Cisco QSFP-100G-SR4-S Compatible 100G QSFP28 SR4 Optical Transceiver Module | HYTOPTODEVICE

The QSFP-100G-SR4-S is the workhorse of Cisco's 100G optical portfolio. As part of the "S-Class" family, it is specifically optimized for standard 100G Ethernet applications in data centers and enterprise cores, focusing on the most common features for maximum reliability.with full DDM/DOM monitoring support.

This module transmits at 850nm over multi-mode fiber (MMF), supporting link lengths up to 100m on OM4 (70m on OM3) via an MPO-12 connector. With a commercial-grade operating temperature of 0°C to 70°C, it is designed to handle the high-density cooling requirements of modern switch fabrics.

At HYTOPTODEVICE, our Cisco compatible modules are 100% logic-tested on original Cisco hardware. Pre-programmed with Cisco-specific EEPROM signatures, these transceivers offer "Plug-and-Play" deployment in Cisco NX-OS and IOS-XE without requiring the "unsupported-transceiver" command.

Our Cisco 100G SR4 compatible  module is verified and 100% compatible with Cisco’s leading platforms, including:

• Nexus 9000 Series: 9300, 9500 (e.g., N9K-C93180YC-FX, N9K-C9336C-FX2).

• Nexus 3000 Series: 3100, 3200 (e.g., N3K-C31108PC-V).

• Catalyst Series: Catalyst 9500, 9600, 9800-CL.

• ASR 9000 Series Routers: With compatible 100G line cards.

• Cisco UCS: 6454/64108 Fabric Interconnects.
  
  

• Data Center Spine-Leaf: Connecting Cisco Nexus 9000 series spine and leaf switches.

• Enterprise Core & Distribution: High-speed uplinks for Cisco Catalyst 9500/9600 series switches.

• 4x25G Breakout: Breaking a single 100G port into four 25G SFP28 links for server-to-switch connectivity (using MPO-to-8LC cables).

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)  to transmit distance up to 100m  through four parallel fibers at 850nm wavelength. 

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 Cisco 100G SR4?A:The 100G SR4 module uses MPO-12 connector with MMF.

Q4:Does this 100G SR4 module support DOM?A: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 technical differences between 100G SR4 vs 10G SR? A: The difference as follow:

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

 Q9:What is the difference between QSFP-100G-SR4-S vs SR4?The difference see below:

Q10:Is 100GBASE-SR4 850nm 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.
