Juniper SFP-10G45-BX80 Compatible SFP+ 10G BiDi Module | 10GBASE-BX80-U 80km Tx1490Rx1550nm Bulk Factory Wholesale | HYTOPTODEVICE

Q1: Does this module support auto-negotiation if plugged into a 1G port? A: No, this 10G BiDi SFP+ transceiver cannot auto-negotiate down to 1G speed. It is fixed at 10.3125Gbps per 10GBASE-BX80-U standard, and inserting it into a 1G SFP port will result in no link. HYTOPTODEVICE 10G BiDi modules require host SFP+ ports that natively support 10G rate for normal operation.

Q2: Can this 1490/1550nm BiDi module pair with standard 1310/1550nm modules? A: No, cross-wavelength pairing between 1490/1550 BiDi and 1310/1550 transceivers will fail to establish link. Each BiDi transceiver relies on dedicated transmit/receive wavelength matching; you must use the complementary 1550/1490 BiDi partner module at the far end. HYTOPTODEVICE supplies matched BiDi module pairs for 80km single-fiber deployments.

Q3: Can I run this 1490/1550nm module on a single strand of fiber (BiDi/Simplex)? A: Yes, this 10GBASE-BX80-U module is purpose-built for simplex single-strand single-mode fiber. It uses WDM technology to send and receive signals over one OS2 fiber core, cutting fiber consumption in half. HYTOPTODEVICE BiDi transceivers are widely selected by integrators to save fiber resources on long-haul point-to-point links.

Q4: Does this module work over Multimode Fiber (MMF)? A: No, this 80km BiDi transceiver only works with OS2 single-mode fiber and cannot transmit over multimode fiber. MMF has large core diameter and high signal dispersion, which cannot support 80km 10G long-distance transmission. HYTOPTODEVICE recommends simplex LC OS2 SMF cable for all 10G BX80-U installations.

Q5: Why is 1490/1550nm chosen instead of 1270/1330nm for 80km reaches? A: 1490/1550nm window delivers much lower fiber attenuation for long-distance transmission. 1490nm has ~0.25dB/km loss and 1550nm ~0.20dB/km, far better than 0.35dB/km at 1270/1330nm. HYTOPTODEVICE selects this wavelength set to achieve stable 80km reach on OS2 single fiber for metro networking projects.

Q6: Can I use an 80km module for short-distance links (e.g., 5km or 10km)? A: Yes, but optical attenuation must be added to protect the APD receiver. The high transmit power of this 80km BiDi module will overload the APD chip on short links below 10km; a 12–15dB simplex LC attenuator is required. HYTOPTODEVICE can supply matching attenuators together with bulk module orders for short-range testing.

Q7: How does chromatic dispersion impact performance over an 80km span at 10G speeds? A: Chromatic dispersion widens optical pulses and raises bit error rate on 80km 10G links. OS2 single-mode fiber is optimized to reduce dispersion in 1490/1550nm window, keeping signal distortion within acceptable limits for 10GBASE-BX80-U. HYTOPTODEVICE pre-tests all modules to meet dispersion budget requirements for 80km single-fiber connections.

Q8: Is the APD receiver easily damaged by optical power spikes? A: The APD receiver is sensitive to excessive incoming optical power spikes above -7dBm. Overpowered input will permanently burn the APD chip, most commonly during short link testing without attenuators. HYTOPTODEVICE marks this risk in product guidelines and provides technical tips for integrators during bulk procurement.

Q9: What is the operating temperature range (Commercial vs. Industrial)? A: The standard commercial-grade model operates from 0°C to 70°C for indoor cabinet deployment. Industrial grade (-40°C ~ +85°C) is available as custom OEM order. HYTOPTODEVICE supports temperature customization for wholesalers who need modules for outdoor or harsh environment projects.

Q10: Does this module comply with IEEE 802.3ae, SFF-8472, SFF-8431 and SFF-8432 specifications? A: Yes, this 10GBASE-BX80-U BiDi transceiver meets IEEE 802.3ae, SFF-8472, SFF-8431 and SFF-8432 requirements. These standards define 10G Ethernet, SFP+ mechanical form factor and digital diagnostic monitoring rules. HYTOPTODEVICE strictly follows these industry specs to guarantee stable interoperability for wholesalers and integrators.

Q11: Is this product RoHS, CE, and FCC compliant? A: Yes, HYTOPTODEVICE 10G BX80-U BiDi transceiver passes RoHS, CE and FCC certification. All raw materials and assembly processes meet global environmental and EMC rules. We can provide full certification documents for distributors and buyers for customs clearance and project audit.

Q12: Are replacement units readily available if a module fails in a critical link? A: Yes, HYTOPTODEVICE maintains in-stock inventory for fast replacement shipment. Failed modules under warranty can be returned for replacement or refund per our terms. Global wholesalers and system integrators can secure stock reservation for critical network projects with bulk purchase contracts.

Q13: How often should I clean the optical interfaces on 80km modules? A: Clean simplex LC optical interfaces before installation and re-clean every 6–12 months for long-running 80km links. Dust and oil residue increase insertion loss and degrade long-distance signal quality. HYTOPTODEVICE recommends LC fiber cleaning pens for regular maintenance by network O&M teams.

Q14: Can I use this module to bridge connections between two remote data centers 60km apart? A: Yes, this 80km-rated BiDi module works reliably for 60km point-to-point single-fiber data center interconnection. It has sufficient power budget to cover 60km OS2 fiber plus normal splice and connector loss. HYTOPTODEVICE offers bulk pricing for data center interconnection projects for global buyers.

Q15: Will this module work over dark fiber leased from a telecommunications provider? A: Yes, this 10GBASE-BX80-U BiDi transceiver works on leased dark single-mode OS2 fiber. You only need to confirm the fiber type and total link loss before deployment. HYTOPTODEVICE’s technical team can assist integrators to complete link budget calculation for leased dark fiber projects.
