The GigaTech Products 100GBase QSFP28 SR BiDi is a parallel Quad Small Form-factor Pluggable that supports 100 Gbps bit rates. It integrates four host electrical data into two optical lanes using a 2-fiber duplex LC optical multi-mode fiber. Operating with 50Gb PAM4 channels, the module achieves a total aggregate bandwidth of 100Gb, enabling efficient data transfer at 50Gb with 25Gbaud signaling rates. On the receiver side, it de-multiplexes two sets of optical input signals, converting them into four channels of electrical data. Users can easily connect the module with an optical fiber ribbon cable featuring an LC connector.

Never Sourced. Never Recycled.

All components in GigaTech Product optics are manufactured under the same roof and represent the gold standard for reliability and consistency in performance. This vertical manufacture chain allows GigaTech to avoid unnecessary variances in transceiver casing or laser quality often found with online resellers who source their components from an ever changing vendor list. The transceiver is guaranteed to be built from A-Stock never used components overseen by GigaTech Products,

Rigorous Testing & Standards Compliance

The quality and standards of our hardware is one the base foundations of GigaTech Products. All of our components comply with MSA (Multi-Source Agreement) output standards and, in many cases, excel beyond those certification standards. Every transceiver we produce is tested on active network devices to ensure they comply with OEM equipment and are verified to be plug-and-play and do not require work arounds.
