270nm to 1370nm lambda grid.
- Co-Wavelength BiDi Innovation: Utilizes the exact same wavelength (lambda) for both the transmitter (Tx) and receiver (Rx) chains simultaneously.
- Flexible Link Budgets: Supports link distances up to 10km over Single-Mode Fiber (SMF) via the PIN photodiode version, and extends up to 40km utilizing the high-sensitivity APD photodiode variant.
Micro-Circulator Integration & Patent-Pending Design
This breakthrough co-wavelength single-fiber bidirectional operation is driven by the internal integration of a proprietary micro-circulator. Engineered by ETERN's specialized passive optical components team, this ultra-compact component design has successfully rendered single-frequency full-duplex transmission a reality. This represents another major technical milestone in optical manufacturing for Etern Optoelectronics, with fundamental invention patents currently under formal review.
Doubling Density for 5G Fronthaul & CATV Networks
By exploiting this co-wavelength single-fiber bidirectional technology, the transmission density of existing 25G CWDM infrastructures is instantly doubled. This optimization unlocks a highly agile roadmap for next-generation 5G fronthaul network architectures, high-capacity CATV access distribution, and enterprise CWDM enterprise core topologies. ETERN's continuous innovation is dedicated to making complex physical layer networks more simplified, robust, and cost-efficient.
