FAQ
Q:

What should a wholesale SFP module RFQ include to reduce wrong shipments and returns?

A:
List quantity by exact rate, optical standard, wavelength or BiDi pair, reach, fiber type, connector, temperature grade and DOM requirement. Include target switch models and software versions, labeling and packing needs, and required test or compliance documents for each model. Confirm sample approval, delivery date, warranty terms, compatibility acceptance criteria and replacement procedure in writing. Keep the approved part number and coding specification on repeat orders, and require approval before substitutions.
Q:

How can overseas distributors verify SFP modules before shipment?

A:
Agree a sample and acceptance checklist tied to each part number and host platform. Request serial-numbered labels, EEPROM identification and, where supported, DOM screenshots plus a dated traffic-test video or report showing the switch model, software, port speed, test duration and error counters. Verify optical power against the exact datasheet and label complementary BiDi ends if ordered. A link LED alone does not demonstrate full-rate stability or compatibility across all switch models.
Q:

Do SFP transceivers include DOM/DDM monitoring and industrial temperature ratings?

A:
DOM/DDM and temperature grade must be confirmed for the selected module, not assumed for the whole product family. Where both module and host support it, diagnostics can report values such as optical transmit/receive power, temperature, supply voltage and laser bias. Ask for supported readings and alarm thresholds. For outdoor or unconditioned equipment, request the exact operating-temperature specification and verify the host environment; a diagnostic display is not proof of industrial-grade qualification.
Q:

Can a long-reach SFP module be used on a short fiber link?

A:
Only if received optical power stays within the exact receiver operating range. A stronger long-reach transmitter is not automatically a better choice: a short low-loss link may overload the receiver. Check both worst-case sensitivity and overload limits using the model-specific minimum and maximum transmit power and link loss. Where necessary, specify an optical attenuator and verify received power; do not choose an attenuator value from distance alone.
Q:

How should buyers specify duplex or single-fiber BiDi SFP modules?

A:
For a conventional duplex optical link, connect the transmitter at each end to the receiver at the other using two fibers and matching optical standards. If a single-fiber BiDi option is required, confirm availability and order a complementary wavelength pair: one end transmits at the wavelength the other receives. Both ends must also match in rate, optical specification and reach. State connector type and label the A/B ends to avoid incorrect pairing in distributor stock.
Q:

How should distributors select multimode or single-mode SFP transceivers and reach?

A:
Select an optical standard that matches the fiber type, link length and equipment at both ends. Multimode reach depends on fiber grade and data rate; single-mode reach depends on the exact optics and link conditions. Do not apply one family-level distance table to every 1G and 10G module. Confirm wavelength, connector, fiber count and maximum channel loss, then include connectors, splices and engineering margin in the link budget.
Q:

What is the difference between a 1.25G SFP and a 10G SFP+ optical module?

A:
A 1.25G SFP commonly refers to the optical line rate used for 1 Gigabit Ethernet; a 10G Ethernet optical module normally uses SFP+. Similar dimensions do not make them interchangeable in speed. Some SFP+ ports accept supported 1G SFPs, but this depends on the host and software. Do not assume a 10G module can run in a 1G-only port or that an optical module provides 10/100/1000 auto-negotiation. Request a separate datasheet for each ordered rate and model.
Q:

How can buyers verify SFP compatibility with Cisco, H3C or Huawei switches?

A:
Provide the exact switch model, line card or port, operating-system version and required transceiver type. Matching the brand name or physical SFP slot is not enough: port speed, host support and module coding also matter. Request compatibility confirmation for that combination and approve a sample on the intended equipment before a bulk order. A compatible third-party module should not be described as an original Cisco, H3C or Huawei product.
