What is the Cisco CW9166I-B? Industrial-Grade
Introduction to the Cisco CW9166I-B The Cisco CW9...
The Cisco ONS-QSFP28-LR4= is a 100GBase-LR4 QSFP28 transceiver designed for high-speed data transmission over single-mode fiber (SMF) in data center interconnects (DCI), enterprise backbones, and service provider networks. This hot-swappable module enables 100 Gigabit Ethernet connectivity with a reach of up to 10 kilometers, leveraging 4x25G NRZ modulation across four independent lanes. Key innovations include:
The transceiver complies with IEEE 802.3ba, QSFP28 MSA, and CPRI standards, ensuring interoperability in multi-vendor environments.
Cisco’s 2024 Optical Component Report validates the following metrics:
In lab tests, the module achieved <0.5 ns/m latency and maintained <1E-15 BER under -5°C to 75°C thermal cycling, validating its robustness in edge deployments.
A cloud provider deployed 500 transceivers in Cisco NCS 2004 platforms to link three data centers over 10 km SMF spans, achieving 400G aggregate capacity per fiber pair with CDM (Coherent Driver Modulator) technology.
A European telecom used the ONS-QSFP28-LR4= in Cisco ASR 9000 routers to transport eCPRI fronthaul traffic between Cisco Ultra M6 radios and centralized units, ensuring <100 μs latency for ultra-reliable low-latency communication (URLLC).
A Tokyo stock exchange reduced timestamp jitter to ±3 ns across Cisco Nexus 9300-FX2 switches, leveraging the transceiver’s clock recovery capabilities for high-frequency trading (HFT) applications.
The module integrates DSP-based dispersion compensation, tolerating ≤1,600 ps/nm at 1310 nm without external dispersion-compensating modules (DCMs).
Yes, but optimal performance requires Cisco NCS 2000 or Cisco ONS 15454 platforms for FEC (Forward Error Correction) and pre-emphasis adjustments.

From 30+ global installations, two lessons emerge:
While 800G technologies dominate discourse, the ONS-QSFP28-LR4= remains pivotal for enterprises balancing performance and budget. In sectors where latency and uptime equate to revenue—finance, healthcare, defense—this transceiver isn’t just a component; it’s a strategic asset. For network architects, its value lies not in GHz or Tbps, but in the silent, relentless reliability that underpins every transaction, stream, and query.
