Frequently Asked Questions

What is the operating wavelength of the Circulator?
The operating wavelength for the circulator is from 1290 nm to 1620 nm.
What is the Transmitting Direction?
The transmitting direction for the 3-port circulator is from port 1 to port 2, and from port 2 to port 3.
What are the Isolation values?
The typical Isolation at 23℃ (room temperature) is 23 dB, and the minimum is 20 dB. Isolation is a measure of how well the circulator prevents light from traveling in the opposite direction.
What are the Insertion Loss values?
The typical Insertion Loss at 23℃ is 1.7 dB, and the maximum is 2.0 dB. Insertion Loss is the measure of the power loss when light is transmitted through the circulator.
What is the PDL (Polarization Dependent Loss)?
The maximum PDL is 0.25 dB. This is a measure of the difference in transmission loss when the optical signal's polarization states change.
What is the PMD (Polarization Mode Dispersion)?
The maximum PMD is 0.2 ps. This is a measure of the differential delay of various polarization modes in a fiber.
What is the Return Loss?
The minimum Return Loss is 50 dB. This is a measure of the power reflected back to the source.
What is the Directivity of the Circulator?
The minimum Directivity is 50 dB. Directivity is a measure of how well the circulator guides light from one port to the next without any leakage to the other ports.
What is the maximum Optical Power Handling?
The maximum Optical Power Handling is 300 mW. This is the maximum level of light power that the circulator can handle without being damaged.
What are the operating and storage temperatures?
The operating temperature range is from -5 to 70 degrees Celsius, and the storage temperature range is from -40 to 85 degrees Celsius.
What are the package dimensions?
The standard package dimensions are Φ5.5 x L50 mm, and the mini package dimensions are Φ5.5 x L38 mm.
What is the fiber type, fiber length, and connector type?
The fiber type can be SMF-28 with either 250um or 900um. The fiber length can be customized from 1.0m to 3.0m. The connector type can be none (NE), FC/APC (FA), FC/PC (FC), SC/APC (SA), SC/PC (SC), ST/PC (ST), LC/APC (LA), or LC/PC (LC). Different options or configurations can be requested from Ascentta.
