Frequently Asked Questions
1. What is a BiDi SFP module and how does it work?
BiDi (Bidirectional) SFP modules allow for data transmission over a single strand of optical fiber by using two different wavelengths (TX and RX) to separate the upstream and downstream signals.
2. Can I get a sample for testing before placing a bulk order?
Yes, samples are available for quality testing. Please reach out to our team to discuss sample availability and shipping arrangements.
3. What is the typical lead time for these transceiver modules?
Stock items are ready for immediate shipment. For bulk production or customized orders, the typical delivery time ranges from 15 to 30 days.
4. Does this module support Digital Diagnostic Monitoring (DDM)?
Yes, this module supports DDM/DOM according to the SFF-8472 standard, allowing real-time monitoring of parameters like temperature and optical power.
5. What kind of warranty is provided with your optical modules?
We offer a 5-year warranty on our optical transceiver modules, along with 24-hour online technical support to ensure network reliability.
6. Are these modules compatible with different temperature environments?
Yes, we provide both commercial grade (0 to 70°C) and industrial grade (-40 to 85°C) versions to meet various deployment requirements.
