Can this 155M BiDi SFP transceiver reach up to 15km under typical insertion loss scenarios?

Yes, the link budget is rated for up to 15km over high-quality single-mode fiber infrastructure under standard attenuation parameters.

What module do I need to deploy on the opposite end of the fiber link?

You must pair it with the complementary 1550nm-TX/1310nm-RX 155M BiDi SFP module to establish a proper link connection.

We need to purchase 500 155M SFP BiDi modules for an ISP network rollout. Is there a bulk discount?

Absolutely! Please contact our sales team directly for tiered wholesale pricing and customized shipping options.

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✧)

Using these to link an older telecom rack to our core network. Finding reliable 155M SFP optics transceiver with real-time DOM can be tough now, but these LINK-PP ones are top tier.

This 155M BiDi SFP modules perform perfectly on our devices, but the shipping carrier delayed the delivery by two days, which pushed back our maintenance window. Product itself is flawless and the DOM metrics are highly accurate, just wish logistics was faster.

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.

Solid 155M BiDi SFP. The 1310nm-TX and 1550nm-RX matching works perfectly over our existing single-mode fiber infrastructure. No CRC errors detected after a week of heavy testing. (o^▽^o)

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.
