HPE Aruba JL309A Compatible 100G QSFP28 SR4 Optical Transceiver Module | HYTOPTODEVICE

The JL309A (Aruba X151) compatible transceiver is a short-reach 100Gbps QSFP28 module， designed for high-bandwidth campus and data center networks. Utilizing 850nm VCSEL technology, it provides reliable data transmission over multi-mode fiber (MMF).

This QSFP28-100G-SR4 Aruba module supports a reach of up to 100m over OM4  (70m over OM3) using an MPO-12 connector. It is engineered for stability in high-density environments, featuring a commercial-grade operating temperature of 0°C to 70°C.

At HYTOPTODEVICE, our JL309A compatible modules are 100% logic-tested on original Aruba hardware. Pre-programmed with Aruba-specific EEPROM signatures, they ensure seamless "Plug-and-Play" integration into AOS-CX and ArubaOS-Switch systems with full DDM/DOM monitoring support.

Our Aruba JL309A compatible module is verified and 100% compatible with Aruba Networking platforms, including:

• Aruba 83xx Series: 8320, 8325, 8360.

• Aruba 8400 Series Core Switches.

• Aruba 6300 / 6400 Series (AOS-CX).

• Aruba 5400R zl2 (with 100G modules).
  
  

• Campus Core Aggregation: Short-range 100G links between Aruba 8320/8325/8400 core switches.

• Data Center Leaf-Spine: High-speed interconnects for Aruba AOS-CX based leaf-spine architectures.

FAQ for 100G  QSFP28 SR4 Optical Module

Q1:What is QSFP28 100G SR4 module? A:The 100G SR4 is a hot pluggable optical transceiver module.It is typically built in a QSFP28 form factor, uses a multimode fiber (MMF) and is transmitted through four parallel fibers at 850nm wavelength. It is ideal for 100G Ethernet links, Infiniband QDR and DDR interconnects, Data center and Enterprise networking.

Q2:Is 100m over OM4 Possible with 100G QSFP28 SR4 optical module?A:HYTOPTODEVICE QSFP28 100G SR4 module supports the maxium transmitting distance of up to 100m.

Q3:What fiber connector is required for the Aruba 100G SR4?A:The 100G SR4 module uses MPO-12 connector with MMF.

Q4:Does this 100G SR4 module support DOM?A:Yes. Yes, it supports Digital Optical Monitoring (DOM) for real-time monitoring, allowing monitoring of optical power,laser bias current,temperature and voltage.

Q5:What does "SR4" stand for in 100G SR4?A: SR4 stands for "Short Distance 4-Channel". It uses four parallel fibers at 850nm wavelength to transmit 100G traffic over MMF up to 100m.

Q6:How can I use this for 100G to 4x25G breakout?A: Our 100G QSFP28 SR4 modules supports breakout mode, you can us MTP to 8LC cables to connect them.

Q7:Q: What are the key differences between 100G SR4 vs 10G SR? A: The difference as follow:

Q8:Is the 100G QSFP28 SR4 connected with SFP+10G?A: NO.A 100G QSFP28 SR4 and a 10G SFP+ SR is not connnected.  They mismatch in data rates, lane configuration, and physical signaling.

 Q9:What is the difference between Aruba JL309A and JL310A?The difference see below:

Q10:Is 100GBASE-SR4 module hot pluggable?A:Yes,HYTOPTODEVICE 100g optical modules are hot-pluggable, hot Pluggable QSFP28 MSA Compliant.you can plug or unplug the optical module, while the device is powered on without damaging the hardware.
