Information About QSFP-100G-LR-S
The QSFP-100G-LR-S operates at a 1310 nm optical wavelength and delivers up to 103.125 Gbps data rate, split across 4 lanes of 25.78 Gbps. It uses a duplex LC connector for simple integration into standard SMF cabling environments and supports up to 10 km (6.2 miles) of transmission distance. The transceiver uses an EML (Electro-absorption Modulated Laser) transmitter and a PIN receiver, with built-in CDR (Clock and Data Recovery) for both TX and RX paths. It includes Forward Error Correction (FEC) in compliance with KP4 standards, ensuring link integrity over longer distances.
Key Features:
-
100GBASE-LR over SMF: Supports up to 10 km at 1310 nm
-
QSFP28 Form Factor: Compact and high-density for modern data center platforms
-
Built-in CDR and FEC (KP4): Enhanced signal integrity over long distances
-
Duplex LC Connector: Standardized for easy fiber management
-
Advanced Modulation (PAM4): Delivers high throughput per channel with minimal footprint
The QSFP-100G-LR-S offers a long-range, high-reliability solution for 100G Ethernet applications across large-scale optical networks.
