CWDM‑OADM4‑2 Specifications

Cisco 4‑Channel CWDM Optical Add/Drop Multiplexer Module

Manufacturer: Cisco
Manufacturer Model: CWDM‑OADM4‑2
Product Line: Cisco CWDM Passive Optical System
Product Series: 4‑Channel OADM (Add/Drop)
Product Type: Passive Optical Add/Drop Module
Product Name: Cisco 4‑Channel CWDM OADM Module (1550–1610 nm)

KEY FEATURES:

4 add/drop channels: 1550 nm, 1570 nm, 1590 nm, 1610 nm

Transparent for legacy wavelengths; includes filter to mix with 1300 nm signals (e.g., SONET/SDH)

Dual-fiber design: separate fibers for “east” and “west” direction connections

Monitor port: Allows connection of an optical power meter or optical spectrum analyzer for performance monitoring

PERFORMANCE:

Insertion Loss (Add/Drop): Typically low, as per CWDM passive system specification

Pass‑through Loss: Other CWDM wavelengths pass through with minimal loss

Isolation: High isolation between add/drop wavelengths to minimize cross-talk

ENVIRONMENTAL & RELIABILITY:

Operating Temperature: As per Cisco’s passive optical system guidelines

Passive device: Requires no power; long operational life typical in passive WDM systems

End‑of‑Life / Support: Last support date is August 31, 2029

PHYSICAL:

Form Factor: Module designed for CWDM 2‑slot chassis (e.g., CWDM‑CHASSIS‑2)

Typical Size: Same physical size as other OADM modules in Cisco’s CWDM system

COMPATIBILITY & NOTES:

Compatible Chassis: Requires Cisco CWDM 2‑slot passive chassis

Use Case: Ideal for metropolitan or campus optical rings where specific CWDM wavelengths need to be added/dropped at certain nodes

Port Matching: Use CWDM SFP/GBIC modules matching the add/drop wavelengths (1550/1570/1590/1610 nm)

Monitoring: Recommended to use the monitor port for optical power verification or spectrum analysis during commissioning and maintenance
