ETERN Optoelectronics SFP28 BIDI (Single-Fiber Bidirectional) Series
The ETERN Optoelectronics 25GBASE SFP28 BIDI portfolio is engineered for high-density, low-power 25 Gigabit Ethernet connectivity. By utilizing Bi-Directional (BIDI) technology, these modules enable simultaneous transmit and receive signals over a single strand of standard single-mode fiber (SMF), effectively doubling your fiber plant capacity.
Features and Benefits
- Single-Fiber Efficiency: Reduces fiber cabling costs by 50% compared to traditional dual-fiber solutions.
- Wide Reach Range: Comprehensive support for 10km (LR), 40km (ER), and 80km (ZR) distances.
- Precision Wavelengths: Utilizes 1270nm/1330nm or 1295nm/1309nm pairings to ensure zero interference.
- Industrial Reliability: Available in Commercial (0°C to 70°C) and Industrial (-40°C to 85°C) temperature grades, certified for variety brand equipment.
Operational Note: BIDI transceivers must be used in pairs. For example, a 1270nm-TX/1330nm-RX module (Upstream) must be connected to a 1330nm-TX/1270nm-RX module (Downstream).
