In the rapidly shifting landscape of enterprise networks and cloud computing infrastructures, the demand for scalable, robust, and cost-effective fiber interconnect solutions has never been more critical. The 10GBASE-LR SFP+ optical transceiver stands as the primary workhorse for 10 Gigabit Ethernet deployments over single-mode fiber (SMF) links up to 10 kilometers. Utilizing a nominal wavelength of 1310nm, this transceiver architecture balances performance, heat dissipation, and module longevity, making it indispensable for metropolitan access, datacenter aggregation, and corporate backbones.
As a premier communication developer and manufacturer, Kocent Optec Limited (established in 2012 in Hong Kong) provides custom OEM and ODM solutions designed to fit seamlessly into any system. By leveraging advanced optoelectronic assembly lines, exhaustive testing matrices, and multi-vendor compatibility engineering, Kocent Optec ensures that our partners receive components that minimize cost while maximizing optical link margin.
"Our objective is clear: to deliver highly stable transceivers that match or exceed the original system provider specifications at a fraction of the cost, backed by a comprehensive engineering warranty."
While higher speed protocols like 100G and 400G capture headlines, 10G LR SFP+ remains the backbone of operational networks globally. Its stability, low latency, and low power budget make it the primary link choice for various macro-industry settings:
Enables cellular service providers to run robust backhaul networks connecting cell towers (eNodeB/gNodeB) back to central offices over distances up to 10km without signal regeneration.
Bridges core network switches across distinct physical buildings in education, healthcare, and industrial campuses, preserving link integrity in electrically noisy environments.
Manages Leaf-Spine connections, connecting access switches at the Top-of-Rack (ToR) to central aggregation layers that reside in adjacent buildings or distant halls.
Kocent Optec Limited takes pride in employing mature scientific testing protocols that guarantee 100% of our products undergo evaluation prior to shipping. Our 10G LR SFP+ transceivers are validated under varied ambient temperatures, structural stresses, and software parameters to match Multi-Source Agreements (MSA) standards.
Every module integrates a premium 1310nm DFB (Distributed Feedback) laser diode alongside a highly responsive PIN photodetector. Together, they provide reliable performance across standard temperatures (0°C to 70°C) or extended industrial operational matrices (-40°C to 85°C). By implementing Digital Diagnostics Monitoring (DDM/DOM), network engineers can real-time track key performance parameters, including optical transmit power, optical receive power, internal temperature, and bias current.

Managing cost structures while sustaining high quality is a challenge faced by procurement teams worldwide. By cooperating directly with our OEM factory in China, system builders and telecom operators circumvent the heavy markups associated with original system providers. We offer customized labeling, pre-coded EEPROM memory for compatibility, and bulk pricing schedules designed to scale.
Our manufacturing plant utilizes cleanrooms alongside robotic alignment stations. Because raw material costs, silicon fabrication processes, and global transport timelines directly impact component pricing, Kocent Optec optimizes every step of production. Our volume capability shields buyers from sudden component shortages, ensuring that active infrastructure projects proceed on schedule.
By leveraging our production capacity developed over the years, we magnify the outcome for our customers. This expands their core competencies and helps them outperform competitors in tender situations.
Our OEM and ODM components have successfully won operator tenders, fulfilling demanding end-user requirements. We support and supply parts compatible with architectures managed by operators globally, including:
Deployments vary by geography, environment, and regional regulations. In European enterprise zones, strict adherence to RoHS, REACH, and WEEE directives is mandatory. In North American data centers, UL standards and FCC Part 15 compliance determine procurement acceptance.
Kocent Optec designs transceivers to comply with these global standards, enabling deployments in diverse localized situations:
While 10G LR remains widely deployed, network architectures are transitioning toward higher data rates. Kocent Optec has developed product paths mapping this transition. System engineers can scale using:
25G SFP28 LR modules, which triple throughput over existing 10G single-mode fiber runs, leveraging similar power and thermal footprints. For aggregation layers, 100G QSFP28 Single-Lambda transceivers offer efficient, direct-detect technology that reduces system cost-per-bit. Our R&D division focuses on integrating Silicon Photonics (SiPh), reducing footprint and optical assembly tolerances, and supporting green initiatives with energy-efficient module design.
Every switch manufacturer utilizes distinct EEPROM coding parameters to authenticate transceivers. Our engineering team maintains a lab equipped with original host switches from major brands. Before shipment, each OEM module is configured with matching software keycodes, ensuring seamless integration and preventing system warnings or interface lockouts.
FP (Fabry-Perot) lasers exhibit broad spectral widths and are typically suited for shorter distances. For 10GBASE-LR transceivers targeting 10km distances, Kocent Optec uses DFB (Distributed Feedback) lasers. DFB lasers restrict optical emission to a single wavelength mode, reducing chromatic dispersion penalty and ensuring reliable performance over single-mode fiber.
10GBASE-LR transceivers are optimized for Single-Mode Fiber (9/125µm). While they can run over Multi-Mode Fiber, a mode-conditioning patch cord is typically required to avoid differential mode delay. For multi-mode deployments, 10G LRM (Long Reach Multimode) or SR (Short Reach) transceivers are recommended.
Digital Optical Monitoring (DOM) provides real-time readouts of optical transmit power, receive power, laser bias current, internal module temperature, and voltage. This allows network administrators to proactively detect fiber bend losses, dirty connectors, or aging lasers before a link failure occurs.
OEM pricing structures depend on several factors: the quantity per production batch, required testing regimes, custom packaging, labeling requirements, and the compatibility code profile. We offer competitive tiered pricing structures for system integrators and telecommunication operators.
We maintain unified inspection guidelines for both active transceivers and passive components (e.g., MTP/MPO trunk cables, attenuators, PLC splitters). Our testing includes geometric end-face inspections, insertion loss mapping, and return loss verification to ensure complete link performance.
