Key Features of LINK-PP LS-BL553101-80C 155M SFP
LINK-PP LS-BL553101-80C redefines long-haul edge connectivity by packing a bidirectional 1550nm/1310nm optical engine into a standard commercial-grade hot-pluggable shell. By blending single-strand fiber efficiency with integrated telemetry, this transceiver eliminates infrastructure clutter while securing stable data links. It serves as an optimized, single-port solution for bridging distant network segments over an 80km span.
LINK-PP LS-BL553101-80C 155M SFP Optical Module
Built in strict accordance with the SFP MSA and SFF-8472 protocol frameworks, this module guarantees plug-and-play compatibility across diverse multi-vendor host platforms. These open standards ensure the transceiver communicates flawlessly with existing legacy networking switches right out of the box. It offers a seamless, standardized hardware drop-in without firmware mismatch risks.
LS-BL553101-80C: 155 Mbps Connectivity for Enterprise Backhaul
Locking in a steady 155Mbps throughput, this module provides the dedicated bandwidth necessary to anchor corporate backhaul routes and remote node links. It acts as the primary data highway connecting distant regional offices back to the central corporate core. This makes it an ideal fit for legacy Fast Ethernet networks or STM-1 telecom operations.
LS-BL553101-80C Module with 1550nm-TX/1310nm-RX Wavelength
The module utilizes a 1550nm-TX and 1310nm-RX wavelength pairing to separate upstream and downstream traffic over a solitary glass strand. Inside, a narrow-linewidth DFB laser pairs with a highly sensitive PIN photo detector to isolate transmitting and receiving paths cleanly. This bidirectional signaling doubles your data routing capacity without requiring physical cabling upgrades.
Equipped with a robust optical power budget, this transceiver effortlessly spans distances up to 80km across single-mode fiber runs. The hardware is tuned to withstand the natural signal attenuation that occurs over extreme fiber lengths. It enables direct site-to-site links, completely cutting out the high cost of maintaining midway regeneration points.
LS-BL553101-80C Module with Simplex LC Interface
Utilizing a compact simplex LC receptacle, the transceiver slashes overall fiber infrastructure requirements down by exactly 50 percent. This design lets operators extract double the utility from their existing fiber distribution panels without pulling new cables through conduits. The streamlined connector profile also optimizes physical space in high-density rack setups.
LS-BL553101-80C Module with DDM for Real-Time Monitoring
The Digital Diagnostic Monitoring (DDM) function acts as an internal health check by streaming live telemetry straight to the host switch. Administrators can instantly pull precise readouts of module temperature, voltage, laser bias currents, and optical power levels. Having this continuous data feed makes it easy to spot fiber degradation before it triggers a complete link outage.

Before buying in bulk, our engineering team ran this 155M 80km SFP module through a comprehensive optical spectrum analyzer bench test. The 1550nm TX laser exhibits an incredibly narrow spectral width, which is key to preventing chromatic dispersion over long physical spans. The measured optical extinction ratio is excellent, ensuring high signal contrast and keeping our bit error rate below the strict threshold. The transceiver pulls very little current even at its maximum rated operating temperature, preventing localized heating inside dense switches. The physical build, latch mechanism, and optical path design are all top-tier.

In our utility monitoring network, maximizing existing physical assets is critical, which is why we transitioned to these simplex LC BiDi modules. Operating over a single SMF strand, this transceiver successfully eliminated the need to lease secondary fibers for our telemetry return paths. The internal digital diagnostics (DOM) show that even inside our outdoor trackside cabinets, the SFP case temperature runs remarkably cool. The 1550nm-TX distributed feedback laser outputs a highly stable optical signal that effortlessly bridges our remote substation nodes. It is an exceptionally built commercial-grade SFP that conforms to all relevant MSA signaling standards.

Using these BiDi SFP transceivers for a remote campus link spanning about 65km. Setting up a TX1550/RX1310 BiDi at one end and the counterpart at the other was straightforward. Signals are incredibly stable. DDM monitoring via CLI shows optical TX power within perfect spec range. Excellent budget-friendly alternative to Cisco original optics.

Excellent optical parameters (1550nm-TX / 1310nm-RX) with clean signals over our 68km link. The delivery was delayed by two days because the courier routed it to the wrong local hub. Once it finally arrived, the installation was a breeze and the performance is a solid 5/5. Just wish local shipping was smoother.

We integrated these 155M SFP transceivers to support legacy STM-1 SDH add-drop multiplexers across a sprawling municipal WAN. The physical link immediately established a solid connection over our single-mode fiber backbone, showing no signs of optical jitter or frame slippage. Thanks to the high-sensitivity PIN receiver, the module handles minor path splices and patch panel attenuation with plenty of margin to spare. The hot-pluggable SFP form factor fits perfectly into standard cages, making active swaps completely seamless. It has proven to be an indispensable asset for keeping our legacy carrier circuits operating smoothly.

Perfect for our substation optical network. The LS-BL553101-80C modules paired nicely with our existing single-mode fiber infrastructure. Since we were low on available fiber strands, utilizing BiDi 1550nm-TX/1310nm-RX over a single LC connector literally saved us from having to pull new cables.

Our infrastructure requires robust Fast Ethernet links to carry telemetry data from remote field sensors over 70km back to headquarters. Deploying these LS-BL553101-80C BiDi SFP modules allowed us to simplify our fiber patch panels by using a single simplex LC connector instead of duplex pairs. The metallic zinc-alloy housing offers excellent shielding against nearby high-voltage electromagnetic interference. Despite operating inside unventilated control cabinets, the SFP keeps its power consumption low and remains highly stable. We have experienced zero CRC errors or interface flapping since completing this network deployment.
