Frequently Asked Questions
The operating wavelength for the circulator is from 1290 nm to 1620 nm.
The transmitting direction for the 3-port circulator is from port 1 to port 2, and from port 2 to port 3.
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.
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.
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.
The maximum PMD is 0.2 ps. This is a measure of the differential delay of various polarization modes in a fiber.
The minimum Return Loss is 50 dB. This is a measure of the power reflected back to the source.
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.
The maximum Optical Power Handling is 300 mW. This is the maximum level of light power that the circulator can handle without being damaged.
The operating temperature range is from -5 to 70 degrees Celsius, and the storage temperature range is from -40 to 85 degrees Celsius.
The standard package dimensions are Φ5.5 x L50 mm, and the mini package dimensions are Φ5.5 x L38 mm.
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.
