Data Sheet CWDM Filter Chips Bookham coarse WDM filters leverage the proprietary Advanced Energetic Deposition (AED) process to produce the industry’s best filter solutions. The AED process features stateof-the-art layer thickness control to produce thin-film interference filters for optical add/drop multiplexing (OADM) WDM applications and Mux/Demux. Bookham offers a range of filtering solutions for CWDM channel spacing. Filter designs can be optimized for transmission and reflection loss for mux/demux applications or for wider wavelength coverage. Features: • O-band to L-band center wavelengths • Accurate wavelength centering • Deep reflection isolation • High adjacent channel transmission isolation • Flat transmission passband for cascading • Excellent temperature stability Options: • Extended reflection • Custom specifications Applications: • Mux/Demux Compliance: • GR-1221 qualified • RoHS compliant 1 Data Sheet CWDM Filters: Typical design specifications (valid over operating temperature) Parameter Standard Spec 0240/0241 Center Wavelength (λC) Extended Reflection Spec 0599/0600 1470, 1490, 1510, 1530, 1550, 1570, 1590, 1610 1471, 1491, 1511, 1531, 1551, 1571, 1591, 1611 (for other wavelengths, contact us) λCTolerance λC ±0.4 N/A Transmission Bandwidth -0.2dB λC ± 8 nm nm min nm λC ± 7.5 Transmission Bandwidth -0.3dB λC ± 11.5 λC ± 12.5 max nm Passband Loss Variation 0.2 0.3 max dB Passband Loss Maximum 0.4 0.35 dB Reflection Isolation 15 15.5 dB PDL, Passband & Adj.
