Description

The JL308A-BCC is a drop-in compatible replacement for the Aruba JL308A. This QSFP+ transceiver operates as a plug-and-play solution in Aruba switches with 40G QSFP+ ports, enabling 40 Gigabit Ethernet connectivity over duplex multimode fiber. - Compliant with QSFP+ MSA and IEEE 802.3ba standards, guaranteeing full interoperability with Aruba platforms and other 40GBASE-SR-BD compliant equipment - QSFP+ form factor with duplex LC connector, 40Gbps data rate, 832-918nm wavelength range supporting bidirectional transmission - Reaches 100m on OM3 fiber and 150m on OM4/OM5 multimode fiber, reusing existing 10G duplex infrastructure for 40G migration - Digital Optical Monitoring (DOM) support provides real-time access to transmit power, receive power, temperature, voltage, and bias current parameters - Hot-swappable design for zero-downtime installation in data center aggregation switches, campus backbone uplinks, and 40G Ethernet applications - Operates at dual wavelengths (Ch1: 850nm/Ch2: 900nm) with bidirectional signaling, delivering 20Gbps per channel over two fibers for aggregate 40G throughput

Features

• QSFP+ MSA and IEEE 802.3ba compliance ensures seamless operation in any QSFP+ 40G port, with guaranteed interoperability across multi-vendor 40GBASE-SR-BD implementations
• Bidirectional architecture transmits and receives simultaneously on two wavelengths (850nm/900nm) over duplex fiber, enabling 40G speeds on the same cabling infrastructure used for 10G links
• Each wavelength carries 20Gbps in full-duplex mode, with independent transmit and receive channels multiplexed within the transceiver for aggregate 40Gbps throughput
• Commercial temperature range (0-70°C) suits standard data center and enterprise aggregation environments, with hot-swap capability allowing field replacement without powering down the host switch
• DOM functionality exposes real-time diagnostics via I2C interface per QSFP+ MSA specification, allowing proactive monitoring of optical power budgets, temperature margins, and link health
• Optical budget of 2dB minimum supports typical duplex MMF patch panel configurations with headroom for connector insertion loss and fiber attenuation on OM3 and OM4 plants
• Enables cost-effective 10G-to-40G migration by reusing existing duplex LC fiber infrastructure, avoiding the expense of parallel 12-fiber MPO cabling required by 40GBASE-SR4

FAQs

Q: Will this work in place of the Aruba JL308A?
A: Yes. The JL308A-BCC is fully compatible with the Aruba JL308A based on QSFP+ MSA compliance, IEEE 802.3ba 40GBASE-SR-BD standard, duplex LC interface, and 40Gbps data rate. It is plug-and-play in any Aruba switch with QSFP+ ports that support the original JL308A, including uplink and aggregation ports.

Q: Which Aruba platforms support this transceiver?
A: This transceiver is compatible with Aruba switches featuring QSFP+ 40G ports, including the 2930M series and other platforms with 40GbE-capable uplink slots. Verify that your switch runs firmware supporting 40GBASE-SR-BD on the target port. ArubaOS-CX platforms are confirmed compatible; for legacy ArubaOS switches, verify 40G BiDi support in release notes.

Q: What is the difference between the 850nm/900nm bidirectional wavelengths and how do they enable duplex transmission?
A: This BiDi transceiver uses wavelength division multiplexing over two fibers. Channel 1 transmits at 850nm and receives at 900nm, while Channel 2 transmits at 900nm and receives at 850nm. Each wavelength carries 20Gbps bidirectionally, aggregating to 40Gbps. A pair of BiDi transceivers must be installed at both ends to complete the link, with each transceiver's Tx wavelength matching the opposite end's Rx.

Q: Can I mix OM3 and OM4 fiber in the same link, and what reach should I expect?
A: You can mix OM3 and OM4 in a single link, but the reach is limited by the lower-grade fiber. If any segment is OM3, design for 100m maximum. If the entire link is OM4 or OM5, you can reach 150m. The 2dB optical budget accommodates typical patch panel and connector losses, but verify your total link loss budget includes all splices, connectors, and fiber attenuation.

Q: Does this transceiver support 4x10G breakout mode like 40GBASE-SR4 modules?
A: No. The 40GBASE-SR-BD standard uses two wavelengths over duplex fiber, not four parallel lanes. It cannot be broken out into 4x10G links. If you need breakout functionality, use a 40GBASE-SR4 module with MPO/MTP connector and a breakout cable. This BiDi module is designed for native 40G links over existing duplex LC fiber infrastructure only.
