The BiDi SFP Transceiver is a pin-to-pin drop-in replacement for Extreme OEM SFP-1GBX-D-SC-EX, delivering stable 1.25Gbps single-fiber bidirectional transmission up to 20km over standard 9/125μm SMF. Equipped with simplex SC port and Tx1550/Rx1310 wavelength design, it halves fiber core consumption to cut deployment costs for enterprise campus, FTTx and long-distance IP monitoring systems.
Compliant with SFP MSA SFF-8431/SFF-8472 and IEEE 802.3z global standards, this Extreme compatible BiDi SFP Transceiver supports real-time DDM/DOM digital monitoring and safe hot-swap operation. Every unit passes 24-hour continuous aging testing to maintain error-free gigabit performance for permanent commercial rack deployment.
3. Free Custom EEPROM & Bulk OEM Service
We provide free EEPROM firmware rewrite and basic OEM labeling for all BiDi SFP Transceiver bulk orders. Preload matched vendor ID data to remove transceiver error alerts; custom packaging available for large-scale projects with zero hidden fees.

Connectivity Solutions (Applications)
1. 1G Link for Switch to Switch
2. Double Your Network Capacity
Bidirectional transmission on a single fiber strand effectively doubles link capacity without laying new fiber cables. It provides a low-cost, high-efficiency bandwidth expansion solution for Extreme enterprise network upgrades and operator FTTx optimization.
3. Stable 1G Connectivity: The Groundwork for High-Availability Data Centers
In an era where data centers are scaling to 100G, 400G, and beyond, the stability of your underlying 1G infrastructure remains the true backbone of operational continuity. Our enterprise-grade BiDi SFP Transceiver 1G connectivity solutions are engineered to deliver rock-solid, low-latency performance where reliability matters most.
From critical Out-of-Band management to real-time environment monitoring, we ensure your control plane is always online, always stable, and completely isolated from production traffic spikes.

Every batch of this BiDi SFP Transceiver undergoes full real-machine compatibility testing on Extreme, Huawei, H3C and other mainstream hardware. We verify link handshake stability, DDM precision and hot-swap performance under real network load, eliminating all on-site compatibility risks.
5. Comprehensive Testing
Each BiDi SFP Transceiver passes strict standardized QC tests including high/low temperature aging, repeated plugging durability, optical power consistency and 72-hour continuous operation testing. Rigorous mass production inspection guarantees consistent batch performance and long service life for commercial deployments.
FAQ
Q1: Will future switch firmware upgrades break compatibility of these third-party BiDi SFP transceivers?
A1: Our HYTOPTODEVICE BiDi SFP Transceiver follows universal MSA specs with fixed preloaded Extreme vendor ID coding. Regular EXOS firmware updates will not trigger compatibility failures, and we supply free re-flashing support if rare recognition issues arise after system upgrades.
Q2: Will this BiDi SFP Transceiver lose signal sync when connected to outdated legacy single fiber media converters?
A2: This transceiver uses standard gigabit WDM timing circuits to sustain stable signal synchronization with most aging media converter hardware. We offer complimentary pre-deployment compatibility testing for older legacy equipment before bulk shipment.
Q3: How much extra optical insertion loss will tiny dust particles or inferior SC end-face polishing create on connection interfaces?
A3: Every BiDi SFP Transceiver undergoes factory UPC precision polishing, and matching dust caps block surface dust buildup. Minor dust or imperfect polishing will only generate negligible extra loss and will not trigger unstable link attenuation under normal deployment.
Q4: Can the built-in 1310nm and 1550nm laser assemblies retain steady optical power after multiple years of non-stop 24/7 rack operation?
A4: Each BiDi SFP Transceiver passes long-duration aging testing to validate laser power consistency. Built-in temperature compensation circuits slow laser attenuation, maintaining stable output power during multi-year continuous running.
Q5: Will this transceiver overheat and sustain permanent damage inside compact, low-airflow dense switch racks?
A5: Full metal heat dissipation housing and internal thermal protection circuits avoid overheating risks. This Extreme matching BiDi SFP Transceiver automatically adjusts laser power to lower heat generation in cramped poorly ventilated cabinet environments.
Q6: Can this transceiver’s temperature tolerance withstand extreme temperature swings inside uncooled outdoor industrial cabinets?
A6: This commercial-grade BiDi SFP Transceiver operates reliably between 0℃ and +70℃, designed for indoor rack deployment. For unconditioned outdoor industrial cabinets with wide temperature fluctuations, we provide dedicated industrial temperature optical modules as an alternative solution.
Q7: Are the attached protective dust caps tight enough to stop optical surface contamination before field installation?
A7: Each BiDi SFP Transceiver comes with custom-fit elastic SC dust caps that firmly cover the optical end face. The secure fit blocks dust, fingerprints and minor debris during storage and pre-deployment handling.
Q8: Will the manufacturer swap internal chipsets and core components without updating the official SFP-1GBX-D-SC-EX product SKU?
A8: We maintain fixed component BOM for this Extreme compatible BiDi SFP Transceiver. Any internal component modification will update product specifications and notify all bulk clients in advance; no unmarked silent part replacement for large orders.
Q9: Does the product packaging offer sufficient shock and anti-static protection to safeguard fragile optical chips during cross-border long-distance shipping?
A9: Every BiDi SFP Transceiver is individually sealed in anti-static shockproof boxes paired with SC dust caps. Thick buffered outer cartons with filler materials prevent collision and contamination damage across international logistics transportation.
Q10: Can this BiDi SFP Transceiver provide complete official RoHS, CE and FCC certification documents to satisfy enterprise environmental safety audit standards?
A10: All HYTOPTODEVICE BiDi SFP Transceiver fully pass RoHS hazardous substance inspection, CE EMC and FCC safety testing. Complete official certification files can be supplied on demand for bidding, customs clearance and internal compliance audits.
Q11: How much extra recurring labor expense will emergency on-site module replacement bring for remote branch network nodes?
A11: This BiDi SFP Transceiver undergoes rigorous long-term stability testing to achieve ultra-low field failure rates. Fewer unexpected hardware faults at off-site monitoring locations significantly cut overtime labor and emergency maintenance overhead for remote sites.
