DWDM-SFP-5736 Use Case
High-Capacity Data Center Interconnect Over DWDM
In a multi-data-hall campus, network architects deploy DWDM-SFP-5736 (1557.36 nm, 100 GHz ITU grid) to aggregate 100 GbE links across an 80 km metro fiber span. This module’s precise wavelength alignment and low insertion loss ensure transparent, high-throughput connectivity between core switches. Benefit: Scalable DCI with sub-1 dB loss per channel, reduced rack space and power consumption, and seamless capacity growth without dark-fiber leasing.
Resilient Metro Ethernet Ring for Service Providers
A regional carrier implements a bi-directional Metro Ethernet ring using DWDM-SFP-5736 transceivers at 1557.36 nm to carry multiple 10 GbE and 100 GbE customer circuits over existing fiber. The 100 GHz ITU grid spacing enables dense channel packing and automated wavelength provisioning. Benefit: Rapid service turn-up, sub-50 ms protection switching, and maximized fiber utilization drive higher revenue per fiber pair with carrier-grade reliability.
High-Density Campus Backbone Aggregation
In a university campus network, IT teams deploy DWDM-SFP-5736 modules in 1U aggregation switches to connect distributed research labs up to 40 km away. The 1557.36 nm wavelength slot on the 100 GHz grid supports seamless mux/demux integration and centralized traffic management. Benefit: Simplified infrastructure with converged DWDM overlay, predictable latency for real-time applications, and easy capacity scaling for future bandwidth demands.

Questions & Answers
What is the DWDM-SFP-5736 module?
The DWDM-SFP-5736 is a hot-pluggable SFP transceiver operating at 1557.36 nm on a 100 GHz ITU grid for DWDM single-mode fiber applications.
Which ITU channel corresponds to 1557.36 nm?
The 1557.36 nm wavelength aligns with ITU DWDM channel 36 on the 100 GHz grid in the C-band spectrum.
What data rates does this DWDM SFP support?
It supports standard rates from 100 Mbps up to 4.25 Gbps, making it compatible with Fast Ethernet, Gigabit Ethernet, and SONET/SDH.
What is the maximum reach over single-mode fiber?
Over standard ITU-T G.652 single-mode fiber, it supports link spans up to 80 km without in-line amplification.
What type of fiber and connector does it use?
It operates on ITU-T G.652 single-mode fiber with a duplex LC connector interface.
Is the DWDM-SFP-5736 module hot-swappable?
Yes, it is fully hot-pluggable and can be inserted or removed without powering down the host device.
Does it support digital diagnostics (DDM)?
Yes, it provides real-time monitoring of optical power, temperature, voltage, and bias current via the SFF-8472 DDM interface.
What operating temperature range does it support?
It is rated for a commercial temperature range of 0 °C to 70 °C (32 °F to 158 °F).
Is the module RoHS and Telcordia compliant?
Yes, it meets RoHS Directive 2011/65/EU and Telcordia GR-1209/GR-1221 reliability standards.
Which equipment brands are compatible with this SFP?
It is interoperable with major DWDM-capable switches, routers, and optical multiplexers from Cisco, Juniper, Arista, Huawei and other MSA-compliant vendors.
How do I install the DWDM-SFP-5736 in my switch?
Power up the device, align the LC connector, insert the SFP until it locks, then configure the port to use 1557.36 nm DWDM mode.
Can this module coexist with CWDM SFPs on the same fiber?
No. DWDM and CWDM use different channel spacings and cannot be multiplexed without separate DWDM or CWDM MUX/Demux equipment.
What is DWDM and how does it differ from CWDM?
DWDM (Dense WDM) uses narrow channel spacing (100 GHz) for higher channel counts, while CWDM (Coarse WDM) uses wider spacing (20 nm) for simpler, lower-capacity links.
How can I troubleshoot a DWDM link using this SFP?
Verify correct ITU channel configuration, check LC connections, monitor DDM parameters for power or temperature alarms, and ensure the remote end uses the matching wavelength.
Where can I find the technical datasheet for the DWDM-SFP-5736?
You can download the full specifications and mechanical drawings from the manufacturer’s website or request a PDF from your authorized distributor.
Does this module require additional optical amplification?
For spans under 80 km on standard single-mode fiber, no amplification is needed; longer distances may require EDFAs or Raman amplifiers.
