Juniper Compatible 10G SFP+ BiDi (1270nm-TX/1330nm-RX,40km,LC SMF,DOM,Industrial,Compatible With JNP-SFP-10G-BX40U-I)

Product Specifications

Key Design Benefits

• Fiber Infrastructure Cost Reduction: Single-fiber bidirectional transmission cuts required single-mode fiber cabling infrastructure by 50% compared to traditional dual-fiber duplex links.
• Industrial-Grade Thermal Reliability: Operates reliably across -40°C to +85°C, making it suitable for outdoor wireless fronthaul nodes, utility networks, and industrial control cabinets.
• 40km Long-Haul Transmission Budget: High optical launch power (-1 to +5 dBm) and sensitive PIN receiver (< -15 dBm) provide a robust optical link budget for 40km links.
• Juniper Junos OS Interoperability: Pre-programmed with Juniper compatible EEPROM identification to ensure recognition and port initialization in Junos OS platforms.
• Second-Source Supply Continuity: Offers network engineering and procurement teams a qualified industrial-grade alternative to mitigate component lead times and single-source risks.

Optical Architecture & Diagnostic Performance

The LS-BL273310-40I incorporates electro-optical subsystems directly within a compact metallic SFP+ enclosure to ensure signal integrity across single-fiber 10G optical channels.

Transmitter & Receiver Subsystems

The transmitter incorporates an uncooled 1270nm DFB laser driver supplying -1 to +5 dBm optical launch power. The receiver incorporates a 1330nm WDM filtered PIN photodiode with an integrated trans-impedance preamplifier (TIA) providing < -15 dBm receiver sensitivity and a 0.5 dBm overload threshold across 10.7Gbps data streams.

Complementary BiDi Pairing

Designed to pair across a single fiber strand with a complementary downstream 10G BiDi transceiver operating at TX 1330nm / RX 1270nm (such as Juniper JNP-SFP-10G-BX40D-I) to complete the bidirectional optical communication link.

Digital Diagnostic Monitoring (DOM)

An SFF-8472 compliant MCU control unit monitors real-time operational parameters over a 2-wire serial interface. Monitored metrics include transmitted optical power, received optical power, laser bias current, module operating temperature, and internal supply voltage.

Mechanical & Interface Specifications

Enclosed in a standard metal SFP+ housing featuring a latching bail mechanism for secure insertion and removal. The optical interface uses an industry-standard Simplex LC/UPC receptacle compatible with single-mode fiber (SMF G.652) patch cables. The module operates within an industrial temperature range of -40°C to +85°C and satisfies Class 1 laser safety requirements.

Target Applications

• Juniper 10GBASE-BX40 Industrial Links: Single-fiber 10 Gbps Ethernet uplinks for outdoor Juniper ACX-series and MX-series routers.
• 5G eCPRI, CPRI & OBSAI Wireless Fronthaul: Extended-temperature (-40°C to +85°C) optical transport between Remote Radio Units (RRU) and Baseband Units (BBU).
• Metro & Regional Telecom Backhaul: Single-fiber bidirectional 10G optical links for enterprise campus networks and regional service provider aggregation rings.

Juniper JNP-SFP-10G-BX40U-I Replacement Compatibility Checklist

When evaluating the LINK-PP LS-BL273310-40I as an alternative to Juniper JNP-SFP-10G-BX40U-I, network engineers should verify the following parameters against their system specification:

• BiDi Wavelength Pair Matching: Confirm that the local SFP+ slot requires TX 1270nm / RX 1330nm and pairs with a complementary TX 1330nm / RX 1270nm BiDi module (e.g. JNP-SFP-10G-BX40D-I) at the remote end.
• 40km Fiber Link Budget Verification: Confirm single-mode fiber (SMF G.652) cable attenuation stays within the net optical link budget for up to 40km.
• Thermal Class Verification: Confirm that your deployment environment requires the extended industrial (-40°C to +85°C) operating temperature rating.
• Juniper Switch EEPROM Compatibility: Confirm that target Juniper switch or router ports support 10G SFP+ BiDi modules and SFF-8472 DOM protocols.
