Questions & Answers
What is a 4-channel EWDM OADM module?
A 4-channel EWDM OADM module is a passive optical add-drop multiplexer that supports four discrete Enhanced Wavelength Division Multiplexing channels, enabling precise insertion and extraction of specific wavelengths for scalable, high-performance fiber-optic networks.
What are the key features of the EWDM-OADM4?
The EWDM-OADM4 offers low insertion loss (≤1.7 dB), high isolation (>40 dB), support for four EWDM wavelengths, wide operating temperature (–40 °C to +85 °C), and standard LC/UPC connectors for reliable metro and access deployments.
How does the EWDM-OADM4 improve network performance?
By selectively adding and dropping four wavelengths, the EWDM-OADM4 reduces channel congestion, optimizes bandwidth, and minimizes signal degradation, resulting in higher throughput, lower latency, and simplified network expansion.
What is the insertion loss per channel on the EWDM-OADM4?
The typical insertion loss is ≤1.7 dB per channel, ensuring minimal signal attenuation and consistent optical performance in high-density multiplexing scenarios.
Which wavelength grid does the EWDM-OADM4 use?
The module conforms to the ITU-T G.694.1 DWDM grid with 100 GHz (≈0.8 nm) channel spacing, allowing flexible selection of four wavelengths within the C-band for precise network design.
What fiber type is compatible with the EWDM-OADM4?
The EWDM-OADM4 is fully compatible with standard single-mode fiber (SMF-28), enabling seamless integration into existing fiber-optic infrastructures without special cabling.
What is the operating temperature range of the EWDM-OADM4?
The module operates reliably from –40 °C to +85 °C, making it suitable for both indoor and harsh outdoor environments with wide temperature fluctuations.
How do I install the 4-channel EWDM OADM module?
Installation is plug-and-play: connect the input, pass-through, add, and drop ports via LC/UPC connectors into your OLT, ROADM, or FTTx chassis—no special tools or calibration required.
Can the EWDM-OADM4 be customized for different wavelengths?
Yes. You can request customized channel assignments on the EWDM-OADM4 to match specific network plans, with tailored wavelength sets up to four channels per module.
Which connectors are supported by the EWDM-OADM4?
Standard duplex LC/UPC connectors are provided by default. Optional connector types, including SC/UPC or other polished ceramic interfaces, are available upon request.
What applications is the EWDM-OADM4 ideal for?
The module is ideal for metro, access, FTTx, and campus networks, enabling cost-effective wavelength add/drop in high-density EWDM systems and supporting future capacity growth.
How does the EWDM-OADM4 ensure low crosstalk?
High channel isolation (>40 dB) and low adjacent-channel crosstalk (<25 dB) are achieved through precision-engineered AWG filters, preserving signal integrity across all four wavelengths.
Can I scale beyond four channels with the EWDM-OADM4?
Yes. By cascading multiple EWDM-OADM4 modules, you can build larger EWDM networks supporting dozens of wavelengths while maintaining low loss and high isolation.
How do I maintain and clean the EWDM-OADM4?
Perform routine connector cleaning with isopropyl alcohol and lint-free wipes, inspect for dust, and reseal protective caps. No internal realignment or calibration is required.
What warranty and support are offered for the EWDM-OADM4?
The module comes with a one-year standard warranty, extendable up to three years. Lifetime technical support, rapid RMA handling, and optional on-site services ensure uninterrupted operation.
Where can I purchase the EWDM-OADM4 module?
You can buy the EWDM-OADM4 from authorized distributors, online resellers, or directly through our sales team. Visit our website or contact sales@example.com for pricing and availability.
