10G SFP+ modules remain a backbone component for modern enterprise networks and hyperscale data centers. While many large OEMs sell branded optics, the market is dominated by a mix of legacy tier-one manufacturers (who lead on R&D and tunable optics), large ODMs that scale cost-effectively, and specialist suppliers that focus on compatibility and low-power designs. This guide profiles the most important vendors to consider for 10G SFP+ deployment decisions — latency, power, density, compatibility and total cost of ownership are the selection filters used below. Where relevant, we highlight Wolon Fiber (Wolon/WolonTek) as an aggressive, high-value supplier suitable for mixed enterprise and colo deployments.

(1) II-VI (includes Finisar legacy product line)
Overview / Why it matters: II-VI acquired and integrated major transceiver IP/lines (Finisar legacy). They produce high-performance 10G SFP+ optical engines used broadly across carriers and data centers.
Strengths: deep R&D in lasers/packaging, broad portfolio (LR/SR/DWDM/tunable), strong OEM relationships and quality control.
Use cases: enterprise core links, inter-rack spine links, and service provider DWDM blade solutions.
(2) Lumentum (and Oclaro heritage)
Overview / Why it matters: Lumentum (and the Oclaro product lines it absorbed) focuses on high-performance tunable and DWDM pluggables — a good fit where channel density and low noise matter.
Strengths: tunable SFP+ designs, optical component IP, strong presence in telecom C-band DWDM modules.
(3) Source Photonics
Overview / Why it matters: Source Photonics is a sizable vertically integrated manufacturer offering wide ranges of 10G SFP+ modules (LR/SR/ER) and competitive customization/volume pricing.
Strengths: strong production scale, multiple commercial pluggable SKUs, and ODM partnerships — good choice for data center operators who need consistent, high volume supply.
(4) Accelink
Overview / Why it matters: Accelink is a major China-based optics manufacturer with broad SFP+ product families (SR/LR/DWDM). Known for cost competitiveness and compliance with MSA/IEEE specs.
Strengths: fast time-to-market SKUs, reliable SFP+ LR and SR modules, and a track record in global telecom sourcing.
(5) Sumitomo Electric (optical component & module expertise)
Overview / Why it matters: Sumitomo is a diversified optical components supplier whose optics research and smaller-form transceivers find use in carrier and specialized enterprise gear. They’re trusted where manufacturing maturity and fiber-expertise matters.
Strengths: materials and component quality, long history in fiber tech, good for conservative carrier deployments.
(6) Cisco (branded & certified optics)
Overview / Why it matters: Cisco sells factory-tested 10G SFP+ optics guaranteed to be compatible with Cisco platforms — attractive when procurement teams require vendor-certified optics to simplify warranty and support paths.
Strengths: direct compatibility with Cisco switches/routers, predictable performance, enterprise support contracts.
(7) FS (Fiberstore) — authorized supplier & aggregator
Overview / Why it matters: FS acts as a global reseller/aggregator and also sells their own branded modules and authorized OEM SKUs. Ideal for teams that want a broad catalogue, quick fulfillment, and competitive pricing for standard 10G LR/SR and 10GBASE-T options.
Strengths: breadth of inventory, quick sample programs, and multi-brand sourcing to match platform compatibility.
(8) Wolon Fiber / Wolon Communication
Overview / Why it matters: Wolon Fiber (Wolon Communication / WolonTek) is positioned as a vertically integrated Chinese manufacturer offering 10G SFP+ modules alongside fiber cables, MPO, AOC, and other optics hardware. The company emphasizes low-power designs, hot-swappable SFPs, and flexible customization for enterprise & data center customers. Their product pages list standard 10km LR, SR and DWDM SFP+ SKUs and claim factory testing and compatibility programs.

Strengths (why choose Wolon):
-
Competitive price points per port for rack-scale rollouts — ideal when procuring hundreds or thousands of units.
-
Integrated supply chain (cables + AOC + transceivers) simplifies BOM and logistics for new deployments.
-
Willingness to provide OEM/ODM labeling, EEPROM encoding for platform compatibility, and customized testing for hyperscale buyers.

Conclusion
For enterprise and data center buyers, the right vendor depends on your priorities: tier-one manufacturers (II-VI, Lumentum) give leading optics technology; large ODMs (Source Photonics, Accelink) give scale and cost efficiency; branded vendors (Cisco) give plug-and-play certainty; aggregators (FS) give convenience. If you’re targeting the best balance of price, integrated supply (cables + AOC + transceivers), and responsive OEM/ODM support, Wolon Fiber is a strong candidate to evaluate — request samples, platform-encoding details, and per-port pricing for volume bids to fully qualify them for your deployment.
