About CWDM Technology: Coarse Wavelength Division Multiplexing uses 20nm channel spacing to multiplex four wavelengths (1271/1291/1311/1331nm) over a single fiber pair. This approach delivers cost-effective 100 Gigabit transmission without the temperature-controlled lasers required by DWDM systems.

Why Extended 10km Reach Matters
Standard SR4 modules limit transmission to 100 meters over multimode fiber. This single-mode fiber transceiver extends connectivity by 100x, enabling deployment scenarios that short-range optics cannot address:
Metro Data Center Interconnect: Connect geographically distributed facilities across a metropolitan area without signal regeneration.
Campus Network Backbone: Link buildings across corporate, university, or hospital campuses with high-bandwidth connectivity.
Disaster Recovery Links: Establish synchronous replication to DR sites located kilometers from primary data centers.
Existing Fiber Utilization: Leverage installed single-mode infrastructure originally deployed for longer-distance applications.
Typical Deployment Environments
This long-reach CWDM optical transceiver serves organizations requiring high-bandwidth connectivity beyond the 100-meter limitation of multimode solutions. Service providers building metro Ethernet networks deploy these modules to deliver enterprise services across city-wide footprints. Large enterprises with distributed campus environments use them for backbone connectivity between headquarters, branch buildings, and remote data centers. Healthcare systems and universities with facilities spread across multiple city blocks rely on this solution to consolidate traffic into centralized infrastructure. Colocation providers leverage CWDM wavelength multiplexing to maximize fiber utilization when interconnecting adjacent facilities.

Frequently Asked Questions
Q: Can this module work in a CWDM4 multiplexed configuration?
A: Yes. The 1290nm wavelength is one of four channels (1271/1291/1311/1331nm) in the CWDM4 scheme. When combined with complementary wavelength modules and a passive CWDM multiplexer, you can aggregate 100 Gigabit traffic over a single fiber pair.
Q: What is the difference between compatible and OEM transceivers?
A: Compatible transceivers (also called third-party or generic optics) meet identical MSA specifications as OEM modules but are manufactured independently. They offer equivalent performance at lower cost. Our modules are coded to work with your specific switch brand.
Q: Do I need to change switch settings for compatible optics?
A: Most enterprise switches support compatible transceivers natively. Cisco devices may require the "service unsupported-transceiver" command on older IOS versions. Juniper and Arista platforms typically work without configuration changes. Contact us for platform-specific guidance.
