The BiDi SFP Transceiver is a pin-to-pin drop-in replacement for Extreme OEM SFP-1GBX-U-SC-EX, delivering stable 1.25Gbps single-fiber bidirectional transmission up to 20km over standard 9/125μm SMF. Equipped with simplex SC port and Tx1310/Rx1550 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.
Primary Application Scenarios
As an economical single-fiber bidirectional networking solution, the 1.25G 20km SC BiDi SFP Transceiver fits all network projects with limited fiber core resources:
- Extreme enterprise campus cross-building gigabit interconnection & legacy network renovation
- FTTB/FTTH single fiber broadband access aggregation layer construction
- IP camera long-distance fiber monitoring for factories, industrial parks and residential communities
- Hospital, campus and enterprise private communication backbone networks
- Data center low-speed gigabit aggregation structured cabling systems
- Network expansion & upgrade projects with insufficient existing fiber pipelines
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.
4. Tested in The Host Device to Prove Interoperability
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: Is re-flashing EEPROM firmware complicated if we switch hardware vendors down the line?
A1: Our team handles all EEPROM reprogramming for every BiDi SFP Transceiver order at no extra cost. All firmware adjustments are completed at our factory before shipment, requiring no complex tools or on-site operations when you migrate to new brand switches.
Q2: Will short-distance testing without an optical attenuator permanently overload and destroy the built-in optical receiver chip?
A2: Links under 5km must use an optical attenuator as stated in our operation guidelines. Uncontrolled high transmit power will saturate the receiver and cause irreversible hardware damage to this BiDi SFP Transceiver.
Q3: How can we confirm this transceiver is equipped with premium DFB laser instead of low-grade unreliable laser components?
A3: We provide full component inspection reports for all BiDi SFP Transceiver batches upon request. Every unit is fitted with standardized high-performance laser parts and undergoes optical power testing to prove stable laser quality before delivery.
Q4: Does dimensional inaccuracy on the module casing lead to tight jamming during insertion into standard SFP ports?
A4: Each BiDi SFP Transceiver shell is precision manufactured to strict MSA dimensional standards. The perfectly sized metal housing enables smooth repeated hot-swap without stuck or jammed port issues.
Q5: Why do multiple distributors offer vastly different price points for BiDi SFP transceivers with identical technical specs?
A5: Price gaps come from differences in internal chip grade, factory QC standards and after-sales service packages. As direct manufacturer HYTOPTODEVICE, we offer transparent factory pricing with top-tier components and full lifecycle technical support, free of middleman markup.
Q6: Can we access timely English-language technical support if bulk transceivers fail unexpectedly during live production operation?
A6: We provide round-the-clock English-speaking engineering support for all BiDi SFP Transceiver buyers. Our team delivers fast remote fault diagnosis, compatibility verification and troubleshooting to resolve urgent production network failures.
Q7: Does the product packaging offer sufficient shock and dust resistance to shield fragile optical components during long international shipping?
A7: Every BiDi SFP Transceiver is individually sealed in anti-static shockproof boxes with protective dust caps. Thick buffered outer cartons prevent collision and contamination damage across cross-border logistics.
Q8: Will deploying these third-party BiDi SFP transceivers invalidate the original hardware warranty of our Extreme brand switches?
A8: This BiDi SFP Transceiver fully complies with universal SFP MSA mechanical and electrical standards and does not damage switch hardware. Major network manufacturers do not void equipment warranties for MSA-compliant third-party optical modules, and we can supply official spec documents for warranty support.
Q9: Do low-cost unbranded optical transceivers carry hidden firmware loopholes or network security risks?
A9: Our BiDi SFP Transceiver adopts standardized closed-loop firmware without unoptimized open code. Strict factory firmware auditing eliminates potential backdoors or security vulnerabilities that exist on generic no-brand low-end transceivers.
Q10: How much extra recurring labor expense will emergency on-site module replacement bring for remote branch network nodes?
A10: This BiDi SFP Transceiver passes rigorous long-term stability testing to maintain 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.
