We need to deploy these optics in unconditioned outdoor cabinets. Is there an industrial wide-temperature version available?

The standard LS-BL55491G-60C operates at commercial temperatures (0°C to 70°C). For harsh outdoor enclosures, we offer the industrial-grade version (LS-BL55491G-60I) engineered to operate from -40°C to +85°C. You can select the industrial variant directly on our product line page.

What fiber patch cables and matching transceiver model should we pair with this 1550nm-TX / 1490nm-RX 60km module?

This module requires a single-mode fiber (SMF 9/125碌m) patch cable with a Simplex LC connector. To establish a functional BiDi optical link over 60km, the far end must be paired with the complementary wavelength transceiver: LS-BL49551G-60C (1490nm-TX / 1550nm-RX)

Will these LS-BL55491G-60C modules work smoothly in Cisco Catalyst switches and MikroTik routers without triggering unrecognized transceiver warnings?

Yes, absolutely. Our modules come pre-coded and tested for full OEM compatibility across major networking platforms, including Cisco, MikroTik, Juniper, and Ubiquiti. They report standard MSA EEPROM data, ensuring seamless plug-and-play operation and real-time DOM telemetry without software flags.

We are planning a regional network upgrade and need to purchase around 300 units. Do you offer tiered volume pricing or custom B2B quotes?

Yes, we provide aggressive tiered volume pricing for bulk B2B purchases. Orders above 100 units qualify for discounted wholesale pricing, and for quantities over 250 units, our enterprise procurement team can issue custom quotes along with flexible net payment terms.

Are these 1G BiDi SFP transceivers compliant with international industry standards and environmental regulations?

Yes. The LS-BL55491G-60C fully complies with the SFP Multi-Source Agreement (MSA), IEEE 802.3ah 1000BASE-BX60-D standards, RoHS, CE, and FCC guidelines. Each unit undergoes strict optical parameter testing before shipment to guarantee global compliance.
