Specifications

Description:

Cisco QSFP-40G-CSR4 is a QSFP+ (Quad Small Form-factor Pluggable Plus) optical transceiver designed for 40G Ethernet connectivity over multimode fiber (MMF). Using four parallel 10Gbps lanes, it supports extended short-reach distances and provides an affordable, scalable, and high-speed solution for high-density data environments like enterprise data centers and campus networks.

Features & Specifications:

Part Number: QSFP-40G-CSR4
Form Factor: QSFP+ (40GBASE-CSR4)
Data Rate: 40 Gbps (4 x 10Gbps lanes)
Wavelength: 850 nm
Cable Type: Multi-Mode Fiber (MMF)
Connector Type: MPO-12, 4 parallel fiber lanes
Transmission Distance: 300m over OM3, 400m over OM4
Digital Diagnostic Monitoring (DDM): Yes (for real-time performance metrics)
Power Supply: 3.3V typical
Hot-Pluggable: Yes
Compliant Standards: IEEE 802.3ba 40GBASE-CSR4, MSA Compliant, RoHS

Ideal Use Cases:

Enterprise Data Centers: Optimized for high-speed, short-to-medium distance server-to-switch or switch-to-switch connections.
Campus Networks: Ideal for connecting IDFs (Intermediate Distribution Frames) across larger campus floors using OM3/OM4 cabling.
Aggregation and Core Layers: Efficient uplinks from access layer switches to core switches.
Modular Switch Environments: Fits into QSFP+ slots in modular switch blades or line cards.

Why Choose the QSFP-40G-CSR4?

Extended Short Range: Goes beyond standard SR4 (Short Range) with up to 400m on OM4 fiber — ideal for medium-reach applications without requiring SMF.
High Bandwidth: Delivers full-duplex 40Gbps throughput for bandwidth-intensive data center traffic.
Interoperability: Fully compatible with a wide range of vendors and platforms following MSA standards.
Scalability: Ideal for modernizing networks toward higher bandwidth while preserving investment in MMF cabling.
Efficient Deployment: MPO interface enables fast, clean, and high-density installations.
