100G QSFP28 is a high-speed pluggable optical module, supporting 4*25 NRZ mode transmission, each independent channel rate up to 25.78Gbps. according to the fiber type can be divided into single-mode and multi-mode. According to the interface type can be divided into single-fiber bidirectional and dual-fiber bidirectional two.
FAQ About 100G Optical Transceivers
QSFP28 100G transceivers offer four 25 Gbps lanes in a single compact form factor, delivering 100 Gbps throughput with minimal power consumption. Their high port density and support for standards like 100GBASE-SR4 and 100GBASE-LR4 simplify network upgrades in hyperscale environments.
When choosing 100G optical transceivers, compare module types—SR4 for multimode short‑reach (up to 100 m), LR4 for single‑mode long‑reach (up to 10 km), and CWDM4 for cost‑effective 2 km links. Always verify compatibility with your fiber infrastructure and switch vendor’s interoperability list.
A dependable 100G transceivers supplier maintains ISO 9001 certification, operates in‑house BER and DDM test labs, and provides published compatibility matrices for OEM brands like Cisco, Juniper, and Arista. (eg.Fibrecross)
Ordering wholesale 100G transceivers typically unlocks bulk‑order discounts of 20–40% off list prices. Key factors include minimum order quantities (MOQs), warranty terms, module types (SR, LR, ER), and shipping lead times—especially important for large campus or hyperscale rollouts.
Most modern switches with QSFP28 cages support break‑out configurations, allowing 100G transceivers to split into four 25 Gbps channels compatible with SFP28 ports.
