QSFP-40G-CSR4-RF

QSFP 4x10GBASE-SR TransceiverModule,MPO, 300M REMANUFACTURED

QSFP-40G-CSR4-RF is a professionally remanufactured Cisco 40GBASE-CSR4 QSFP+ transceiver module, designed to deliver high-speed 40 Gigabit Ethernet connectivity over multimode fiber in data center and enterprise core network environments. The module uses a parallel 4-lane architecture over MTP/MPO ribbon fiber, supporting link distances up to 400 meters on OM4 multimode fiber and up to 300 meters on OM3.

This remanufactured QSFP+ transceiver meets Cisco performance specifications and has been thoroughly inspected and tested to ensure full operational reliability. Validation includes optical transmit and receive power levels, lane-by-lane signal integrity across all four channels, and DOM (Digital Optical Monitoring) functionality for real-time diagnostics.

Key Features:
• 40GBASE-CSR4 standard supporting 40 Gbps aggregate throughput via 4x10G parallel lanes
• MTP/MPO-12 fiber connector interface for parallel multimode fiber ribbon cable
• Up to 400 meters reach on OM4 multimode fiber; up to 300 meters on OM3
• 850nm VCSEL-based optical transmitter for cost-effective multimode operation
• Digital Optical Monitoring (DOM) support for real-time power and temperature diagnostics
• Compatible with Cisco Nexus, Catalyst, and ASR platforms supporting QSFP+ form factor
