Description

Parallel single‑mode 40G QSFP+ transceiver for up to 1 km over OS2 SMF using an MPO/MTP‑12 interface. Supports 4x10G breakout to LC via an MPO‑to‑4xLC harness when the switch/port supports breakout mode. Ideal for spine/leaf or aggregation links that require longer reach on single‑mode without duplex LR4.

Features

- 1 km single-mode reach with parallel 1310 nm lanes
- MPO/MTP-12 interface enables high-density cabling
- Supports 4x10G breakout for flexible aggregation
- Low power and hot-pluggable QSFP+ form factor
- Standards-based interoperability (MSA/PSM4-aligned)

FAQs

Q: Can this module break out to 4x10G?
A: Yes, with an MPO-to-4xLC harness and a switch/port that supports 4x10G breakout.

Q: What cable/connector do I need?
A: Use an MPO/MTP-12 male trunk; the module has an MPO-12 female interface.

Q: Is this the same as LR4 (duplex LC)?
A: No, this is a parallel single-mode module using MPO-12, not duplex LC.

Q: Which fiber type is recommended?
A: OS2 single-mode fiber for links up to 1 km.

Q: Will it interoperate with other vendors?
A: It follows MSA/PSM4 practices, but device vendor coding policies vary—check platform compatibility.
