Deploy industry-standard compatibility and optimal power efficiency. These top modules are engineered to serve the high-capacity demands of Sri Lankan metropolitan networks and localized edge clouds.
Sri Lanka's telecommunications sector is witnessing a rapid structural upgrade. Led by national giants like SLT-Mobitel and Dialog Axiata, the nation is actively transitioning from legacy 10G networks directly to 25G (SFP28) and 100G edge topologies. This transition is critical to support the ongoing 5G commercial rollouts and localized content distribution networks (CDNs). SFP28 modules utilize a single 25Gb/s lane, allowing operators to reuse existing optical fiber infrastructures built for 10G SFP+ while gaining 2.5 times the bandwidth capacity.
For SAN (Storage Area Network) architectures in Colombo’s emerging IT hubs and data facilities—such as the Pitipana Tier III Data Center and Colombo Port City Smart Zone—32G SFP28 Fibre Channel (FC) modules represent the premium tier of low-latency data transport. By deploying SFP28 modules with Digital Diagnostic Monitoring (DDM/DOM), Sri Lankan network engineers can remotely analyze real-time variables such as laser temperature, optical output power, receiver power, and supply voltage, ensuring robust protection against tropical humidity-induced link failures.
Global corporations outsourcing IT/BPM operations to Sri Lanka require secure, compliant, and highly stable connectivity. When routing heavy enterprise traffic, standard optical modules can struggle with heat dissipation in humid climates. Our high-reliability transceivers are configured with internal components that resist operational temperature rises up to 85°C (industrial grade) and feature power-saving designs under 1.2 Watts. This translates to prolonged hardware longevity and lower operational expense (OpEx) for local colocations and hyper-scale hubs.
| Factor | 10G SFP+ | 25G SFP28 | 32G SFP28 FC |
|---|---|---|---|
| Line Rate | 10.31 Gbps | 25.78 Gbps | 28.05 Gbps |
| Interface Lane | 1 Lane x 10G | 1 Lane x 25G | 1 Lane x 28G/32G | Typical Power | ~1.0 W | 1.0W - 1.5W | 1.2W - 1.8W |
Maximize fiber resource utilization using single-fiber Bidirectional (BiDi) and Coarse Wavelength Division Multiplexing (CWDM) modules, custom-fit for Sri Lanka's metropolitan network backbones.
Established in 2016, Novafiber Communications Co., Ltd. is a world-class optical transceiver manufacturer delivering high-performance fiber optic solutions for telecom carriers, data center infrastructures, and global enterprise platforms.
Our engineering standards require 100% functional, parameter-swept testing, high-temperature burn-in protocols, and Environmental Stress Screening (ESS). Employing 65 quality control experts, we ensure every optical module conforms strictly to IPC standard specifications and global safety regulations (CE, FCC, RoHS). Customization remains our central capability, offering personalized firmware programming, wavelength configurations, and multi-platform protocol adaptation (Cisco, Juniper, Arista, Dell, HP) to match the diverse switch portfolios of Sri Lankan IT networks.
Novafiber supports high-velocity product launches, documenting 320 custom and standard releases over the past year. From entry-level 1G transceivers to state-of-the-art 800G PAM4 optics, our solutions support operators in optimizing legacy multi-mode fibers (MMF) or leveraging long-reach single-mode fibers (SMF). In Colombo, Kandy, or Hambantota, we back global integrations with reliable export networks, providing stable lead times and localized project advice.
Individually programmed EEPROMs verify handshakes with switch vendors such as Cisco, Arista, Juniper, HP, and Dell, eliminating firmware incompatibility alarms during deployment.
Digital Diagnostic Monitoring monitors transceiver parameters, facilitating proactive link troubleshooting, isolation of optical power dropouts, and prevention of thermal downtime.
SFP28 systems establish the path to high-density SFP56 (50G PAM4) and SFP112 (100G) form-factors, easing transition curves as local network backbones scale up.
Select from our verified range of long-reach single-mode, multi-mode, CWDM, DWDM, and Cisco-compatible transceivers, designed to support modern network topologies.
Importing critical networking equipment into Sri Lanka requires navigating regulatory standards and customs frameworks, including imports through the Port of Colombo or Bandaranaike International Airport (BIA). Novafiber maintains export structures compliance-aligned with Sri Lankan Telecommunications Regulatory Commission (TRCSL) guidelines and customs procedures. By providing complete documentation—including RoHS reports, CE/FCC declarations, certificates of origin, and custom HS code documentation—we minimize clearing times and administrative friction.
Our transport model relies on established cargo networks (DHL, FedEx, UPS, or air freight forwarders) to guarantee arrival in Colombo, Kandy, and surrounding tech corridors. Optical modules are sealed in anti-static protective cases and shock-absorbent shipping cartons to prevent mechanical strain, humidity damage, and electrostatic discharges (ESD) during transit.
Furthermore, local network deployments often face high relative humidity and warm conditions. Novafiber's R&D integrates industrial-grade PCB components, high-durability VCSEL lasers, and high-performance PIN/APD photodetectors. Each SFP28 module is designed to operate under these localized conditions. To support enterprise SLA guarantees, we offer technical consulting, remote troubleshooting, and replacement warranties, ensuring network operations remain reliable and downtime is minimized.
For custom engineering projects requiring tailored software configurations (such as distinct EEPROM addressing or non-standard wavelength spacing), our engineering team coordinates directly with your engineering leads to run laboratory pre-testing and prototype runs prior to commercial production.

Generally, standard 25G SFP28 modules do not auto-negotiate down to 10G unless the module itself is dual-rate (like the Cisco SFP-10/25G-CSR-S Compatible) and the hosting switch port is explicitly configured to support 10Gb/s rate-limiting. Check switch firmware compatibility before attempting to run 25G hardware in legacy 10G sockets.
High relative humidity can accelerate oxidation on gold-plated connector pins and increase the risk of condensation if temperatures drop quickly. Novafiber addresses this by using high-grade gold finger plating and sealed optical components, ensuring stable operation even in coastal, non-climate-controlled environments.
25G SFP28 is designed for Ethernet protocols (IEEE 802.3by) widely used in data centers and telecom backbones. 32G SFP28 is optimized for Fibre Channel protocols (FC-PI-6) running at a lane speed of 28.05 Gbps, which is standard for high-speed Storage Area Networks (SANs) and enterprise database storage arrays.
Yes. Every transceiver is programmed with vendor-specific EEPROM configuration data. They are tested on actual brand switches (Cisco, Arista, Juniper, HP, Dell) in our laboratories to confirm that the hosting hardware recognizes the module and reads the Digital Diagnostic Monitoring (DDM) data correctly.
For standard stocked configurations, packaging and dispatch take 1–3 business days. Transit time via standard express air freight (DHL/FedEx) to Colombo is typically 5–7 business days, depending on customs clearing protocols at the airport or seaport.
