Key Features of LINK-PP LS-BL315501-15C 155M SFP
LINK-PP LS-BL315501-15C is a single-strand bidirectional transceiver engineered to optimize single-mode fiber infrastructure for long-range links. This hot-pluggable SFP module integrates dual-wavelength separation, digital diagnostics, and a 155Mbps data rate into a compact form factor. It provides a highly efficient and stable hardware footprint for standard telecom and network access deployments.
LINK-PP LS-BL315501-15C 155M SFP Optical Module
This transceiver strictly adheres to the global SFP Multi-Source Agreement (MSA), guaranteeing seamless physical and electronic interoperability across diverse vendor hardware platforms. Furthermore, it incorporates SFF-8472 compliance to deliver comprehensive digital diagnostic monitoring for immediate system validation.
LS-BL315501-15C: 155 Mbps Connectivity for Single-Fiber Topologies
Delivering a steady 155Mbps throughput, this unit handles standard Fast Ethernet traffic with excellent timing accuracy. By utilizing single-strand single-mode fiber for simultaneous dual-direction traffic, it minimizes cabling complexity and cuts infrastructure deployment costs in half.
LS-BL315501-15C Module with 1310nm-TX/1550nm-RX Wavelength
The device employs a bi-directional wave-division strategy, launching upstream data at 1310nm while collecting downstream traffic at 1550nm. This clear spectral decoupling isolates incoming and outgoing signals on the same glass core, completely removing cross-channel crosstalk.
With an optimized internal power budget, the transceiver maintains a clear optical path across single-mode fiber spans extending up to 15km. This capacity easily satisfies the physical reach demands of regional aggregation networks and distant edge connections.
LS-BL315501-15C Module with Simplex LC Interface
Utilizing a single-port simplex LC receptacle, the hardware ensures a tight, vibration-resistant fiber connection within high-density switch environments. This compact interface layout simplifies patch cable management and reduces the space needed in distribution panels.
LS-BL315501-15C Module with DOM for Real-Time Monitoring
Onboard Digital Optical Monitoring (DOM) continuously extracts key telemetry data, including internal temperature, supply voltage, and transmitter-receiver power thresholds. Operators can use these continuous metrics to spot signal degradation early and handle maintenance before an actual link failure occurs.

We ran a comprehensive benchmarking suite on these LS-BL315501-15C BiDi SFP modules for our campus-wide surveillance network expansion. Operating at 155Mbps over a 14.2km single-mode fiber span, the link budget margin remained highly stable at ~18dB, easily clearing our strict internal validation thresholds. The digital optical monitoring feature integrated smoothly with our PRTG monitoring system, providing real-time telemetry on transceiver health. The savings from switching to a simplex single-fiber infrastructure allowed us to reallocate budget to high-res cameras. Truly impressive performance. (✧ω✧)

Our engineering firm specialized in base station backhaul solutions recently certified the LS-BL315501-15C for field deployment. We rigorously tested the 155M BiDi SFP across a variety of insertion loss profiles. The 1310nm-TX and 1550nm-RX separation is cleanly filtered with zero cross-talk or back-reflection anomalies over a 15km single mode fiber layout. The simplex LC connector has low insertion loss, and the DOM alerts triggered correctly when we simulated an over-attenuated fiber bend. This level of reliability makes it our go-to choice for contract infrastructure upgrades.

As a lead network engineer overseeing a metro-wide utility grid, finding dependable 155Mbps Fast Ethernet optics that support accurate DOM can be challenging. We deployed the LINK-PP LS-BL315501-15C across 20 remote substations. The 1310nm-TX/1550nm-RX combination works flawlessly over our single-mode fiber infrastructure. During our stress tests, the modules maintained stable optical output power and receiver sensitivity down to -28dBm without a single CRC error or packet loss. The simplex LC interface allowed us to maximize our existing fiber plant without running costly new cables. Outstanding enterprise-grade build quality!

Modules perform exactly as advertised for 155Mbps networks. Just make sure you order the complementary model (1550nm-TX/1310nm-RX) for the opposite side because the manual didn't emphasize this enough for junior technicians. Otherwise, excellent stability and DOM readings.

Great price for a 15km single mode transceiver. The simplex LC connector works great and saved us fiber cores. However, the outer retail box arrived slightly squashed. Fortunately, the inner packs were fine and all SFP modules tested out perfectly on our outers.
