1. Overview of Aruba 3810M Switch Series

Aruba 3810M series is mainstream enterprise Layer 3 stacking switch with modular 10G SFP+ and 40G QSFP+ uplink slots, widely used in campus, SMB and branch office networks. This article fully sorts ETU-LINK matching optical modules, DAC twinax cables, fiber patch cords and deployment schemes for Aruba 3810M including JL075A model, with complete distance and hardware reference for network engineers.

The Aruba 3810 Switch Series provides performance and resiliency for enterprises, SMBs and branch office networks. With HPE Smart Rate multi-gigabit ports for high speed access points and IoT devices, this advanced Layer 3 network switch delivers a better application experience with low latency, virtualization with resilient stacking technology, and line rate 40GbE for plenty of back haul capacity.

Core Hardware Key Features

u Advanced Layer 3 switch series with backplane stacking, low latency and resiliency

u Security and network management tools with ClearPass Policy Manager, AirWave and Central support

u Modular line rate 10GbE and 40GbE ports for wireless aggregation

u HPE Smart Rate for high-speed multi-gigabit capacity and PoE+ power

Optimized for innovative SDN applications with OpenFlow support

All 3810M uplink expansion slots support mixed deployment of 10G SFP+ and 40G QSFP+ modules, supporting breakout mode for QSFP+ to four 10G SFP+ to realize mixed 10G/40G network upgrade without replacing whole switches.

2. Full List of ETU-LINK Optical Modules Compatible with

Optical module for Aruba 3810M switch:

All above transceivers pass real machine aging test on full 3810M models, fully comply SFP/QSFP MSA and SFF-8472 DDM standards. Switches can normally read Tx/Rx optical power, temperature, laser bias current without compatibility alarm, supporting bidirectional BiDi single-fiber modules to save fiber core resources for campus building interconnection.

4. Supporting Fiber Patch Cord Matching Scheme

Aruba 3810M switch optical module application:

Fiber matching rules:
1) 850nm multimode SFP/SFP+/40G SR4: OM3 / OM4 duplex LC / MPO patch cord
2) 1310/1550nm single-mode LR/ER/ZR modules: OS2 low-loss single-mode duplex LC patch cord
3) 40G LR4 QSFP+ uses dual LC four-channel parallel single-mode fiber to realize 10km long-distance core uplink.
