The module is aimed at data center engineers and network operators who need a straightforward, MSA-compliant 100GbE QSFP28 option compatible with Dell QSFP28-100G-SR4 ports. The single biggest reason to consider this module is dependable short-range 100G connectivity up to 70 m on OM3 and 100 m on OM4 with hot-pluggable convenience and built-in DDM for link diagnostics, making it a practical replacement or spare for fiber switches, NICs and servers.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eCompatibility:\u003c\/strong\u003e Works with Dell QSFP28-100G-SR4 ports and other MSA-compliant devices to simplify deployment in mixed environments.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e100Gb\/s performance:\u003c\/strong\u003e QSFP28 form factor supports full 100G Ethernet throughput for high-bandwidth aggregation and server uplinks.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMultimode reach:\u003c\/strong\u003e 850nm optics deliver up to 70 m on OM3 and up to 100 m on OM4, covering most rack-to-rack and short spine links.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eMonitoring:\u003c\/strong\u003e Built-in DDM (DOM) provides real-time diagnostic information so administrators can spot transceiver issues quickly.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eEase of use:\u003c\/strong\u003e Hot-pluggable, plug-and-play operation allows fast replacements or additions without service interruptions.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eQuality control:\u003c\/strong\u003e Each module is individually tested on switches prior to shipping, reducing the chance of DOA failures.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eWho It's For\u003c\/h2\u003e\u003cp\u003eThis module is best suited for data center operators, network engineers and system integrators who require 100GbE short-reach links between switches, top-of-rack devices and high-speed servers.
