The BiDi SFP Transceiver serves as a direct pin-to-pin replacement for Juniper OEM SFP-1GBX-20D-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 Tx1550nm transmit / Rx1310nm 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
By enabling bidirectional data transmission on a single fiber strand, this professional BiDi SFP Transceiver effectively doubles the carrying capacity of original fiber links without laying new fiber cables. It provides a low-cost, high-efficiency bandwidth expansion solution for Juniper enterprise network upgrades and operator FTTx access network 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 (OOB) 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 production batch of this BiDi SFP Transceiver undergoes full real-machine compatibility testing on Juniper, Huawei, H3C and other mainstream network hardware. We verify link handshake stability, DDM monitoring precision and hot-swap performance under real network load, eliminating all on-site deployment compatibility risks.
5. Comprehensive Factory Testing for Stable Performance
Each BiDi SFP Transceiver passes strict standardized quality control tests, including high/low temperature aging cycles, repeated plug-pull durability inspection, optical power consistency calibration and 72-hour continuous operation testing. Rigorous mass production QC ensures consistent batch performance and extended service life for all commercial network deployments.
FAQ
Q1: How to avoid "unsupported transceiver" alerts and forced port shutdowns on the switch OS?
A1: Our HYTOPTODEVICE BiDi SFP Transceiver comes with free pre-flashed Juniper matched EEPROM data for bulk orders. The preloaded vendor ID can be fully recognized by Junos OS, eliminating warning popups and port deactivation without complicated on-site CLI configuration.
Q2: Is EEPROM firmware re-flashing complicated if we plan to switch to other brand network hardware later?
A2: We take care of all EEPROM reprogramming work in our factory before shipment at zero extra cost. No professional tools or on-site technical operations are needed when you migrate to different brand switches.
Q3: Will practical transmission distance be shorter than marked 20km caused by regular fiber attenuation losses?
A3: This BiDi SFP Transceiver reserves a full 12dB optical power budget to offset fiber insertion loss and splice attenuation. Under standard single-mode fiber conditions, stable 20km transmission can be guaranteed within the rated operating range.
Q4: Will low-grade internal chip hardware lead to obvious signal jitter and increased transmission latency on live business links?
A4: Every BiDi SFP Transceiver is equipped with premium imported laser and receiver chips. Strict factory signal testing controls jitter and latency within industrial standard ranges to maintain smooth low-delay gigabit data forwarding under full traffic loads.
Q5: How to confirm this transceiver is fitted with high-performance DFB laser instead of low-cost unstable laser components?
A5: We can provide complete component inspection and optical test reports for any BiDi SFP Transceiver batch upon request. Every unit undergoes full optical power testing to verify stable laser quality before delivery.
Q6: Can this transceiver withstand extreme temperature fluctuations inside uncooled outdoor industrial cabinets?
A6: This commercial-grade BiDi SFP Transceiver works steadily from 0℃ to +70℃, suitable for indoor rack deployment. For unconditioned outdoor industrial cabinets with wider temperature swings, we offer dedicated industrial temperature range optical modules as an alternative.
Q7: Why are product labels tiny or unclear, causing trouble for field staff to confirm specs on-site?
A7: We print large, clear wavelength, model and distance labels on each BiDi SFP Transceiver housing for easy on-site identification. Distinct visual marks are added to distinguish Tx1550/Rx1310 paired variants to avoid matching errors.
Q8: Can we access timely English technical support if bulk transceivers malfunction unexpectedly during live production operation?
A8: 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.
Q9: Will this BiDi SFP Transceiver exceed standard power draw limits and add extra load to the Juniper switch’s overall power budget?
A9: The transceiver adopts low-power optical circuits with power consumption strictly controlled within MSA standard limits. It will not surpass the power threshold of standard SFP slots or create extra power pressure on Juniper enterprise switches.
Q10: What eco-friendly recycling and compliant disposal solutions are available for BiDi SFP Transceivers once they reach end-of-life service?
A10: All BiDi SFP Transceivers fully comply with RoHS standards without hazardous heavy metal components. We provide professional waste optical module recycling guidance for enterprise buyers, supporting standardized environmental disposal and centralized recovery of scrapped transceivers.
