Key Features of LINK-PP LS-BL553101-40C 155M SFP
LINK-PP LS-BL553101-40C is a commercial-grade 155M SFP BiDi transceiver that packs a 40km reach, distinct bidirectional wavelengths, and a simplex LC interface into a compact single-fiber solution. Built to operate reliably between 0 and 70°C, it also integrates digital diagnostics to track optical telemetry in real time. This module balances robust hardware specifications to deliver stable, long-range link connectivity.
LINK-PP LS-BL553101-40C 155M SFP Optical Module
This module is fully compliant with the SFP MSA and SFF-8472 industry standards. These specifications ensure strict physical dimensions and full hardware compatibility with standard network ports. The hot-pluggable design allows for easy installation without powering down the host system.
LS-BL553101-40C: 155 Mbps Connectivity for SONET Infrastructure
This transceiver operates at a fixed data rate of 155Mbps to support legacy telecom setups. It is designed to match the precise timing requirements of standard SONET infrastructure, SDH links, and Fast Ethernet lines. This specific speed standard ensures reliable traffic flow across older utility networks.
LS-BL553101-40C Module with 1550nm-TX/1310nm-RX Wavelength
The module utilizes a bidirectional optical path with a 1550nm transmitter and a 1310nm receiver. It combines a DFB laser with a PIN photo detector to isolate the incoming and outgoing signals on one fiber strand. This exact wavelength separation prevents signal interference between the two channels.
This transceiver is engineered to maintain a stable optical power budget over single-mode fiber (SMF) links up to 40km. It manages signal attenuation and chromatic dispersion across these medium-haul distances. The extended reach makes it highly effective for connecting separate facilities or regional network nodes.
LS-BL553101-40C Module with Simplex LC Interface
Featuring a single simplex LC connector port, this module permits two-way traffic over just one optical fiber. This design cuts fiber cable requirements in half and optimizes space inside high-density patch panels. It simplifies physical fiber management by eliminating the need for dual-strand patch cords.
LS-BL553101-40C Module with DOM for Real-Time Monitoring
The integrated Digital Optical Monitoring (DOM) interface tracks real-time internal telemetry metrics. It allows network administrators to view live data for operating temperature, supply voltage, laser bias current, and transceiver optical power. These diagnostic data points help technicians quickly identify and troubleshoot physical link issues.

For our municipal surveillance network, we deployed these 155M SFP BiDi transceivers to run over a single-mode fiber infrastructure. The simplex LC configuration significantly reduced our patch panel density, while the 40km reach allowed us to connect outlying camera nodes back to the core routing cabinet without mid-span repeaters. Real-time DOM telemetry showed a highly stable TX power of -4.5 dBm and excellent RX sensitivity, proving the optical power budget is perfectly engineered for long-range, fast Ethernet backhaul.

For our long-distance SCADA telemetry backhaul, we needed a cost-efficient yet robust SFP that could reliably traverse 36km of overhead single-mode fiber. This 155M BiDi transceiver proved to be the ideal fit, showing outstanding resistance to polarization mode dispersion and external temperature fluctuations. The DDM telemetry remains perfectly linear throughout continuous operation, giving us high confidence in our remote link monitoring and preventing unnecessary truck rolls for manual physical layer checks.

Our current fiber deployments heavily rely on maximizing existing physical plant assets, which makes single-fiber simplex LC technology indispensable. Testing these 155M 40km BiDi SFP transceivers over a 30km single-mode span yielded highly consistent optical power margins, leaving plenty of headroom to prevent receiver saturation. The mechanical build is highly impressive, featuring a sturdy bail latch that locks firmly into the SFP slot and detaches cleanly, which makes high-density patch bay reconfigurations much easier for our field techs.

The optical budget on these single-mode SFP transceivers is outstanding, easily reaching our remote monitoring station at 38km. The only drawback is that the international shipping and handling fee to our region was quite steep. Next time, we will buy in larger bulk quantities to distribute the logistics costs better.

This simplex LC BiDi SFP performs exceptionally well with incredibly accurate real-time DOM monitoring over our fiber network. However, our shipment was held at the border for two days because of a minor clerical error on the shipping invoice. Customer service resolved the issue quickly, but the customs delay was still a bit frustrating.
