Description

The X130 10G SFP+ BiDi transceiver is a bidirectional optical module with an LC connector, built for long-reach 10G links over a single strand of single-mode fibre. It suits sites where fibre count is limited and a 40km link is needed between two switches or between a switch and a remote device.

This module is the downlink end of a BiDi pair, transmitting at 1330nm and receiving at 1270nm. It delivers 10G over a single simplex LC fibre at distances up to 40km. Because BiDi optics use different wavelengths in each direction, this downlink module must be installed opposite its uplink counterpart, the X130 10G SFP+ LC BiDi 40km-Uplink transceiver (JL739A).

It belongs to the X130 BiDi family, which also includes JL737A (10km-Uplink), JL738A (10km-Downlink) and JL739A (40km-Uplink). Choose JL740A when the far end of the link uses the 40km uplink module.

Enquire with XS Network Tech for new or used pricing and availability.

FAQs

Q: What does this transceiver pair with?
A: It is the downlink end of a BiDi pair and must be installed opposite the X130 10G SFP+ LC BiDi 40km-Uplink transceiver, JL739A.

Q: Can I use two JL740A modules on the same link?
A: No. BiDi optics use different transmit and receive wavelengths, so each link needs one downlink module and one uplink module.

Q: How many fibre strands does it need?
A: It needs a single strand of single-mode fibre with LC connectors, as the module transmits and receives over the same fibre.

Q: How does it differ from the 10km BiDi modules?
A: The 40km downlink supports links of up to 40km. The 10km BiDi modules in the family, JL737A and JL738A, are intended for shorter links and must be paired with each other.

Q: What is the wavelength plan for this module?
A: It transmits at 1330nm and receives at 1270nm, which is the opposite of the uplink module at the far end.
