Questions & Answers
What is the CWDM-OADM1-1490 Dual Single Channel OADM Module?
The CWDM-OADM1-1490 is a passive optical add/drop multiplexer that inserts and extracts only the 1490 nm CWDM channel on a single-mode fiber link, enabling cost-efficient wavelength management.
What applications is the 1490 nm OADM module suitable for?
This module is ideal for metro, access, FTTH and campus networks where a single 1490 nm data or video channel must be added or dropped without disrupting other CWDM wavelengths.
How does the 1490 nm channel function in this dual single channel OADM?
It demultiplexes upstream 1490 nm traffic from the CWDM trunk to a local drop port and multiplexes local 1490 nm signals back onto the trunk, isolating other CWDM channels.
What are the key specifications (insertion loss and isolation) of this module?
Typical insertion loss is ≤1.0 dB; channel isolation is ≥30 dB; and adjacent-channel crosstalk is ≤–25 dB, ensuring high signal integrity.
Which fiber type and connector interfaces are supported?
The module uses ITU-T G.652 single-mode fiber and LC/UPC connectors on all ports for low‐loss, high‐reliability connections.
Is the CWDM-OADM1-1490 compliant with ITU-T G.694.2 standards?
Yes, it fully complies with ITU-T G.694.2 CWDM wavelength grid, guaranteeing seamless integration with standardized CWDM systems.
What operating temperature and environmental range does it support?
Operating range is –40 °C to +85 °C with humidity tolerance up to 95% non-condensing, suitable for indoor and network-edge deployments.
How do I install the CWDM-OADM1-1490 in a patch panel?
Slide the module into a compatible 1U/2U 19″ chassis slot, secure it with mounting screws, and connect trunk and drop fibers to the labeled ports.
Can this module be used for bi-directional CWDM transmission?
Yes, it supports bi-directional operation on the 1490 nm channel, allowing upstream and downstream traffic over the same fiber pair.
How is the return loss performance of this OADM at 1490 nm?
Return loss is ≥45 dB on all ports at 1490 nm, minimizing back-reflection and preserving transmitter stability.
What maintenance and cleaning procedures are recommended?
Use dry-type optical cleaning tools for LC/UPC connectors, inspect with a fiber microscope, and keep dust caps on unused ports when idle.
What packaging and mounting options are available?
Available as a plug-in module for 1U or 2U 19″ rack chassis or as a standalone inline assembly with protective housing.
What is the typical lead time and shipping process?
Standard lead time is 1–2 weeks; expedited options are available. Shipments include anti-static packaging and tracked courier delivery.
What warranty and after-sales support are provided?
Comes with a 3-year manufacturer’s warranty, lifetime technical support and access to firmware updates, if applicable.
How does the CWDM-OADM1-1490 compare to other CWDM OADM solutions?
It offers lower insertion loss, higher channel isolation and broader temperature tolerance than generic OADMs, making it ideal for mission-critical CWDM networks.
