Abstract
A pluggable optical protection switch (OPS, 103) is able to select between two fiber lines (109, 111) wherein a selected fiber line is an active fiber line and an unselected fiber line is a redundant standby fiber line. The pluggable OPS may be designed in a Quad Small Factor Pluggable (QSFP) form factor, such as a QSFP-DD form factor or a QSFP28 form factor.
Claims15
A system, comprising:
- a small form-factor pluggable (SFP) device comprising:
