10 Gb/s LR in SFP+ — 1310 nm, 10 km over OS2 single-mode. Vendor-coded and traffic-tested on a live switch before shipment.
10 km single-mode 10G — the universal campus and metro access optic.
Built to IEEE 802.3ae 10GBASE-LR, this module presents a Duplex LC optical interface and runs over OS2 single-mode. Every unit is programmed to your platform's vendor coding, powered up on a live switch and traffic-tested end-to-end before it is packed — so it links up on first insertion rather than throwing an “unsupported transceiver” message at 2 a.m.
Full DDM/DOM telemetry is implemented, so per-lane transmit and receive power, laser bias and case temperature are readable live from your NOS. Modules are serialized, individually bagged with dust caps, and covered by a 3-year warranty. OEM/ODM labelling and custom EEPROM profiles are available on request.

How to read this table. 10G SFP+ LR 10km Optical Transceiver is an FOT-manufactured module built to IEEE 802.3ae 10GBASE-LR. The part numbers above identify the OEM optics it is designed to function in place of; they are listed for compatibility reference only and remain the trademarks of their respective owners. This is not an OEM-branded product. Send us your platform and software version and we programme and traffic-test to match it.

Need a wavelength, channel or coding that is not listed? Custom builds ship in 5–7 days — note it on your RFQ.
Every module is EEPROM-programmed at the factory to the vendor coding you specify, so the host recognises it natively — no “unsupported transceiver” warnings and no console workarounds. Mixed coding (a different vendor at each end) is available for inter-vendor links.
Every module is linked on a live switch and BER-verified end-to-end before packing.
Serial number links to the test record, coding profile and production batch.
Qualify the module on your own platform before committing to a volume order.
Individually bagged with dust caps and ESD protection, packed in export cartons.
High-radix switching fabrics where port density and power per bit decide the design.
Rail-optimised accelerator fabrics running InfiniBand or RoCE at scale.
Campus backbone and data-centre interconnect over leased or owned dark fibre.
Core uplinks, SAN fabrics and aggregation for campus and enterprise networks.
Yes. This is a third-party module built to the same IEEE 802.3ae 10GBASE-LR specification and EEPROM-coded so the host reads it as a supported optic. It is offered as a functional equivalent to SFP-10G-LR, SFPP-10GE-LR, J9151A — it is an FOT module, not an OEM-branded part. Tell us the exact switch model and software version on your RFQ and we code and traffic-test against that platform before shipping.
This module is specified to 10 km. Real-world reach depends on your channel loss budget — every mated connector pair costs roughly 0.3 dB and every splice about 0.1 dB. Measure the installed channel rather than assuming the map distance, and keep 2–3 dB of margin for ageing and future repairs.
Yes. We program the EEPROM at manufacture for NVIDIA/Mellanox, Cisco, Arista, Juniper, Huawei, HPE, Dell, Extreme and generic MSA. Specify the platform on your RFQ; mixed coding (a different vendor at each end) is routine for inter-vendor links.
Free samples are available so you can qualify the module in your own environment before committing to volume. Per-order test reports are supplied on request, and sample reports can be provided for tender documentation.
Tell us the platform and the quantity. An engineer checks the part against your switch and software version before quoting — if it will not work, we say so.
