This module is fully compliant with the multi-vendor SFP MSA standard and the SFF-8472 specification for digital diagnostics. It incorporates a highly stable 1310nm DFB laser transmitter coupled with a high-sensitivity PIN photodetector. These standard-compliant components guarantee seamless hot-swappable installation and multi-platform compatibility across enterprise networking hardware.
LS-BL315501-80I: 155 Mbps Connectivity for BiDi Network Topologies
Operating at a reliable Fast Ethernet and SDH/SONET data rate, this device provides a dedicated 155Mbps pipeline for targeted utility, transportation, and industrial automation networks. By leveraging advanced bidirectional signaling, it doubles fiber capacity in existing infrastructures without forcing costly layout expansions. This makes it an efficient fit for legacy transport upgrades and remote field communications.
LS-BL315501-80I Module with 1310nm-TX/1550nm-RX Wavelength
The transceiver utilizes a precise 1310nm-TX and 1550nm-RX wavelength split to handle simultaneous transmitting and receiving over a single strand of glass. This distinct frequency division multiplexing approach eliminates internal crosstalk and maximizes signal integrity across long distances. It allows network planners to optimize dark fiber assets by running independent upstream and downstream paths on a single core.
Engineered with a robust optical power budget, this extended-reach module easily overcomes attenuation barriers to sustain links up to 80km. It is specifically designed to bridge the gap between distant substations, trackside enclosures, and regional aggregation hubs without needing intermediate optical amplifiers. The rugged internal components ensure minimal bit error rates even at the farthest edge of the fiber run.

Most commercial optics fail when ambient cabinet temperatures drop past -20°C, leading to frequency drift and link flaps, which is why we chose this explicitly rated -40°C to 85°C module for our smart grid substations. Deployed inside unheated roadside enclosures during a severe winter storm cycle, our monitoring systems tracked the DDM internal module temperature at -32°C while maintaining stable Tx power at -3dBm. The laser stability at 1310nm transmission is remarkable, showing zero wavelength drifting under extreme thermal stress.

Solid hardware, took an extra day to clear customs. The industrial-grade temperature performance is great for our outdoor highway cameras. The DDM readouts match our Fluke testers exactly. Deducted one star because customs processing delayed delivery by 24 hours. Will order earlier next time.

Great long-distance BiDi module, but dispatch date slipped by 24 hours. The wavelength separation provides a clean signal, and the modules operate flawlessly across our rural link. The order took two extra business days to leave due to a minor delay in custom firmware flashing. The deployment team had to push their site visit back slightly, but the optics perform beautifully.

Perfect fit for legacy STM-1/OC-3 lines. A lot of vendors are phasing out 155M optics, so finding reliable long-reach 80km SMF modules is a lifesaver. Running these for a utility company pipeline telemetry network and the connection is rock solid.

While the industry is focusing on high-speed data center links, many of our critical transit signaling networks still rely on stable 155M Fast Ethernet and SDH/OC-3 protocols over long distances. Finding high-quality 80km transceivers with Simplex LC interfaces that bypass strict vendor checks on legacy MSA equipment was a massive bottleneck until we tried these LINK-PP 155M SFP modules. The EEPROM is coded correctly to avoid "unsupported transceiver" errors, and the single-mode fiber physical layer mechanics are flawless. We observed no receiver saturation issues on our 45km test spans, though we utilized a small attenuator to align with long-term safety margins.

Rugged optics for harsh environments. We run these BiDi SFP modules inside outdoor cabinets for a railway signaling network. Temperatures hit 50°C in summer and below zero in winter, but these industrial-grade (-40°C to 85°C) modules haven't flinched. Highly recommended!

When you pack dozens of SFP modules into a single high-density switch chassis, heat dissipation becomes a major bottleneck even for low-speed 155M monitoring links. The LS-BL315501-80I features an exceptional zinc alloy housing that dissipates heat efficiently, running significantly cooler than the generic transceivers we previously sampled on our bench. According to our chassis temperature sensors, the thermal footprint remains uniform, preventing localized hotspots that threaten power supply stability. The hot-pluggable mechanism is smooth and latches securely without requiring excessive force, protecting the delicate internal backplane pins during maintenance.
