Cisco QSFP+ Module – Single-mode – 16 Gigabit Ethernet – Fiber Channel, 16GBase-SW
Cisco ONS-QC-16GFC-LW=
4×16G Fibre Channel QSFP+ Module
A single-mode, long-wavelength QSFP+ transceiver that packs four independent 16G/8G Fibre Channel lanes into one hot-pluggable module — built for long-haul SAN extension over Cisco NCS 2000-series optical platforms.
Overview
The ONS-QC-16GFC-LW= is a Cisco QSFP+ pluggable built specifically for optical transport of Fibre Channel SAN traffic. Rather than one high-speed lane, it carries four independent 16G (or 8G, auto-negotiated) Fibre Channel channels over a single long-wavelength, single-mode fiber pair — making it a common choice on Cisco NCS 2000 muxponder and transponder line cards for data-center-interconnect and SAN extension deployments.
4-lane FC aggregation
Four independent 16G/8G Fibre Channel channels multiplexed through one QSFP+ cage — fewer slots, fewer cables.
Long-wave single-mode
1310 nm long-wavelength optics on single-mode fiber for extended reach between SAN sites and data centers.
MSA-compliant, hot-swappable
Standard QSFP+ mechanical and electrical interface (SFF-8636) for tool-free insertion and removal.
Built-in diagnostics
Digital Optical Monitoring reports real-time temperature, voltage, bias current, and per-lane optical power.
