QSFP-100G-SL4-RF

100GBASE SL4 for up to 30M over OM4 MMF REMANUFACTURED

The QSFP-100G-SL4-RF is a professionally remanufactured Cisco 100GBASE-SL4 Short Link QSFP28 Transceiver, designed as a cost-optimized short-reach alternative to QSFP-100G-SR4-S for in-row data center 100G connectivity. The QSFP-100G-SL4 transmits at 850 nm over four-lane parallel multimode fiber, supporting up to 20 m over OM3 and 30 m over OM4 with an MPO-12 connector, and is interoperable with 25G SFP+ optics in 4x25G breakout mode.

This remanufactured transceiver has been professionally inspected, tested, and restored to meet Cisco's quality standards. Each unit undergoes verification of transmit optical power and receive sensitivity across all four 25G lanes, validation of EEPROM signaling and digital optical monitoring, and physical inspection of the MPO-12 optical interface.

Key Features:
• 100 Gigabit Ethernet short-reach QSFP28 transceiver over four-lane parallel MMF
• 850 nm transmit wavelength with four 25G VCSEL lanes for aggregate 100G throughput
• Up to 20 m reach on OM3 and 30 m reach on OM4 multimode fiber via MPO-12 connector
• Interoperable with QSFP-100G-SR4-S and supports 4x25G SFP28 breakout mode
• Digital Optical Monitoring (DOM) for per-lane live diagnostics and signal telemetry
• Cost-optimized alternative to SR4-S for short in-row data center 100G interconnects
