Dell QSFP-40G-ESR4 05FVP7 AFBR-79EEPZ-FT1 40G eSR4 Extended Reach QSFP+ Multi-Mode Transceiver

Basic Parameter Table

Core Product Features

1. Dell OEM Avago 40G extended short-reach multi-mode parallel QSFP+ optical transceiver, fully compatible with Dell PowerEdge rack servers and Dell enterprise QSFP+ leaf/spine switches.
2. 850nm four parallel lane optical design compliant with 40GBASE-eSR4 standard, supporting up to 400-meter transmission via OM4 multi-mode ribbon fiber, much longer than standard 100m SR4 modules.
3. Hot-swappable QSFP+ form factor integrated with complete DDM (Digital Diagnostic Monitoring), real-time monitoring of each channel’s Tx/Rx optical power, module temperature and supply voltage.
4. Low-power industrial wide-temperature hardware design, stable 24/7 continuous operation in large-scale high-density data center rack environments.
5. Native 4×10G parallel architecture, compatible with MPO-to-LC breakout cables to split into four independent 10G SR links for flexible server access layout.
6. Extended reach advantage: covers medium-distance same-building fiber layout without single-mode cabling, effectively reducing cabling cost for mid-range interconnections.

Application Scenarios

1. Medium-distance intra-data center rack 40G interconnection, leaf-spine core switch uplink, storage cluster networking within 400 meters using OM4 ribbon fiber.
2. Multi-row cabinet cluster interconnection, breakout 4×10G links for mass compute node access via ribbon fiber trunk.
3. Not suitable for cross-building long-distance single-mode transmission and CAT copper wiring scenarios.
