QSFP-100GBASE-SR4-FL Juniper (100GBase-SR4) Optical Transceiver

Data Sheet:  HTML   PDF 

The QSFP-100GBASE-SR4-FL is a parallel 100 Gbps Quad Small Form-factor Pluggable (QSFP28) optical module. It provides increased port density and total system cost savings. The QSFP28 full-duplex optical module offers 4 independent transmit and receive channels, each capable of 25 Gbps operation for an aggregate data rate of 100 Gbps on 100 meters of OM4 multi-mode fiber. An optical fiber ribbon cable with an MTP/MPO connector can be plugged into the QSFP28 module receptacle. Proper alignment is ensured by the guide pins inside the receptacle. The cable usually cannot be twisted for proper channel to channel alignment. The module operates by a single +3.3V power supply. The QSFP-100GBASE-SR4-FL is designed with form factor, optical/electrical connection and digital diagnostic interface according to the QSFP28 Multi-Source Agreement (MSA). It has been designed to meet the harshest external operating conditions including temperature, humidity and EMI interference. The module offers very high functionality and feature integration, accessible via a two-wire serial interface.

FluxLight's QSFP-100GBASE-SR4-FL is a Juniper® compatible 100GBase QSFP28 Optical Transceiver and is factory pre-programmed with all the necessary configuration data for seamless network integration. Our transceivers perform identically to Juniper® original transceivers and are 100% compatible with other OEM and third party transceivers. The QSFP-100GBASE-SR4-FL is 100% MSA (Multi-Source Agreement) compliant. All FluxLight's transceivers are tested for 100% functionality and guaranteed compatible for outstanding network performance.

FluxLight offers all brands and form factors of Optical Transceivers for all your networking needs. Now you have a reliable, compatible and affordable means to expand your network while maintaining its integrity.

Product Quality

Since its inception in 2004, Fluxlight has continually refined its processes to assure the best possible quality for our customers. The foundational elements of these processes are Record-Keeping and Quality Assurance Testing (QAT). To maintain a robust data archive, each part is individually serialized both in its internal EEPROM memory and on its external label. All QAT results and other important information (e.g., manufacture date, compatibility programming) are associated with each Serial Number stored in our cloud-based secure database. QAT consists of visual part inspection as well as verification of all critical parameters and performance of each part. For the QSFP-100GBASE-SR4-FL optical output power and wavelength (850nm) are verified on optical spectrum analyzers. Receiver sensitivity is verified at both minimum distance and the 100m maximum range over actual (not simulated) MMF , multimode fiber cable. Digital Diagnostics Monitoring (DDM) parameters including: optical output power, receive optical power, internal module temperature, transmit bias current and supply voltage, are tested for compliance with specifications. In addition, the part is verified for proper operation across its full operating temperature range, 0C to 50C.


The following is a list of Finisar Corporation patents Fluxlight has licensed. This licensure recognizes and compensates Finisar for their intellectual property. The QSFP-100GBASE-SR4-FL, like all Fluxlight optical transceivers, is covered by this license agreement. Therefore, Fluxlight customers can rest assured that all products purchased are fully licensed, and our customers are under no potential liability that may ensue from the use of unlicensed optical transceiver products.
