Sanoc 1000Base-T SFP RJ-45 Copper transceivers go through environmental stress screening and reliability validation in manufacturing, followed by FQC and OQC inspection according to the applicable sampling plan before shipment. Our modules are backed by a comprehensive warranty and technical support.
Hear from networking professionals who trust Sanoc transceivers in their infrastructure.
The following is past customer feedback.
“Sanoc's SFP modules have been a perfect fit for our data center. The compatibility with our existing equipment was seamless, and we've experienced zero failures in over a year of operation.”
“As an ISP, we require reliable components for our network. Sanoc's transceivers have delivered exceptional performance, and their technical support team has been responsive whenever we needed assistance.”
“The value proposition from Sanoc is impressive. We've reduced our hardware costs significantly without compromising on quality or performance. Delivery times are consistently reliable.”
When a switch or network adapter needs to connect to existing copper cabling, first confirm that the equipment supports a 1000BASE-T SFP. For a replacement, keep the full part number and a photograph of the installed module label with the equipment model.
Check the required port speed and electrical mode in the equipment documentation, then describe the cable and patch-panel arrangement for the proposed link.
The specification table lists SI0012-X1ATXX at 0~70° and SI0012-X1ATXX-WT at -40~85°. Both series have entries marked “1000” and “10/100/1000”. Include the required connection mode and operating temperature when identifying the configuration for an inquiry.
All four entries list RJ45 and a distance of 100M. Confirm the configuration with the complete part number, and evaluate the actual cable, connections and equipment together.
Provide the full device model, port and software or firmware version. Use the device documentation to check port speed, PHY and electrical-interface requirements. Include cable type, actual length, patch cords and patch-panel arrangement.
Check installation clearance and thermal conditions. During qualification, record module recognition, link status and error counters so the cable, port settings and module can be evaluated as one connection.
SANOC can assist with compatibility review for specified equipment, ports, software, protocol and module part number. Results apply only to the combination actually validated. EEPROM coding can be evaluated for the product and project; it cannot change port speed, PHY, electrical interface or protocol capability.
A complimentary sample may be requested for the product and project. Only the sample itself is complimentary; shipping and freight are confirmed separately. FQC and OQC follow the product, lot size and applicable sampling plan after production and before shipment. OQC includes visual inspection.
Send company and contact details, quantity, equipment model, port mode, cable type and length, operating temperature, and the installed or proposed module part number. Equipment documentation and a cabling sketch are useful when the configuration is still being selected.
The formal quotation and order records confirm the complete part number, applicable datasheet revision, supply and delivery terms. Warranty, DOA and after-sales conditions follow the quotation, order terms or product warranty policy.
The listed configurations include different connection-mode descriptions under the same series identifier. Keep the agreed configuration description with the order and maintenance record rather than relying on the series text alone. Compare the required host behavior with the copper peer's settings. A working cable-side negotiation does not establish that the host uses the required interface mode. For an installed replacement, preserving both the module label and the original configuration description helps avoid a physically fitting but functionally different substitution.
If the equipment does not recognize the module, investigate the host's module support and configuration first. If recognition succeeds but the copper link does not establish, inspect the peer settings and cable path. If the link establishes but errors accumulate, retain the counters and compare with a known-good patch lead under the same traffic conditions. Change one item at a time. This keeps identification problems, cabling problems and traffic problems distinguishable instead of treating every failure as a defective module.
A channel can change when a patch cord or panel connection is replaced even though the permanent cable remains in place. Record these small changes with the negotiated state and error counters. For spare qualification, use the intended host and the actual copper route, including the normal neighboring-port population and airflow conditions. Keep the accepted configuration linked to that result so procurement and maintenance can order against a tested requirement rather than a general RJ45 description.
Common questions about our 1000Base-T SFP RJ-45 Copper transceivers
Choose the part number that matches the actual link length, then check loss and margin against the values in the specification table.
The operating temperature: standard parts are rated 0 to 70°C, industrial parts -40 to 85°C for outdoor cabinets or large temperature swings.
Our commercial grade 1000Base-T SFP RJ-45 Copper modules operate reliably within 0°C to 70°C, suitable for standard office and data center environments. For harsh conditions, we offer industrial grade options that function in -40°C to 85°C, ideal for factory automation, outdoor installations, or extreme temperature environments.
Yes. A complimentary sample is available for testing on your equipment; only the sample itself is complimentary, and shipping and freight are confirmed separately.
EEPROM coding can be evaluated for the equipment model and project. Coding affects identification only; it does not change speed or transmission capability.

After production and before shipment, SANOC performs FQC and OQC inspections according to the product, lot size, and applicable sampling plan. OQC includes a pre-shipment visual inspection. Inspection items, sample quantities, and available quality documentation are confirmed based on the product and order requirements.
Before shipment, FQC and OQC inspections are performed according to the product, lot size and applicable sampling plan; production also includes environmental stress screening (temperature cycling, humidity testing) and reliability checks (vibration, shock resistance). We also conduct compatibility tests with major equipment brands to ensure plug-and-play functionality.
Do one more check before deployment: link speed and duplex mode, cable category and length, module temperature and compatibility with the target platform.
Absolutely. Our standard 1000Base-T SFP modules provide connectivity up to 100 meters over CAT5e cabling; we also provide customized solutions for your request. Please provide the exact module part number to confirm its power consumption.
