Cisco CWDM-MUX-4-SF1 4-Channel Single-Fiber CWDM Multiplexer/Demultiplexer – Passive Optical MUX/DEMUX

The Cisco CWDM-MUX-4-SF1 is a passive 4-channel Coarse Wavelength Division Multiplexing (CWDM) multiplexer/demultiplexer designed to transport four separate optical channels over a single strand of single-mode fiber. It is part of Cisco's CWDM passive optical system and is designed for point-to-point single-fiber applications.

The module uses different CWDM wavelengths to combine four optical services onto one fiber strand. Cisco specifies that the CWDM-MUX-4-SF1 and CWDM-MUX-4-SF2 must be used together to create the complete four-channel single-fiber point-to-point link. Dual fiber is used for the connections to the compatible CWDM transceivers, while a single fiber is used for the network connection.

• Designed for four separate optical channels
• Must be paired with CWDM-MUX-4-SF2 for the complete single-fiber link
• Uses wavelength-division multiplexing to increase fiber capacity
• Dual-fiber connections toward compatible CWDM transceivers
• Passive optical operation with no electrical power requirement
• Designed for compatible Cisco CWDM optical systems

Cisco CWDM-MUX-4-SF1 Technical Specifications

Single-Fiber 4-Channel CWDM Operation

The CWDM-MUX-4-SF1 combines four individual optical channels into a single fiber strand. Each service uses a different CWDM wavelength, allowing multiple optical connections to share the same physical fiber.

At the receiving end, the corresponding demultiplexer separates the individual wavelengths back into their respective optical channels. This architecture increases the capacity of an existing single-fiber infrastructure without requiring additional fiber strands.

CWDM-MUX-4-SF1 and CWDM-MUX-4-SF2 Pairing

The CWDM-MUX-4-SF1 is not designed to operate as a standalone end-to-end single-fiber system. Cisco specifies that the SF1 and SF2 modules must be used together to create the four-channel single-fiber point-to-point link.

The two modules use complementary CWDM wavelength groups so that four bidirectional optical services can share one fiber strand.

Passive Optical Architecture

The CWDM-MUX-4-SF1 is a passive optical component. It does not contain an Ethernet transmitter, receiver or electrical signal-processing engine and does not require external electrical power. The active optical transmission is provided by compatible Cisco CWDM transceivers connected to the equipment-side ports.

CWDM Transceiver Compatibility

The module is designed to operate with compatible Cisco CWDM optical transceivers. The transceiver wavelength must correspond to the appropriate CWDM channel of the MUX/DEMUX system.

Before deployment, verify the exact Cisco CWDM transceiver, chassis, connector and wavelength requirements for the intended network configuration.

Applications

• Single-fiber CWDM point-to-point links
• Enterprise optical networks
• Metropolitan-area networks (MAN)
• Campus network interconnection
• Data center interconnects
• Carrier and service-provider networks
• Fiber capacity expansion where only one fiber strand is available
• Multi-service optical transport

Compatibility

The Cisco CWDM-MUX-4-SF1 is part of the Cisco CWDM passive optical system and should be deployed with its required companion CWDM-MUX-4-SF2. Cisco documentation distinguishes these single-fiber modules from conventional dual-fiber CWDM MUX/DEMUX and OADM modules.

The module can be installed in compatible Cisco CWDM chassis infrastructure. Confirm the exact chassis and optical transceiver compatibility before purchase.

Important: MUX/DEMUX, Not an OADM Transceiver

Although this SKU may be listed by some sellers as a “Transceiver OADM Module,” the CWDM-MUX-4-SF1 is technically a passive 4-channel MUX/DEMUX. Cisco's product documentation explicitly describes it as a Single Fiber 4-Channel Mux/Demux, while Cisco identifies its OADM products separately.

End-of-Sale Information

Cisco has announced the CWDM-MUX-4-SF1= as an end-of-sale product. Cisco's lifecycle announcement identifies it as a Single Fiber 4-Channel Mux/Demux and states that there is currently no replacement available.
