Frequently Asked Questions (FAQ)
Q What is the operating wavelength range of the COMOB filters?
The COMOB filters support a wide operating wavelength range of 1260.0 nm to 1650.0 nm, conforming to the telecommunication standards set by the International Telecommunication Union (ITU).
Q What options are available for the Passband and Reflect. Band?
We offer multiple configurations including passbands of 1550-1600 nm, 1470-1600 nm, 1290-1590 nm, and 1260-1280 nm, paired with corresponding reflection bands to suit different system requirements.
Q How stable are these filters under temperature changes?
The COMOB filters exhibit excellent thermal stability with a thermal drift (λ Thermal Drift △λ/△T) of less than 2 pm/°C across an operating temperature range of -40°C to +85°C.
Q What are the dimensions and coating specifications?
The standard dimensions are 1.4(±0.05) × 1.4(±0.05) × 0.3(±0.05) mm. They feature a high-quality backside AR coating with a reflectivity of 0.2%.
Q Can I request a custom specification not listed in the stock table?
