The BiDi SFP Transceiver serves as a direct pin-to-pin replacement for Juniper OEM SFP-1GBX-20U-SC-JU, delivering stable 1.25Gbps single-fiber bidirectional transmission up to 20km over standard 9/125μm single-mode fiber. Designed with simplex SC port and Tx1310nm transmit / Rx1550nm receive wavelength configuration, this bidirectional optical hardware cuts fiber core consumption in half, bringing remarkable cost savings for enterprise campus networking, FTTx broadband access and long-distance IP camera monitoring systems.
Fully compliant with SFP MSA SFF-8431/SFF-8472 and IEEE 802.3z global standards, this Juniper compatible BiDi SFP Transceiver supports real-time DDM/DOM digital diagnostic monitoring and safe hot-swap operation. Every finished unit passes 24-hour continuous aging testing to guarantee consistent error-free gigabit performance for long-term commercial rack deployment.
3. Free Custom EEPROM & Bulk OEM Service
We provide free EEPROM firmware rewrite and basic bulk OEM labeling services for all batch orders of this BiDi SFP Transceiver. Preload matched vendor ID data to remove transceiver error prompts; customized packaging is available for large-scale project deployment with zero hidden service or tool fees.
Primary Application Scenarios
As an economical single-fiber bidirectional networking solution, the 1.25G 20km SC BiDi SFP Transceiver fits all network projects facing limited fiber core resources:
- Juniper enterprise campus cross-building gigabit interconnection & network renovation
- FTTB/FTTH single fiber broadband access aggregation
- IP camera long-distance fiber monitoring for factories, parks and communities
- Hospital, campus and industrial private communication backbone
- Data center low-speed gigabit aggregation structured cabling
- Network expansion projects with insufficient existing fiber pipelines
Connectivity Solutions (Applications)
1. 1G Link for Switch to Switch
2. Double Your Network Capacity
Bidirectional transmission on one fiber strand effectively doubles link capacity without laying new fiber. It delivers a low-cost bandwidth expansion solution for Brocade 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 Module 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 Module undergoes full real-machine testing on Brocade, Huawei, H3C and other mainstream hardware. We verify link handshake, DDM precision and hot-swap performance under real network load, eliminating on-site compatibility risks.
5. Comprehensive Factory Testing for Stable Performance
Each BiDi SFP Module passes strict QC tests including high/low temperature aging, plug-pull 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 Module complies with universal MSA standards and features stable pre-calibrated vendor ID coding. Regular Brocade switch firmware updates will not trigger compatibility failures, and we supply free re-flashing support if rare recognition issues arise after system upgrades.
Q2: Can this BiDi SFP Module lose signal synchronization when paired with old legacy single-fiber media converters?
A2: This BiDi SFP Module uses standard gigabit WDM timing circuits to maintain steady signal sync with most aging media converter hardware. We provide complimentary pre-deployment compatibility verification for legacy equipment before bulk shipment.
Q3: Will inferior internal chips inside this transceiver cause excessive signal jitter and added network latency?
A3: Every BiDi SFP Module uses top-tier imported FP laser and PIN receiver chips. Full factory signal testing restricts jitter and latency within strict industry thresholds, delivering smooth low-delay gigabit transmission under full production traffic loads.
Q4: Will short-distance testing without an optical attenuator permanently overload and ruin the internal optical receiver chip?
A4: Our operation manual specifies an optical attenuator is mandatory for links under 5km. Uncontrolled high transmit power on short fiber strands will saturate the receiver and lead to irreversible hardware damage of this BiDi SFP Module.
Q5: Could defective low-grade BiDi SFP modules trigger electrical short circuits and damage costly Brocade switch slots?
A5: Each BiDi SFP Module passes complete electrical safety screening during production, equipped with built-in overcurrent and short-circuit prevention circuits. Standard PCB and metal housing design eliminates risks of short-circuit harm to enterprise switch hardware.
Q6: Are there dimensional defects on the module casing that lead to tight jamming when plugging into standard SFP ports?
A6: All BiDi SFP Module housings are precision machined to official MSA dimensional tolerances. The perfectly sized metal shell enables smooth repeated hot-swap insertion and removal without stuck or jammed port issues.
Q7: Why do different distributors offer drastically different price points for BiDi SFP modules with identical official specifications?
A7: Wide price disparities stem from varying chip quality, factory QC standards and after-sales service levels. As direct manufacturer HYTOPTODEVICE, we deliver consistent factory direct pricing with premium components and full lifecycle technical support, eliminating middleman markup costs.
Q8: How lengthy and complicated is the warranty exchange workflow for faulty BiDi SFP transceivers?
A8: We maintain a simplified streamlined warranty replacement process. Simply submit fault test screenshots and product photos, and we arrange free replacement shipments with minimal lead time, no cumbersome cross-region return formalities required.
Q9: Will 1.25G gigabit bandwidth turn into a transmission bottleneck if our business network traffic expands sharply down the line?
A9: This BiDi SFP Module delivers full symmetrical 1.25G bandwidth optimized for access layer, IP surveillance and out-of-band management links. For heavy core uplink expansion demands, we offer compatible 10G high-speed BiDi optical modules as direct upgrade options.
Q10: How much extra operational labor cost will emergency on-site module replacement bring for remote branch network nodes?
A10: This BiDi SFP Module undergoes rigorous long-term stability testing to achieve ultra-low field failure rates. Fewer unexpected hardware faults at off-site monitoring and branch locations effectively slash extra emergency maintenance overtime and service labor expenses.
