Product Highlights
1. 80km Long-Haul 10G Solution with High Link Budget
- Enriched: Engineered for extended-reach applications, this module delivers stable 10Gbps connectivity up to 80 km over standard Single-Mode Fiber (SMF). Featuring a robust 24 dB link budget, it offers excellent tolerance to fiber loss, making it highly suitable for challenging network environments with multiple patch cords, splices, or variable fiber quality.
2. Premium Uncooled 1550nm EML Transmitter & High-Sensitivity APD ReceiverEnriched
- Optimized with a premium cooled 1550nm EML transmitter and an advanced Avalanche Photodiode (APD) receiver architecture. This combination is specifically designed to bridge extreme distances without intermediate optical amplifiers by capturing deeply attenuated optical signals over long-haul fiber paths.
3. 10 Gb/s Carrier-Grade Speed & Wide Standard Compliance
- Enriched: Supports continuous data rates from 9.95 Gb/s up to 10.31 Gb/s, satisfying strict transmission criteria for 10G Ethernet (10GBASE-ZR), SONET/SDH, and OTN backbone standards, ensuring smooth integration into carrier-grade infrastructures.
4. Industry-Standard LC Duplex Interface for Simple Deployment
- Enriched: Utilizes a universal LC duplex connector that is natively compatible with standard single-mode fiber networks, patch panels, and optical distribution frames. This eliminates the need for proprietary cabling systems and simplifies on-site hardware deployment.
5. Compact SFP+ Form Factor with Integrated DDM/DOM Diagnostics
- Enriched: The compact SFP+ form factor supports high port density in modern switches and routers, enabling efficient scaling of 10G uplinks without consuming excessive rack space. It includes a 2-wire serial interface (SFF-8472) providing real-time diagnostic tracking of internal temperature, voltage, laser bias, and precise TX/RX optical power.
