UltraLAN 1G SFP BiDi Pair 20KM SM 1310/1510nm 24m

UltraLAN’s BiDi SFP transceivers are designed for high performance and cost efficiency. They support dual data rates of 1.25Gbps/1.0625Gbps and enable transmission distances of up to 20km over single‑mode fiber (SMF).

Product Composition
FP/DFB laser transmitter for stable optical output
PIN photodiode with integrated trans‑impedance preamplifier (TIA)
MCU control unit for diagnostics and performance management
Class I laser safety compliance
Compatible with SFP Multi‑Source Agreement (MSA) and SFF‑8472 standards

Key Features
Supports 1.25Gbps downstream bit rates
Bi‑Directional LC connector (single fiber, dual wavelength)
Hot‑pluggable SFP footprint for easy installation
Suitable for up to 10km SMF connections (rated for 20km maximum)
Low power consumption (<0.8W)
Digital Diagnostic Monitor Interface (DDMI) for real‑time monitoring
Very low EMI and excellent ESD protection

Important Note
These are BiDi (Bi‑Directional) SFP modules, transmitting and receiving on different wavelengths (Tx: 1310nm / Rx: 1510nm). They are only sold in pairs, as each side of the link requires a complementary module.
